Neal McBurnett (see “References” on page 129) analyzed the network structure of the Web of Trust digraph. He examined the digraph for path lengths, connectedness, degree of scale, and other features. 128 CHAPTER SEVEN Mark Reiter and Stuart Stubblebine created PATHSERVER (see “References” below), a way to evaluate multiple signature paths between keys. These analyses are inspired by the Web of Trust and derive from the Web of Trust, but we must note that they are orthogonal to the Web of Trust proper. It is an integral feature of the Web of Trust that it consists of viewpoints; it may be considered relativistic, in that no frame of reference in the Web of Trust is inherently more valuable or trusted than any other.

But large, disconnected networks of people may find it difficult to use the basic Web of Trust because there are few paths between people who do not already know each other. As the Web of Trust includes more nodes with relatively few edges, finding trust paths becomes difficult. The Web of Trust works at its best with groups of people who have some connections. It does not work well with a large, ubiquitous network like the Internet. However, there are two saving graces—modern social networking reconstructs the sorts of small networks that are ideal for the Web of Trust. It may not work well on the Internet as a whole, but it works well in the Internet that most of us use.

…

It is an integral feature of the Web of Trust that it consists of viewpoints; it may be considered relativistic, in that no frame of reference in the Web of Trust is inherently more valuable or trusted than any other. The trust portion of the Web of Trust relies completely on the user-specific trust markings and the weights that the key holder places on keys. The mesh of keys is an interesting object that we believe is useful on its own, and helps the overall use of the Web of Trust, but it is an orthogonal construct to the Web of Trust. The Web of Trust’s directed graph says something about the people in it. What it says, though, is open to both further research and debate. References Allman, E., J. Callas, M. Libbey, J.

The higher the trust level, the more confidence Bob can have in using the key. A perennial question about the web of trust, however, is whether or not it scales. Small groups of people can create a web of trust easily, especially if they can meet each other in person. What happens when we try to make the web of trust work for, say, a consumer and a merchant who have never met before? The conventional wisdom is that the web of trust does not scale. After all, there is a limit to how many people Alice and Bob can know. The most frequently cited alternative to the web of trust is a so-called Public Key Infrastructure. Some trusted root party issues certificates for keys in the system, some of which go to parties that can issue certificates in turn.

Darryl and I, when we traded keys, that was kind of a mini-keysigning party, one with only two sad and geeky attendees. But with more people, you create the seed of the web of trust, and the web can expand from there. As everyone on your keyring goes out into the world and meets more people, they can add more and more names to the ring. You don't have to meet the new people, just trust that the signed key you get from the people in your web is valid. So that's why web of trust and parties go together like peanut butter and chocolate. # "Just tell them it's a super-private party, invitational only," I said. "Tell them not to bring anyone along or they won't be admitted."

Making things well-known is just as hard as keeping them secret. Think about it -- how many billions of dollars are spent on shampoo ads and other crap, just to make sure that as many people know about something that some advertiser wants them to know? There's a cheaper way of fixing man-in-the-middle: the web of trust. Say that before you leave HQ, you and your bosses sit down over coffee and actually tell each other your keys. No more man-in-the-middle! You're absolutely certain whose keys you have, because they were put into your own hands. So far, so good. But there's a natural limit to this: how many people can you physically meet with and swap keys?

If you can use it and pay for it, you can find an Epinion about it. Members can rate each review as “Highly Recommended,” “Recommended,” “Somewhat Recommended, or “Not Recommended.” Members can click a button next to the name of an Epinionator and add him or her to a personal “web of trust.” People who trust each other inherit each other’s webs of trust. Although webs of trust are an official feature of Epinions, the first web of mistrust appeared spontaneously, created by a user. Epinions continuously publishes updated ratings for the community to see. This feature is mentioned by some habitual users who joke about their prolific contributions as a compulsion: “I am addicted to a drug called Epinions.

…

eBay, dominant survivor of the e-commerce bubble, uses a reputation system to facilitate billions of dollars worth of transactions for people who don’t know each other and who live in different parts of the world. Epinions pays contributors of the most popular online reviews of books, movies, appliances, restaurants, and thousands of other items. Epinions’s reputation system enables people to rate reviewers and to rate other raters through “webs of trust.” The most trusted reviewers are read by more people and therefore make more money. Slashdot and other self-organized online forums enable participants to rate the postings of other participants in discussions, causing the best writing to rise in prominence and most objectionable postings to sink.

The MIT researchers started a company named Firefly to commercialize Ringo and sold it to Microsoft in 1998. Microsoft eventually implemented its own version of Firefly’s “digital passport” technology.2 Ringo turned out to be the progenitor of an evolutionary lineage. Finding new books, movies, or music is a popular pursuit, but it represents only one form of the myriad webs of trust that support markets, scientific enterprises, businesses, and communities. Consider the history of online knowledge-sharing economies. One of the most seductive aspects of social cyberspace is the way virtual communities share useful information. I remember how excited I became in the 1980s, when the never-ending “Experts on the Well” discussion inspired people in the Well, a virtual community of a few thousand, to compete for the honor of providing the fastest and most accurate answers online to questions posed by other members of the community.3 This custom is more sophisticated than automated word-of-mouth systems like Ringo because it requires each human recommender to keep in mind many other people’s intellectual preferences, gleaned solely from online conversations.

His public key had been vouched for by some of the most respected figures in the world of digital privacy. That made it a reliable node in the crowdsourced, decentralized verification system that encryption users call a “web of trust.” It’s easy to go down a rabbit hole when you’re talking about how to build trust in the digital world. That’s why so much writing about blockchain is inscrutable. But the basic principle behind using a web of trust to leverage credibility is simple. In an online article explaining why it’s so important, Henk Penning, a developer at Utrecht University, arrived at a conclusion that would please fans of The Matrix.

Linux Security Cookbook by Daniel J. Barrett, Richard E. Silverman, Robert G. Byrnes

Debian, GnuPG, MITM: man-in-the-middle, web of trust

GnuPG allows keys to be signed, indicating that the signer vouches for the key. It also lets you control how much you trust others to vouch for keys (called "trust management"). When you consider the interconnections between keys and signatures, as users vouch for keys of users who vouch for keys, this interconnected graph is called a web of trust . To participate in this web, try to collect signatures on your GnuPG key from widely trusted people within particular communities of interest, thereby enabling your key to be trusted automatically by others. Public-key methods are also the basis for digital signatures : extra information attached to a digital document as evidence that a particular person created it, or has seen and agreed to it, much as a pen-and-ink signature does with a paper document.

…

A keyserver does absolutely nothing to assure the ownership of keys. Anyone can add a key to a keyserver, at any time, with any name whatsoever. A keyserver is only a convenient way to share keys and their associated certificates; all responsibility for checking keys against identities rests with you, the GnuPG user, employing the normal GnuPG web-of-trust techniques. To trust a given key K, either you must trust K directly, or you must trust another key which has signed K, and thus whose owner (recursively) trusts K. The ultimate way to verify a key is to check its fingerprint with the key owner directly. [Recipe 7.9] If you need to verify a key and do not have a chain of previously verified and trusted keys leading to it, then anything you do to verify it involving only computers has some degree of uncertainty; it's just a question of how paranoid you are and how sure you want to be.

…

But the more smartly selected checks you make, the more independent servers and systems an attacker would have to subvert in order to trick youand thus the less likely it is that such an attack has actually occurred. This process will also merge new signatures into an existing key on your key ring, if any are available from the keyserver. 7.21.4 See Also For more information on the web of trust, visit http://webber.dewinter.com/gnupg_howto/english/GPGMiniHowto-1.html. Recipe 7.22 Revoking a Key 7.22.1 Problem You want to inform a keyserver that a particular public key (of yours) is no longer valid. 7.22.2 Solution Create a revocation certificate: $ gpg --gen-revoke --output certificate.asc key_id Import the certificate: $ gpg --import certificate.asc Revoke the key at the keyserver: $ gpg --keyserver server_name --send-keys key_id Delete the key (optional) $ gpg --delete-secret-and-public-key key_id THINK CAREFULLY BEFORE DELETING A KEY.

Whether or not you believe that it is possible to develop real trust-filled relationships online, I think it’s reasonable to consider Willow Brugh’s view: “I think we are able to open the door to build trust more quickly and to be more aware and accepting through online interaction. I think we’re also able—╉and this is the key point—╉to expand the web of trust, where I might not trust you directly but I have met someone that you know and trust them explicitly, and therefore I’ll trust you as well.” I am really fascinated by this possibility, and we have only begun to scratch the surface of what’s possible when we connect seven billion problem solvers—╉and then connect those problem solvers with needed data and tools.

A remarkable accomplishment for someone who’s been with the project this long, but not so surprising for someone whom no other developer has, as far as I can tell, ever claimed to have met in person.21 When it became clear that Miller, who occupied a crucial technical position in the project at that time, was outside the web of trust, there was such alarm that within three days, two developers drove to meet the individual in question and succeeded in bringing him into the cryptographic network. The developers’ strong reactions demonstrated the essential nature of these infrequent face-to-face interactions and significance of verifying the identity of one of their technical guardians. Integration into Debian’s web of trust is thus a vital first step in new maintainers’ integration into the Debian project. This process connects and leads into the second and often most rigorous part of the NMP: philosophy and procedures.

…

This is a process of identity verification that can then be used over the Internet to confirm, with certainty, that an individual is who they say they are. By requiring new developers to obtain the signature of an existing Debian developer, the NMP integrates them into what they call a cryptographic “web of trust.” Because nearly every hacker within Debian has a key signed by at least one existing developer, and because many developers have keys signed by numerous others (the stronger the connected set of signatures is, the more trustworthy it is considered), nearly all maintainers are connected. Debian can use cryptographic algorithms to prove that most every developer met at least one other developer, who in turn met at least one other developer, and so forth, until every developer is linked.

…

It is a step that brings a developer closer to a new social localization within a larger ethical and technical project of developers who have also undergone the same reflective exercise. Through this reconfiguration of temporality, developers after the NMP can be said to share at least three connections: they are technologically linked through the web of trust that requires them to meet at least one other developer; they share the experience of a common ritual of entry; and finally, they have started to learn a Debian-specific vocabulary with which to situate themselves within this world, formulate the broader implications of freedom, and continue the conversation on freedom, licensing, and their craft, with a wider body of developers.

Unlike the KYC solution, which seeks smarter ways for people to prove who they are, this one lowers the barrier to entry by finding efficiencies in the system itself so that it’s less important to “know your customer.” Whether WeTrust’s model works or not, it may help us learn a lot about how these new systems of algorithmic, distributed trust can interface with those old, deeply embedded social webs of trust. We think it’s important that solutions to the challenges faced by the poor aren’t just imposed in some cookie-cutter manner by Silicon Valley venture capitalists who insist they know best. Solutions must be informed by and tailored to the underlying cultural structures of the communities in question.

…

Those latter two categories have become more fluid, especially in the age of social media and as our cultures become more open to new ways of defining what it means to be human, whether that breaks down along sexual orientation, gender, or religious, racial, or ethnic grounds. What’s powerful, though, is that the technologies driving those changes now also make it possible to turn these more dynamic aspects of who we are into a means of proof—primarily in the realm of our social identity. Our circle of friends and interactions constitutes a web of trust that has its own powerful, informational value. If that circle incorporates a large number of essentially trustworthy people—no one among them is on the no-fly list, for example—it’s possible to deduce with decent probabilities that you are also trustworthy—or at least that you should be given a positive score, to be confirmed or challenged by other measures of your trustworthiness.

…

Done poorly, we are almost guaranteed to create biased benchmarks of “worthiness” that discriminate against those who, for whatever cultural, circumstantial, or personal reason, don’t meet the algorithm’s standard. Do I have better or worse credit if I view a lot of Republican political Web sites? This is dangerous territory. As pseudonymous cryptocurrency journalist Juan Galt put it, a web of trust can become an Orwellian web of shame. Influential cryptocurrency thinker Andreas Antonopoulos argues that the problem lies in trying to solve identity in the first place, which he says is in breach of what Bitcoin’s open, permissionless architecture represents. Blockchain developers building these identity/reputation tools are promoting a “relic of traditional financial systems,” he argues.

Because of this it’s been suggested that these revocation-proof CAs be marked as such in their certificates so that applications can avoid the overhead of having to check for a revocation that will never happen [149]. B A Bob Alice C D Figure 184: The web of trust PGP’s version of X.509’s hierarchical trust model is the web of trust [150], shown in Figure 184. The theory behind the web of trust is that although Alice doesn’t directly know Bob, she does know A and C, who in turn know B and D, who know Bob, and 676 PKI so Alice can build a trust link to Bob (or at least Bob’s public key) through these indirect paths. In practice though it’s doubtful that the web of trust can really deliver [151][152]149. For example when fake keys for Tor developers started appearing [153] it proved impossible to verify the developers’ genuine keys through the web of trust [154].

For example when fake keys for Tor developers started appearing [153] it proved impossible to verify the developers’ genuine keys through the web of trust [154]. This doesn’t mean that the concept can’t be usefully applied in practice though. Outside the computer security field it’s used extensively by organised-crime groups like the mafia, who employ complicated chains of introducers to prevent an outsider (typically an undercover agent) from posing as a legitimate Mafioso [155]. As an example of the kind of problems that a web-of-trust-based security system can run into, in one (informal) experiment into the effectiveness of PGP’s key distribution mechanism a professor asked his students to securely exchange PGP keys and then follow this up with an exchange of encrypted email (which in previous experiments had already proven very problematic), but with an extra twist: They were given bonus marks for spoofing keys and otherwise attacking the security of the key management process.

Since Carol knows Bob—and has earlier received a verified copy of Bob’s public key—she can establish the veracity of his signature. If it checks out, that means that Bob has really met the person who holds this new key and is implicitly telling Carol, “Hey, it’s really Alice.” So Carol can be sure that Alice is who she says she is. At least to the degree she trusts Bob. This system—known as a “web of trust”—requires some judgment on the user’s part. After all, Carol can’t be sure of Alice’s identity unless she personally knows someone who has physically met her and signed her key. What if she doesn’t know anyone who’s physically signed it? Is it worth trusting a second-level verification? Maybe her friend Bob hasn’t signed Alice’s key, but he has signed a key of someone named Ted.

…

Seeing one of those trusted introducers on a key ring would be a strong assurance of authenticity. In any case, PGP allowed users to set what cryptographer Bruce Schneier refers to as “paranoia levels”: how many levels of separation you’re willing to accept, depending on the degree to which you trust various signers. With this web of trust, a stronger encryption algorithm, a better interface, and a number of other improvements, PGP 2.0 was—unlike Zimmermann’s favorite weekend comedy show—ready for prime time. The informal team of programmers had even prepared translations of the interface in several languages, so people worldwide could use it from the day of release.

It is even possible to create a distributed control fraud, in which the mechanism of fake profits, high risk and value extraction arises without the necessary involvement of a single legally culpable actor, by assembling a set of perverse, ‘criminogenic’ incentives which make the distortions happen independently. Finally, we reach the highest level of abstraction. These frauds exploit the general web of trust which makes up a modern economy, rather than a single relationship. There are plenty of actions which are not even really crimes at all in the traditional sense – they are not obviously or intrinsically dishonest activities. Nevertheless, experience has shown us that a market economy works better if people are able to assume that they won’t be done.

Land is physical and tangible and hard to steal, but an inheritance right is something different; you can’t always tell whether it’s been stolen from you and promised to someone else. As soon as the concept of a property right was invented, as soon as ownership got more complicated than simply the ability to control things by fighting anyone else who wanted them, there is a need for a social web of trust that the rights will be respected and not misused. And where there’s trust, there’s the opportunity for fraud. Inheritances also have another important property when we look at them as potential locuses of fraud; they were one of the few ways in which abstract property rights over large and valuable things could come to be owned by women.

While some traditionalists might cheer to see the innovative troublemakers in Chicago brought low, it would be a body blow to the financial system. That system was held together by invisible strands of trust—the confidence that debts would be paid, trades would be settled, institutions would function, money would circulate. Shred that web of trust, and the system would not hold together. The Merc simply had to open on time on Tuesday; the world had to see that it and its trading firms could be trusted. These were not Chicago pit gypsies whose credit was on the line. The Merc was owed roughly $1 billion by Morgan Stanley; in turn, it was obligated to pay $670 million to Goldman Sachs and $917 million to Kidder Peabody.

…

And certainly, the MMI’s spike after Blair Hull’s buy orders would have helped stave off despair. If there was any “conspiracy,” it was an opportunistic one centered on the concealment of how widespread the trading halts were on the Big Board. The fact remains: While the market had fallen on Monday, it had almost fallen apart on Tuesday. All that had saved it was a makeshift web of trust, pluck, and improvisation—and perhaps a few bits of inspired subterfuge here and there. Only misinformed hindsight sees that midday turning point as the “end” of the 1987 crash. For Phelan and Melamed, for Ruder and Corrigan and Greenspan, for the stunned portfolio insurers in California, it was simply a fragile rally that let the market stumble toward the blessed closing bell on Tuesday without shattering the world’s confidence in America’s financial system.

The suspicion of identity cards reflects a deep characteristic of British society, which is the connection between freedom and trust. Precisely because we are free to associate as we will, to build networks and institutions and little platoons without official permission or official knowledge, there is a premium, in our society, on honesty. British society has emerged over the centuries as a self-policing web of trust between strangers. It is because each member is free to bestow trust and to earn it as he wishes that this kind of trust emerges and becomes a secure collective asset of the people who are linked by it. Mass immigration of communities who do not build trust in that way – who depend on family networks like the Sicilians or religious obedience like the Pakistanis – has jeopardized the old legacy of communal action, and reminded the British people of the downside of freedom.

If published, the findings are shared with journalists in press releases, drafted by university press offices. We expect that these findings are then reported honestly and without distortion by broadcasters and newspapers. Civil servants draft ministerial speeches that respond to these facts, including details on what the government has achieved to date. A modern liberal society is a complex web of trust relations, held together by reports, accounts, records and testimonies. Such systems have always faced political risks and threats. The template of modern expertise can be traced back to the second half of the seventeenth century, when scientists and merchants first established techniques for recording and sharing facts and figures.

CONFLICTS OF INTEREST Lurking beneath most of the issues that plague the market is one fundamental issue that will never go away: conflicts of interest. The market is all about interactions between parties and that leads to a complicated web of trust and dependency. A customer trusts her broker or investment adviser to provide good advice and best execution regardless of how the outcome affects the broker’s paycheck. Brokers trust each other to carry through on the deals they make in the market and to do so fairly. Research analysts are supposed to be objective in their analysis, rating agencies are supposed to be indifferent to the fact that the issuer is paying for the rating, regulators are supposed to focus on their current job and not what goes on their resume, lawmakers are supposed to do what is good for the market and not what is likely to get the electorate all in a lather before the next election.

It would bequeath to the next generation a society sliding into the pit of entitled individualism. In retrospect, the period of Utilitarian and Rawlsian dominance of the centre-left will come to be recognized for what it was: arrogant, over-confident and destructive. The centre-left will recover as it returns to its communitarian roots, and to the task of reconstructing the web of trust-based reciprocal obligations that address the anxieties of working families.* Similarly, the period of domination of the centre-right by assertive individualism will come to be recognized as the seduction of a great tradition by economic man. As it recovers its ethical bearings, it will return to ‘one nation’ politics.

He rarely types in one of those addresses and wonders what they have to tell him today. Mind you, he reads a lot of news—far more than I did at his age. But he goes to that news only via the links from Digg, friends’ blogs, and Twitter. He travels all around an internet that is edited by his peers because he trusts them and knows they share his interests. The web of trust is built at eye-level, peer-to-peer. Before I go on, let me acknowledge that, of course, things can go wrong. In 2005, the Los Angeles Times decided to be cyber-hip by inventing the “wikitorial,” an editorial from the paper that the public was invited to rewrite. In no time, the quality of discourse around the first wikitorial descended to the level of that on a prison yard during a riot because the Times had made a fundamental error: A wiki is a tool used for collaboration, but there was no collaborating to be done on the topic of the Times’ wikitorial—the Iraq war.

In the rare instances when these issues have been considered at all, wealthy people themselves have been identified as the key actors. This is despite recent evidence that undermine that narrative, such as media coverage of the 2012 presidential campaign of Mitt Romney, which revealed that his $250 million personal fortune was held in a complex global web of trust funds managed by a private banker at Goldman Sachs: “His Goldman investments are handled by Jim Donovan, who … gave Mr. Romney’s trusts access to the bank’s own exclusive investment funds and helped him execute an aggressive and complex tax-deferral strategy known as an ‘exchange fund’ in 2002.

I’ve hired former founders into key executive roles and personally encouraged former employees of mine to become founders themselves. And, of course, most successful people in Silicon Valley become angel investors, even if on a small scale. So the roles get deeply intertwined. It’s a reciprocal web of trust, expertise, and reputation that is an important part of why startup hubs drive so much entrepreneurial success. This career path has only recently become something widely available in contemporary economies. But I think this is just the tip of the iceberg in terms of how this professional identity will evolve in the coming years and decades.

And as so few transactions involve simultaneous exchange, that trust is embodied in money or financial instruments, which count and store the value, and allow it to be exchanged. Figure 10. Without trust, all economic transactions are like Checkpoint Charlie. It is extraordinary, when you stop to think about it, how extensive and also how delicate the web of trust represented by money has become in the modern global economy. All but a few countries are engaged in international trade and vast amounts of financial transactions cross national borders. Much of it now takes the form of electronic records on computer systems, not even paper money or bonds or shares, which are themselves abstractions.

The 3rd Baron Vestey is a close friend of the Queen, and in 1999 he became Royal Master of the Horse; an appointment that caused mild embarrassment when the Vestey Food Group was implicated in the Findus horsemeat scandal a few years back. Yet at the same time as inveigling themselves into the establishment, the Vesteys had been pioneering new ways of avoiding the tax authorities. Unbeknown to polite opinion at the time, they created a complex web of trusts and overseas companies that allowed them to become, in Nicholas Shaxson’s words, ‘among the biggest individual tax avoiders in history’. The brothers domiciled themselves in Argentina for a while and set up a secret trust fund in Paris. It all began perfectly legally, but when the British exchequer finally got word of where they were squirrelling away their millions, they began to investigate.

How the repositories of a large project are organized, or how they coalesce and combine, is again largely immaterial to the workings of Git; Git supports any number of organizational models. Remember that the repository structure is not absolute. Moreover, the connection between any two repositories is not prescribed. Git repositories are peers. So how is a repository structure maintained over time if no technical measures enforce the structure? In effect, the structure is a web of trust for the acceptance of changes. Repository organization and dataflow between repositories is guided by social or political agreements. The question is, “Will the maintainer of a target repository allow your changes to be accepted?” Conversely, do you have enough trust in the source repository’s data to fetch it into your own repository?

"None of them tried treating it as a map of a connectionist system based on the only terrestrial components anyone had ever beamed out into deep space. Except me. But then, your mother had a hand in my wetware, too." "Treating it as a map –" Amber stops. "You were meant to penetrate Dad's corporate network?" "That's right," says the cat. "I was supposed to fork repeatedly and gang-rape his web of trust. But I didn't." Aineko yawns. "Pam pissed me off, too. I don't like people who try to use me." "I don't care. Taking that thing on board was still a really stupid risk you took," Amber accuses. "So?" The cat looks at her insolently. "I kept it in my sandbox. And I got it working, on the seven hundred and forty-first attempt.

This was the Hollywood version of a “leak”: an unknown source emerging from nowhere, bearing a stupendous scoop. In the real life of a newsroom, this happened so seldom that it was tantamount to myth. Typically, I got my best stories in small pieces from people I had cultivated for years or discovered through a common web of trust, each contributing part of a whole that none would tell me directly. I could not get past the size of the archive. How many documents did it hold? The number did not matter much, but looking for it became a calming distraction. The job was unexpectedly difficult. I found no point-and-click method to count the combined contents of all those hundreds of folders.

Contrast this approach with PEM, which leaves quite a bit of information about the sender, recipient, and message in the unencrypted header. The most interesting aspect of PGP is its distributed approach to key management (see Section 8.12). There are no key certification authorities; PGP instead supports a “web of trust.” Every user generates and distributes his own public key. Users sign each other’s public keys, creating an interconnected community of PGP users. For example, Alice might physically give her public key to Bob. Bob knows Alice, so he signs her public key. He then gives the signed key back to her and keeps a copy for himself.

“For yesterday at dinner at the home of Monsieur Castan, I was treated to a description of that same system—a description so flattering that I asked him why it was not used everywhere else.” They found this amusing. “What was Monsieur Castan’s reaction to that?” asked Jacob Gold. “Oh, that other places were cold, distrustful, that the people there did not know one another so well as they did in Lyon, had not built up the same web of trust and old relationships. That they were afflicted by a petty, literal-minded obsession with specie, and could not believe that real business was being transacted unless they saw coins being physically moved from place to place.” The others looked relieved; for they knew, now, that they would not have to break this news to Eliza.
