A lightning-bomb detonated over Manila.

"There is your message," van Hoek said pointing toward the city, "and your groundlings will go into it tonight, and dwell in that Message for the next two months. You have dwelt there, too, Jack—did the Message not reach your ears?"

"I may have heard faint whisperings—could you amplify it?"

"Of all the enterprises to which a man can devote his energies," van Hoek began grudgingly, raising his voice, "long-distance trade is the most profitable. It is what every Jew, Puritan, Dutchman, Huguenot, Armenian, and Banyan aspires to—it is what built the Navies and palaces of Europe, the Court of the Great Mogul in Shahjahanabad, and many other prodigies besides. And yet in the world of trade, it is common knowledge that no circuit—not the slave trade of the Caribbean, not the spice trade of the Indies—exceeds the Manila-to-Acapulco run in sheer profit. The wealthiest Banyans in Surat and bankers in Genoa lay their perfumed heads on silken pillows at night, and dream of sending a few bales of cargo across the Pacific on the Manila Galleon. Even with all the dangers, and the swingeing duty that must be shelled out to the Viceroy, the profits never fall below four hundred percent. That city is founded upon such dreams, Jack. We are all going to go there now."

Van Hoek finally shut up at this point, and in the silence that followed he realized that, down below him on the upperdeck, his rant was being dutifully translated into diverse heathen tongues. The translators took more or less time to relate it, depending on the wordiness of their several languages and how much they edited out or how freely they embellished. But when the last of them finally wound up his oration, a light pattering started up. Jack flinched, thinking it was more hail. But then it grew into a heavy, stomping roar, and he recognized it as applause. Dappa thrust both index fingers into his mouth and emitted a piercing noise. Van Hoek seemed startled at first; then understanding dawned, and he turned to Jack, removed his hat, and bowed.

JANUARY 1700

At bottom, all our experience assures us of only two things, namely, that there is a connection among our appearances, which provides us the means to predict future appearances with success, and that this connection must have a constant cause.

Berlin, Prussia

To Mr. Daniel Waterhouse, Chancellor

Massachusetts Bay Institute of Technologickal Arts

Newtowne, Massachusetts Bay Colony

Dear Daniel,

The appearance of your letter on the doorstop of my Academy brought unlooked-for cheer to an otherwise frosty Berlin day, which developed into pleasure when I read that your Institute now has a roof over its head, and joy when you expressed your continued desire to collaborate with me. I confess that when two years passed without word from you, I thought you had been killed by Indians or hanged for a witch!

Much has happened since we last exchanged letters. You have probably noticed that I have a new address (Berlin) and what is more, it is in a new kingdom (Prussia). The monarch you knew by the name Elector Frederick III of Brandenburg is now called King Frederick I of Prussia. He is the same chap, still joyfully married to the same Sophie Charlotte, living in and ruling from the same palace that he built for her in Berlin, but he has (through machinations that would only disfigure this letter) persuaded the Holy Roman Emperor in Vienna (still Leopold I, in case you have not been keeping up) to suffer him to use the title of King. His family (the Hohenzollerns) have been the Dukes of Prussia as well as Electors of Brandenburg for so many generations that it made sense to merge the two countries. The result is called Prussia but still ruled out of Brandenburg.

Sophie is as vigorous and crafty as always. She and her daughter have deemed it unwise to give the appearance of being too close, as this would give the idea, to friends and foes alike, that Sophie was now controlling an immense German state stretching from Königsberg in the east almost all the way west to the Rhine. For various reasons she prefers to seem instead like a contented elderly widow; so she lets her son George Louis think that he rules Hanover, and she travels to Berlin only occasionally, to pinch the cheeks of her grandchildren and put on a great show of harmlessness.

I shuttle back and forth between Hanover and Berlin all the time, to the point where the more bloody-minded Berlin courtiers were beginning to whisper that I must be acting as a secret conduit for Sophie's influence. The problem being that I could not point to any official reason why I should be in Berlin so frequently. The real reasons (to have interesting conversations with Sophie Charlotte and her brilliant circle of friends, and to tutor Princess Caroline) are scoffed at by that sort of person.

Hence the Berlin Academy, of which I am the first president. It seems like the sort of institution that a King ought to found (the fashion having been established, of course, by your Charles II with his Royal Society) and so doing it makes Frederick's new title seem that much more richly deserved. And being its president gives me an excuse to be in Berlin whenever I wish.

And it is well that I have something to belong to other than the Royal Society! By now you have probably received copies of the dreadful publications of last year: volume three of Wallis's work, in which my twenty-five-year-old correspondence with Newton is exposed to the whole world, and made to seem like something other than what it really was, and Fatio's Lineae Brevissimi Descensus, which is yet another bitter assault on me. A school of thought seems to be developing, according to which I had no inkling of the calculus until I stole the whole thing from Newton around 1677. Apparently my years of toil in Paris under the tutelage of Huygens count for nothing!

I had best not begin to rant and rave about this. Let me instead turn to some of your questions.

Yes, I still correspond with Eliza. How could I not? But, as many people do when they have children, she settled, at some point, into a more steady kind of life, and since has not written to me as frequently. When the peace treaty was signed between France and the allies three years ago, her title as Duchess of Qwghlm was recognized by the French court, and she began to travel frequently to England—though almost never with her husband. She keeps a town-house near St. James's and has even journeyed to Qwghlm occasionally to renew her ties to the place of her birth. Once or twice a year she journeys to my part of the world to spend time with her bastard son and to pay a call on Sophie. Her husband, with his long-standing connexions to the Navy, is more fond of Qwghlm than she is, and seems to phant'sy that the massive Castle there has the makings of a country house—though it is difficult to think of a more outlandish and wretched setting for one! And so he is there several months this last year overseeing a project to rebuild one part of that ruin, and make it over into a villa and a proper seat for the nascent Duchy of Arcachon-Qwghlm. Some in London grumble that he is getting ready to turn Qwghlm into a French naval base, à la Dunkerque. But I cannot imagine Eliza allowing any such thing to happen.

As a way of making a name for herself in London society she supports a charity for Vagabond-soldiers, which has been a pet cause of hers for some years. After the peace treaty was signed and the Tories came into power, the size of England's army was drastically reduced, many regiments disbanded, and out-of-work soldiers have been roaming around the country making trouble ever since. Eliza's obvious concern for them is an implicit criticism of Tory policies, which should put her in a good position if the Juncto ever returns to power.
