Guert was well aware that the _Noank_ had taken out what were called "letters of marque and reprisal," and was therefore a regularly authorized and commissioned commerce-destroyer. She was one of many. In several of the colonial ports, north and south, precisely such sea-wolves had long since made their preparations, and some were already at sea. They were making serious havoc and were soon to make more in the widely distributed, ocean-going commerce of Great Britain. It was a cruel, destructive, uncivilized kind of warfare, but it was customary among all the nations of the earth. In like manner, at this very date, British privateers were out after American prizes. These latter, moreover, had the regular cruisers of England as auxiliaries. Less agreeably, sometimes, the warships came in as business rivals or to claim a division of spoils. The Yankee privateers themselves constituted nearly the entire navy of the United States. Sunrise does not come early in the month of January. It seems to come earlier and there is more of it, if the weather is clear. On the next morning after the arrival of the Trenton news, however, a thick white mist came drifting up New London harbor from the sea. There was only a light wind blowing from the westward, and it promised to be one of the hazy days of winter, such as come before a thaw. "This 'ere is jest the thing for us," remarked Captain Avery, when he came out to see about the weather. "It's the right kind o' breeze for a schooner, and it's jest the wrong thing for a square rig. We can spread more canvas for our draft and tonnage than that king's brig can, anyhow." There was no one to dispute him, and he and Vine and Guert were shortly on their way to the wharf. The Yankee shipbuilders, with abundance of the best timber at hand and any number of bays and inlets to work in, had constructed admirable shipyards upon plans of their own. Point after point they had gone away from antiquated models, and they had already made many important improvements in the building and rigging of all kinds of craft. Before many years, the whole sea-going world was to be forced to recognize their superiority. All of the _Noank's_ crew were on board when her captain reached her, and he at once gave orders to cast off from the wharf. Only a very few of her friends came down to see her go. Farewells had been already said, for the greater part, and even the sailors' wives had been aware that there would be no lingering. The Long Island whaleboat was nowhere to be seen. It might be that her hardy oarsmen, their errand accomplished, had set out to recross to their own shore under the cover of darkness.
