And first they touched at two small islands which lie nearly opposite Communipaw, and which are said to have been brought into existence about the time of the great irruption of the Hudson, when it broke through the Highlands and made its way to the ocean.[27] For, in this tremendous uproar of the waters we are told that many huge fragments of rock and land were rent from the mountains and swept down by this runaway river, for sixty or seventy miles; where some of them ran aground on the shoals just opposite Communipaw, and formed the identical islands in question, while others drifted out to sea, and were never heard of more. A sufficient proof of the fact is, that the rock which forms the bases of these islands is exactly similar to that of the Highlands; and moreover, one of our philosophers, who has diligently compared the agreement of their respective surfaces, has even gone so far as to assure me, in confidence, that Gibbet Island was originally nothing more nor less than a wart on Anthony's nose.[28] Leaving these wonderful little isles, they next coasted by Governor's Island, since terrible from its frowning fortress and grinning batteries. They would by no means, however, land upon this island, since they doubted much it might be the abode of demons and spirits, which in those days did greatly abound throughout this savage and pagan country. Just at this time a shoal of jolly porpoises came rolling and tumbling by, turning up their sleek sides to the sun, and spouting up the briny element in sparkling showers. No sooner did the sage Oloffe mark this than he was greatly rejoiced. "This," exclaimed he, "if I mistake not, augurs well--the porpoise is a fat, well-conditioned fish--a burgomaster among fishes--his looks betoken ease, plenty, and prosperity. I greatly admire this round fat fish, and doubt not but this is a happy omen of the success of our undertaking." So saying, he directed his squadron to steer in the track of these alderman fishes. Turning, therefore, directly to the left, they swept up the strait, vulgarly called the East River. And here the rapid tide which courses through this strait, seizing on the gallant tub in which Commodore Van Kortlandt had embarked, hurried it forward with a velocity unparalleled in a Dutch boat, navigated by Dutchmen; insomuch that the good commodore, who had all his life long been accustomed only to the drowsy navigation of canals, was more than ever convinced that they were in the hands of some supernatural power, and that the jolly porpoises were towing them to some fair haven that was to fulfill all their wishes and expectations.
