But, as no such clumsy vessel could have been employed in a seaway, her movements must have been confined to rivers or inland waters. It is just possible that such and similar vessels might at some period have been used for ferrying rivers[28] or lakes. Very extraordinary notions, however, appear to have been propounded about, and subsequently to, this period, and, as a matter of curiosity, I furnish one of these taken from Hollar’s engravings, which does not appear to have been noticed by any writer on this interesting subject. The original engraving, bearing date A.D., 1653, is to be found in the British Museum. Various details[29] are furnished by the inventor. [Illustration] Besides the detailed explanation of this extraordinary looking craft, which in “length is 72 feet, the height 12, the breadth 8,” there is beneath the print the following description: “The true and perfect form of the strange ship built in Rotterdam, 1653. The inventor of it doth undertake in one day to destroy a hundred ships, it can go from London to Rotterdam and back again in one day, and in six weeks to go to the East Indies, and to run as fast as a bird can fly. No fire, nor storme, nor bullets can hinder her unless it please God. Although the ships mean to be safe in their havens, it is in vain, for she shall come to them in any place. It is impossible for her to be taken unless by treachery, and she cannot be governed by any one but himself” (the inventor?). The motive power is not described, and there is no further trace of the ship, of which the illustration is a vertical section. She was built at the time when the Dutch were in the zenith of their power, and most likely proved as worthless as numerous other inventions since produced, though curious as showing the attention devoted at this period to wheels as a mode of propelling vessels. [Sidenote: Absurd patents.] However, we find in the records of our own Patent Office, that Englishmen were not behind the Dutch in curious and frequently very absurd inventions. Thus, in 1675, one Miller[30] patented a windmill fixed to a vessel’s deck to turn an endless rope, and thus, by “two toothed wheels,” to drive a couple of paddle-wheels. Such commonplace matters as storms at sea or adverse winds, still less the likelihood of the whole of the top weight he proposed to erect on the deck of his vessels being blown or rolled overboard, do not appear to have entered into the fertile and imaginative brain of the inventor.
