Mr. Wienan, an American gentleman, is having a yacht built

for him in the Thames which is to create a perfect revolution in shipbuilding. She is built of pure steel, in the shape of a cigar, the cylinder being 256 ft. long, with a diameter of 16 ft. at the broadest part, and nothing but two funnels, a short deck, and a little bit of the cylinder will appear out of water. She is to be driven by three cylinder engines, and a shaft with screws at each end, and it is believed that the engines can be so worked with safety as to yield 2,500 horse-power. The architect expects a speed of twenty-six or thirty miles an hour, but to get it Mr. Wienan should carry out George Stephenson's suggestion, and electroplate his vessel. She is to be launched with her steam up in August.
