iries regarding the history and durability of paper boats occasionally reach me through the medium of the post-office. After all the uses to which paper has been put during the last twenty years, the public is yet hardly convinced that the flimsy material, paper, can successfully take the place of wood in the construction of light pleasure-boats, canoes, and racing shells. Yet the idea has become an accomplished fact. The success of the victorious paper shells of the Cornell College navy, which were enlisted in the struggles of two seasons at Saratoga, against no mean antagonists,--the college crews of the United States,--surely proves that in strength, stiffness, speed, and fineness of model, the paper boat is without a rival. [Illustration: A FULL-RIGGED NAUTILUS CANOE.] When used in its own peculiar sphere, the improved paper boat will be found to possess the following merits: less weight, greater strength, stiffness, durability, and speed than a wooden boat of the same size and model; and the moulded paper shell will retain the delicate lines so essential to speed, while the brittle wooden shell yields more or less to the warping influences of sun and moisture. A comparison of the strength of wood and paper for boats has been made by a writer in the Cornell Times, a journal published by the students of that celebrated New York college: "Let us take a piece of wood and a piece of paper of the same thickness, and experiment with, use, and abuse them both to the same extent. Let the wood be of one-eighth of an inch in thickness--the usual thickness of shell-boats, and the paper heavy pasteboard, both one foot square. Holding them up by one side, strike them with a hammer, and observe the result. The wood will be cracked, to say the least; the pasteboard, whirled out of your hand, will only be dented, at most. Take hold and bend them: the wood bends to a certain degree, and then splits; the pasteboard, bent to the same degree, is not affected in the least. Take a knife and strike them: the wood is again split, the pasteboard only pierced. Place them on the water: the wood floats for an indefinite time; the pasteboard, after a time, soaks, and finally sinks, as was to be expected. But suppose we soak the pasteboard in marine glue before the experiment, then we find the pasteboard equally as impervious to the water as wood, and as buoyant, if of the
