The United States section, after all its troubles in getting under weigh--the very appropriation itself not having been made until after the English exhibit had all been selected, arranged on the plan and the catalogue printed--is a collection to be proud of. The arrangement is good, except for a little crowding. The space in the Palais is forty thousand square feet, with thirty thousand additional in an outside building. The latter has the agricultural implements, mills, scales, wagons and engines, with the displays of oak and hickory in the forms of wheels, spokes and tool-handles, which are exciting so much interest in Europe at the present time. There is no good substitute for hickory to be found in Europe, and it is the difference between American hickory and English ash which causes the great disparity between the proportions of American and English carriage-wheels. That we should copy the latter for the sake of a fashion is marvellous. It is not to be denied that the ingenuity and versatility of Americans have caused them to excel other nations in many lines of manufacture. The public opinion of Europe regards their triumphs in agricultural implements as the most remarkable; but the nation which made the machine-tools for the government manufactories of small-arms both of England and Germany has established its right to the first rank in that class of work also. The system of making by rule and gauge the separate parts, which are afterward fitted, has come to be known as the "American system," and is exemplified in the magnificent collection of the American Watch Company of Waltham; the Wheeler & Wilson sewing-machine, which is the only sewing-machine with interchangeable parts at the Exposition; the Remington rifle and shot-gun, and the Colt revolvers. [Illustration: INDIANS MAKING KASHMIR SHAWLS.] There is nothing in the building in better taste in its line than the Tiffany gold and silver ware, and the carriages of Brewster are generally admired. Carriages are, however, such a matter of fashion that an exhibit of that kind cannot suit all nations, and what one considers graceful is to another strange and bizarre. There is no question of the fine quality, however: of course a nation with elm for hubs and ash for spokes wonders at American temerity in making wheels so light, and the casual observer thinks our roads must be better than the European to justify them. As one English builder has, however, contracted lately with an American firm for five hundred sets of wheels, they will have an opportunity soon of testing the quality of our woods.
