Tiffany's exhibit has been admired and patronized, but is not quite within my range of subjects. Darling, Brown & Sharpe have their machine-tools and gauges, Bliss & Williams their presses and dies. We have the Baxter, Snyder and Lovegrove portable engines, Taylor's and Aultman's agricultural engines. Our railroad exhibit is not very full: we have a Philadelphia and Reading coal-burning locomotive, a Pullman car, the Westinghouse brake, Stephenson's street-cars, car-wheels from Baldwin's and Lobdell's: the latter also sends calender-rolls of remarkable quality. As a sort of set-off to the Austrian car-wheels which have run for twenty-one years, as previously mentioned, Lobdell has a pair which have run 245,000 miles on the Missouri, Iowa and Nebraska Railway. The Fairbanks scales in great variety, both of size and purpose, and of a finish and an accuracy which have become proverbial; the Howe scales; the Goodyear boot- and shoe-machinery; Stow's flexible shaft; Lechner's coal-mining engine; Allen & Roeder's riveting-machine; and Delamater's punches and shears,--are a few more of the representative machines. Sewing-machines are not in as great variety in the American section as they were in Philadelphia. There are, however, enough of American and European to foot up about eighty exhibitors. Wheeler & Wilson's have been awarded the grand prize, and there are various medals for others, both home and foreign--the American machine, Cole's and Wardwell's among the number. The various hardware exhibits, such as the Disston saws, Ames shovels, Collins axes, Batcheller forks, Russell & Erwin builders' hardware, as well as the Remington, Colt, Winchester, Sharpe and Owen Jones rifles and revolvers, and the Gatling and Gardner guns, are a little on one side of my present line of subjects.
