atches was sold within a few weeks after the opening. The latest
improvements in the balance to secure perfect isochronism under varying
conditions of temperature would delight the soul of Harrison, who worked
from 1728 to 1761 on the problem of a compensator for the changes of
rate due to the expansion and contraction of the metal, and received the
reward of twenty thousand pounds sterling offered by the Board of
Longitude.

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.

The United States has preserved its ancient reputation in its
agricultural machinery. We are especially strong in the class which we
term "harvesters," the name including reapers, automatic binders,
mowers, horse-rakes
