century, and, as a result, New Jersey was
in a position to illustrate to younger and less thoroughly studied
States how science and industry go hand in hand.

New Jersey is the best-mapped portion in America. Therefore a salient
feature of the exhibit was a large relief map of the State, models of
typical sections of the State, and files of the position and elevation
of every portion of the State. The building stones of the State formed a
pyramid in the center of the exhibit, and alongside of it was a
microscope, with 70 sections of New Jersey rocks, showing how they are
studied to estimate their value for construction purposes.

The New Jersey geological survey had two superb terra-cotta columns made
of New Jersey clay on enameled brick piers. Adjoining the entrance was
the New Jersey clay exhibit proper. In it were shown samples of all the
prominent clays, burned bricklets, which illustrated the way clay acts
when burned at various cones (temperatures), the air and fire shrinkage,
and various other properties and analyses of clays, all facts of
importance to the clay worker, as well as large photographs of the chief
clay banks and various steps in utilizing clay.

A collection of New Jersey bricks was tested to determine the breaking
and crushing strength. The results of these tests were shown, together
with samples of the bricks classified according to the method of
manufacture and geological occurrences of the clay. A model of a New
Jersey clay refinery was shown, illustrating the manner in which
high-grade clays are prepared for potteries.

The natural advantages found on the coast and mountains of New Jersey
have produced many fine and well-known resorts. In order to illustrate
some of the attractions there found, the exhibit in the Forestry, Fish,
and Game Building was prepared. It showed beautiful mounted specimens of
practically all the birds that frequent the State. In addition to the
mounted fresh and salt-water fishes there was displayed, in the largest
pool that has ever been constructed at an exposition, a number of the
live salt-water fish found along the coast. The oyster industry was
represented by an exhibit from the State bureau of shell fisheries. A
glass tank filled with salt water showed an oyster bed containing the
following variety of oysters, all of which are products of New Jersey:
Shrewsburys, Raritan, Barnegat, Maurice River coves, Absecon salts, and
the Cape May salts. The tank also conta
