THE LOOMS.Just after entering the main haU, are four rery interesting machines, on the left. The tiro first are the looms which are manufacturing jeans, and such fabrics as are not often produced. They are making jeans into every Inch of which two hundred threads are pounded. It makes a cloth that hardly discloses the thread, so close is the fabric. Don't stand off too far, for you are in the presence of that which would produce astonishment to many a manufacturer. Stoop down and look at the goods, for they are remarkable of their kind. Ask questions of the gentlemen having them in charge, and they will be glad to tell you what they are. Yet a little farther to the left is an ingenious machine for weaving In plaids and diagonals. It is in motion much of the time, and hundreds gather about it, as the ingenious msehtaery day by day produces the results which years ago the hand might alone have expected to accomplish.Then farther down the aisle is a hand loom. They are, usually, making jeans—and the work is done by turning a crank. We owe it, however, to the manufacturer to eay that he does not regard it as hard labor as turning a grindstone, though the process looks much like that.A SEA TURTLE.A novelty was added to the basin of the fountain yesterday, by Charles C. Deininger, in the shape of a sea turtle weighing four hundred pounds, which was watched during the afternoon and evening with considerable cariosity. He did not appear to be specially moved by the change he had undergone from the dry air of the railroad car and the express wagon to his mdre natural element. Perhape It was because he thought there should be a little salt added. At any rate he was very quiet, only sl owing a few inches of his huge shell to be seen.EXHIBITORS’ MEETINGS TO-DAY.The exhibitors from class 2 to class 12, inclusive, will bold meetings to-day for the purpose of selecting one from each class to eerve on the Premium Committees:Class 2, at 9 A.M.; class 3, at 9% A.
