EXPERIMENTS ON THE RESISTANCE OF

ADAMS, NEWPORT HARBOR, UNDER THE
DIRECTION OF COL. TOTTEN.–BY LIEUT.
T. S. BROWN, OF THE CORPS OF ENGI-

For the purpose of examining further the degree and nature of the resistance offered by sand when it is attempted to force it through a tube by direct pressure, the

2 following apparatus was arranged, after a a few preliminary trials, which had given some idea of the power it would be neces. sary to apply. A side and end view, and a plan of the apparatus are given in the cut on the next page.

The strong cast composition tube, a, about fifteen inches in length, which contained the sand, was held in a vertical posi. tion by being passed through the block, c.The pressure was always applied to the bottom, and the collar, b, cast upon the tube, prevented its being forced upwards. The block c, was secured in iis place by being let into the four pozis, 1, 2, 3, 4, passing from the floor to the ceiling. These four posts formed a very stable frame work, and between each pair, the space, g, permitted the sliding board, e, to move freely up and
