THE BRIDGE OF KNIVES.
Place three glasses, A A A, in the form of a triangle, and arrange three knives upon them, as shown in the [figure],—the blade of No. 1 over that of No. 2, and that over No. 3, which rests on No. 1. The bridge so made will be self-supported.
THE TOPER’S TRIPOD.
Place three tobacco-pipes in the position shown in the engraving, the mouth of the bowls downwards, and the lower end of the stems upon the stem just by the bowls. This tripod, if carefully put together, will support considerably more than a pot of “Lockwood’s home-brewed,” equally celebrated with the trick.
