��The method of procedure in excavating, as described up to this point, has been in the direction of the width of the new structure, but with the "runner" beams in place, the work progresses in the di- rection of these beams. As fast as the rock is removed beneath the "runners," posts are placed to carry the free end and, with the other end supported on the original rock, the remaining foundation can be removed with little danger to the subway overhead.

The new structure is next completed, whereupon all temporary shoring and supports are removed and the subway above is restored upon the roof of this new work, filling all voids between the two structures with masonry. It goes without saying that the work is carried on from the adjacent unfinished portion.

This Tobacco Pipe Is Built Like a Cornet, But Isn't Musical

A TOBACCO pipe of unusual design has been invented by Warren Mur- ray Baechtel, of Hagerstown, Md. Every pipe-smoker knows that the longer the stem of his pipe the cooler will be the smoke. Pipes with stems a few feet long have been in use in different countries for many years, but their awkward length precluded their use outside of the house. The inventor of the pipe shown in the illustration circumvented the difficulty by coiling the stem of the ^^ pipe like the tube of a cornet or signal horn. The coils are connect- ed at their low^er end to form a dripping - chamber for receiving the saliva which accumulates in the stem. Each coil has an independent open- ing into the dripping-cham- ber and a screw cap at the bottom gives access to it for the removal of the ac- cumulated saliva. The smoke, in passing through the coils of the stem, is drained several times of saliva and nicotine.

A Baseball Base Which Moves When It Is Hit

���The long, coiled stem, without being awkward, insures a nice cool smoke

��N improved baseball base, which is anchored to the ground so that it is secure and yet is able to yield, has been invented by Sydnor M. Falconer, of Washington, D. C. Bases, as they are now fastened to the ground, are often torn from their moorings, or they are so immovable that they injure the player when he strikes them at great force. The base described is provided with a coiled spring, which enables it to move slightly from its anchored position and thus pre- vent the player from getting injured. When released, the base returns instantly to its former position.

When a base-runner ccmes sliding, hands first or feet first, with considerable speed against an immov- able base, he is very apt to sustain a sprain or other serious injury. This device should therefore appeal to those players whose ambition frequently makes them risk their • limbs in the base stealing of bases. A similar de- vice, which would make the football-player's anat- omy bend instead of break on contact, is desirable.
