The machine is easily moved from tree to tree and has a small, portable boiler which car easily be moved about by one horse and can be kept stoked by the men operating the tree feller.

A HANDY SHOE BRUSH ABOOT brush that contains the paste, brush, and polisher in one device is a handy innovation for the household or business office. The under side of the brush is divided into two parts. One holds the bristles with which to apply the blacking and rub it on the shoe and the other half holds the device for polishing the shoe. Under the cover is a receptacle for the blacking, which is applied to the shoe by turning a key, conveniently placed in the side of the brush. When the tube of blacking is exhausted the cover slides back and a new tube is inserted.

From two to forty sheets can be bound securely together, without any adjustment of the machine, by pressing the lever down sharply. A AN IMPROVED PIE PLATE NEW plate for baking pies consists of two pans both perforated, one inside the other. The advantage of having two pans lies in the fact that the crust of a pie thus baked will be of an even thickness throughout and the plates, being perforated, permit of a free circulation of air, so that the botto crust need no longer be soggy and heavy, as is often the case in pies baked in the ordinary manner, but can be baked as light and flaky as the top crust. A AN ACCIDENT PREVENTER MEANS of protection for workers on presses has recently been devised by the use of an easih adjusted little lattice-work gate which lets down when the operator throws the clutch in to operate a press. Except for a brief instant between the pressing of the treadle and the tripping of the press the gate never interferes with the workmen and, being made like a lattice, the operator sees through it clearly at all times. The moment the work is completed the gate springs back to a folded position out of the way. is to be operated OUR ARMY AND NAVY IN THE WAR HOW WE CAN BEST HELp the allieS (Illustrated) FLYING FOR FRANCE (Illustrated) 476 485 JAMES R.
