���While the condemned horse eats, the gas enters the air- tight stall, causing him to die peacefully and painlessly

��A Humane Method of Destroying Horses with Illuminating Gas

ANEW equipment for killing con- demned horses with illuminating gas has been installed in the Denver City Pound. A small air-tight stall is connected with the city gas - main. While the horse is munching his oats or hay from a mangei in one side of the stall, the gas enters from a pipe directly underneath. The animal gently and peacefully subsides into insensibility.

The stall is ten feet long, seven feet six inches high, and four feet wide. It was devised by Walter C. Cox, of Den- ver, Col., who claims that stables or buildings can be adapted to the purpose by making them air-ti;.ilit. He has also devised a leather inhaler with a three quarter-incii hose connection and a strap to pass around the horse's nose. The inhaler is used where a stall is not available.

��b\- the use of an adjustaliie weight. But the apparatus for suspending the weight is novel. An o\'ershoe-form is laced' over the foot. To this overshoe straps are attached which run over rollers mounted in slots in the upright end-board of the frame. These straps are attached to the weight - strap, which runs up over a roller suspended from a scale. The other end of the strap has a weight attached to it.

Movement of the limb up or down or longitudinally within restricted bounds is possible, as in doing so the suspended weight is raised or lowered without altering the tension on the liml). This alleviates the discomfort, to some degree, of a trying situation. The sides of the apparatus are hinged to permit of the letting down of either side in order that the limb of the patient may be placed in it easih-, as shown in illustration.

��New Apparatus for Setting Broken Bones

Tins apparatus for setting broken leg Ijones, devised by John B. Hunt, Mansfield, Ohio, makes it possible for the patient to move the injured leg to a limited extent without danger of displacing the fractured ends. The bones are kept in correct alinement, as is customary in surgical practice,
