Mike Has a Nose of Brass, But He Should Worry

IT IS being demonstrated to the folks of Mt. Healthy, Ohio, by old Mike, the faithful horse of the street-cleaning department, that a real nose is quite a superfluous thing.

Now if Mike had relied on his own natural nose he would have been dead long ere this.

When Mike's nose ceased to work prop- erly some five years ago, and it seemed that Mike would die of suffocation, Joe Stoppel, his owner, said it would be a shame to let a nice horse like Mike go to the dogs merely because he hadn't the use of his nose.

So Stoppel consulted a horse doctor who told Stoppel to cease grieving, because he, the doctor, could give Mike a new nose by way of his neck.

The doctor made a hole in Mike's neck and opened the windpipe and put a tube into it. At the outer end of the tube he fastened a brass disk which may be seen in the picture.

All the air Mike breathes goes through the disk, up the tube and down Mike's windpipe. On cold days Mike's brass nose even emits steam.

"And he's better'n ever now," says Stoppel. "Giddap Mike."

In contracting the stack from a diame- ter of ten feet, six inches at the base to six feet, ten inches at the top, the sec- tions were tapered in a novel manner. In the form were a number of tapering slats. The sections were made smaller and smaller by re- moving one slat from the form each time a section was laid.

The engine room likes the improve- ment. Almost always engine rooms are the most poorly venti- lated regions in a whole building. We anticipate there'll be a big rush of en- gineers to Los An- geles, now that we've published this article.

��Carrying Off Smoke and Foul Air in the Same Smokestack

A DOUBLE-WALLED stack, which acts as a combined ventilator and smokestack, has been built in Los Angeles, California. The foul and hot air from the engine room enters at the bottom of th2 stack, passes up through a sjnicc be- tween the outside concrete wall and an inner firol)rick wall and out of ventilators. The.se ventilators resemble windows and are placed about half-way up the stack,
