If You Don't Smell All Right in a

Bee-Hive, You're Kicked Out

ALL bees smell alike to average mor- l\ tals, but Dr. N. E. Mclndoo, whose book, "Recognition Among Insects," has recently been published by the Smith- sonian Institution, has trained his nose until he can recognize the three castes of bees — queens, drones and workers — merely by smelling them. He can also dis- tinguish several other odors peculiar to bees and their hives. His experiments show that the bees themselves recognize one another by individual odors, and use the sense of smell for as many purposes as human beings use their eyes and ears. "Worker bees returning to the hives from the field pass the guard unmolested, be- cause they carry the proper sign, although the hive odor they carry is fainter than when they left the hive, and it is also partially masked by the odors from the nectar and pollen carried by these bees."

���A Noose Used Not for Hanging But for Life-Saving

JUST escaped, perhaps, from danger, the half-dazed fire victim often finds descent all but im- possible.

To make this de- scent safer, Hulda E. Astarita, of Brooklyn, NewYork,haspateni;ed a new device. It is a simple, swinglike seat with a footboard at- tachment. The parts are held together by ropes, and an extra loop of rope is at- tached, noose fashion to both sides of the carrier about midway between the seat and the top.

This loop of rope is slipped over the head and allowed to tighten itself about the upper part of the body. Any pressure on the foot- board serves to tighten the rope more securely about the body.

Coat Tails Into Trousers Free Movement

THE new coat shown in our illustration affords closer protection for the legs, inasmuch as it can be buttoned tightly around them. This ar- • rangement prevents the flapping of the tails of the coat and makes walking or even running much easier. The new model also per- mits the wearer to crawl without difficulty and thus makes itself valuable in the trench style of war- fare. A further use of the new coat is that it can be made to fit comfortably into the high rubber boots worn in the trenches, thus preventing it from slop- ping in the mud.

When the overcoat is not buttoned about the legs, it presents nothing unusual in appearance, closely resembling, in fact, the ordinary models.
