Canned Ostrich Eggs May Find a Market in London

SIGNS reading "Newly canned ostrich eggs for sale" may soon meet the eyes of the housewife looking into the windows of grocery stores in London. This statement is based on the fact that ostrich eggs are being packed experimen- tally in South America for shipment to England in liquid form. One ostrich egg is equal to about two dozen hen's eggs. If the canning of these eggs proves successful, it will mean the salvation of the ostrich growing in- dustry which has suf- fered considerably as a result of the war. It will take a large family to con- sume one breakfast egg.

����Kneeling in Cotton Fields Made Comfortable by This Pad

COTTON pickers have to work for hours at a time kneeling upon the damp ground. They suffer tortures. To relieve them, Robert T. Jenney and Rudolph J. Langer of Monticello, la., invented a knee-protector. After the invention was perfected, it became ap- parent that it would be equally beneficial to miners, cement workers, carpenters and gardeners.

The knee-protector is made of strong spring steel. It is just of the right height to place the foot in a restful position. The knee rests in a felt-padded hammock of leather or canvas be- tween the upper arms of the coiled spring while to the lower arms a metal shoe is fastened which is slightly curved upwards in front. The device is fastened to the leg by two straps, one above and the other below the knee. The construction of this humanitarian de\ice is shown in the accom- panying illustration. It should prove beneficial to many workers.

Ride This New Underwater Bicycle —It's Great Sport at the Beach

AT the average bathing Coach about . all you can do is swim, or paddle around in an old canoe.

And so P. Kraemer of Jersey City, N. J., devised the underwater bicycle here illustrated. With this bicycle you can make as much as six or eight miles per hour, which is fast for swimming.

But do you swim on a bicycle? You do on Kraemer's, in a sense, for most of your body is submerged. The submerged fea- ture was especially desired by the in- ventor. He wants you to get the full effect of the water's coolness on a hot day. The two tanks shown are of course filled with air, so as to support a rider of almost any weight. The handle- bars control the rudder. This contrivance should appeal to those for whom ordinary swimming methods are too slow. This aquatic bicycle may make the fish join the birds in wondering where man's encroach- ments on other domains are to end.
