On the inside of the strap is some flexible air-tight material partly fastened to the strap, and so arranged that it will entirely cover the lips of the wound.
The edges are covered with adhesive material, and are firmly pressed on either lip of the wound, drawing it together and covering it with air-tight material, so that no air can escape.
The strap is then buckled round the tire, holding the ligature in place, and the air can be pumped in and the rider proceed without fear of any further difficulty.
Bicycle Propulsion.—So much has been invented for and said about bicycles, that it seems strange that anything is left to say or to do, yet here is a very novel idea. It is not so very long since wind and water were the only motor powers, but those days are so clearly superseded that it is quite a surprising suggestion that a wind-wheel be attached to bicycles. Machinery connects it with the driving-wheel by means of a rotary shaft, and the wind-wheel becomes an additional help. This may prove a very useful contrivance for long-distance riders.
Embroidery Hoop.—There are surely among our readers some girls who embroider and who have experienced difficulty with their embroidery hoops. The inner hoop is sure to fit so tightly within the outer one that if the material to be embroidered is at all thick, neither persuasion nor force will make it slip into place. A new hoop is now being made which can be adjusted for goods of any thickness. This is done by means of a split binding-hoop, the two ends of which connect by a screw-threaded bolt, and can be loosened or tightened at will, a nut on the threaded end of the bolt holding the ends firmly in place.
