tles of cold water, milk,

LEAK-STOPPER FOR PNEUMATIC TIRES.--This seems to be a very clever and
practical invention.

The bicycle-tape, and the mastic, and the dozen other devices for
mending punctured tires are all very well in their way, but they are not
absolutely reliable.

A punctured tire is a wounded tire, and needs the aid of a bicycle
doctor. All attempts at doing one's own surgery are likely to fail for
the simple reason that we are not experts in the business, and do not
always understand the extent of the damage.

The leak-stopper is merely a bandage to be applied to the wound till
help can be found. It consists of a strap of flexible material, provided
at one end with a buckle and at the other with a pair of tongues.

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superseded that it is quite a surprising suggestion that a wind-wheel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
