The new brush is so arranged that it does not touch the mucilage, but is held above it by a spring in the handle. When the gum is to be used, the top of the handle is pressed, and the brush is forced down into the bottle until it meets the liquid.
The moment the finger is taken off the handle, the brush springs back into place; and when taken out of the bottle it is found to be furnished with a metal rim which prevents any of the liquid from touching the fingers.
We have chronometers which can register time, and odometers which can register distance, but there has been the double weight to carry of the two instruments; and, while every effort is being made to reduce the weight of the bicycle as much as possible, every ounce or fraction of an ounce tells. Consequently all cyclists are indebted to the man whose happy thought it was to combine the two, and who had the skill to do it. An instrument can now be had which will at one and the same time register time and distance.
Something new which will surely find favor with bicycle riders is a simple coupling apparatus by means of which any two safety bicycles may be converted into a tandem. We see so many bicycle tandems in the parks and bicycle paths that riders will surely be glad to know that any two people can have a tandem at a moment's notice, and at the same time, if one person only wishes to ride, the machines can with equal speed be restored to their original condition.
