INVENTION AND DISCOVERY.

By means of slot-boxes one may buy gum or postage-stamps, be weighed, or

have his picture taken.

A schoolboy of St. Louis has recently invented a new and practical form

of this popular machine.

The Martin paper slot-box is to be used upon street cars and railway

trains for the sale of daily papers.

It has separate compartments for each morning daily, with movable

name-slips so that the one box may serve for the sale of both morning

and evening papers.

Though small and neat, the box will hold forty-five papers.

By inserting a penny and pushing a button, any paper desired may be had.

The boxes are so arranged that five cents will be necessary to work the

button for Sunday papers.

The patent papers have been received, and the youthful inventor is

superintending the making of the boxes. As soon as a sufficient number

are ready they are to be given a thorough trial on the leading lines of

cars in St. Louis.
