V. Rickenbacker, Uncle Sam's famous ace of the world war. This new model of motor car, it is predicted, be made folding wings, so that on a straight stretch, of road they can be spread and the machine will take to sir. The present-day tendency to lighten the construction of automobiles through the extensive use of aluminum alloys, without sacrificing the safecy factor, and the great progress made in airplane construction as the result of recent experiments with motorless gliders, as weE as motor gliders, are the two factors that make this possible.

To overcome this, a new type of milk bottle has been designed. At the lower the bottle is pierced with a large hole: and around this hole is placed a circular shoulder of glass.

The hole 11 this nipple is smaller, even, than that through the baby is accustomed to get his milk; and the exposed inside of the nipple is filled witk clean cotton.

It is claimed envelopes were ased in Frasce before they were introduced in England, and there seems to be good ground for the claim.

Whea they first came on the French market they very dainty novelties ind were made from the most expensive and delicate papers. They were used only by the wealthy, and were considered a fad. They were used by the public in England in a limited way between 1S30 and 1839. It has been claimed that about 1830 a bookseller in Brighton, England, by the name of Brewer, made envelopes by hand, the action of germs in the incoming- and thai he was the first manufacturer of envelopes; but there are quite a number of others who claimed to be "Srst" in this including manufacturers in New- York, Boston, Philadelphia and Louisville. However, there is no one KOTV living who can testify on the subject, and no authentic records are for proof.
