It Is Almost Impossible for You to Lose This Hand -Bag

ANEW YORK man has invented a sim- ple device which should be a boon to careless women, as it prevents. the loss of the hand-bag. The leather handle is fitted with two metal slides on one end of which is a roller. These slides are fitted to the handle straps and are connected by a short piece of leather of the same width as the handle.

When the handle is slipped over the arm, the metal slides are pulled up b^'- the weight of the bag so that the handle fits close around the wrist and makes it impossible for the handle to slide over the hand.

This is only one of many devices which have been invented and placed on the market recently for the purpose of helping women to hold .on to their purses, which are so easily lost in crowds.

The av-erage man is doubtless more inter- ested in probable means of persuading them (at least those of his own immediate family) to keep possession of the contents of the purses a little longer.

��Consider the Cow. She Helps Make Buttons and Shoe Polish

WITH no apparent effort the cow goes through her span of years yielding her full quota of milk and look- ing always as if she could impart great secrets to the world if she had the gift of speech. She is an industrial asset, not a mere purveyor of baby food. It has been proven that casein, which forms over three per cent of the total weight of cow's milk, is an important commercial product and may be profitably employed in the manufacture of glue, combs, but- tons, linoleum, hair-pins, toys, paints and even shoe polish.

In the preparation of casein for com- mercial purposes, about seven hundred gallons of skimmed milk are put into a great vat and heated to about one hun- dred and thirty-five degrees, Fahrenheit. Then very dilute sulphuric acid is added to precipitate the casein or curd. The whey is drawn off and the curd is drained and cut into chunks, after which streams of cold water are played on it to wash out the acid. The curd is then dried with rotary fans and ground into powder, in which form it is placed on the market. One hundred pounds of skimmed milk will yield about three and one-half pounds of casein powder.


��Saved by the Bullet Intended to Kill Him T is better to be born lucky than rich, they say, and no doubt a certain policeman of Alton, 111., will sanction the sentiment. He was one of a squad sent recently to arrest two desperate

��criminals who had been located hid- ing in a boarding house. When cor- nered, one of the men at bay press- ed the muzzle of h is revolver against the policeman's abdomen and pulled the trigger twice in rapid succession. , The first bullet rammed in the barrel about an inch from the cylinder. This effectively barred the pathway of the second shot, the force of which tore a strip from the barrel an inch long through which the bullet escaped, thus destroying the usefulness of the weapon.
