��Making Artificial Cream That Rivals the Original

WITH natural cream at thirty-five cents a pint, it is now cheaper to make your own cream. Two Chicagoan chemists have discovered a process whereby the supply of skimmed milk ma>' be converted into cream. Some sugar is first dissolved in the milk. Lecithin, a substance obtained from the yolks of eggs, is mixed with melted beef or butter fat. The two mix- tures are then poured into a pot and heated and thoroughly whipped together. When a uniform, creamy mixture has been obtained, it is pasteurized, cooled and set aside until wanted. The result is a readily digestible and a highly nourishing cream.


��Like a Combination Tool Is the Blood- Sucking Apparatus of the Horsefly

WHEN a horsefly aHghts on a horse, he walks around looking for a tender spot, and this lie finds with his hairy feelers. Then he cuts a hole with the scissors shown on each side of the central tubular tongue. An ordinary lead pencil cannot be sharp- ened to a point without sharpening the lead. So it is with the tubular end of this tongue-like ex- tension of the horsefly. Na- ture has provided it with barbed, piercing "derrick ropes." The fly inserts these sharp points into the horse and then pulls back on them. The

��This is the business end of a horsefly — a wonderful combination tool consisting of scissors, piercing barbs, and a sucking tongue

barbs hold and the fly's tongue is forced down into the horse's flesh. But if the hole has already been made, then it is not necessan,^ for these elaborate tools to be taken from the sheath in which they are placed within the tongue or proboscis. The blood is sucked up by the tongue in practically the same way as by other forms of flies. — Edward F. Bigelow.


��The crown and brim are separable and the brims are interchangeable. Four snap-fasten- ers are provided for joining the two sections together

��Two Hats with but a Single Crown and but a Single Cost

EHOLD! The hat problem— or one phase of it — has been solved. The ingenious young woman on the left can ha\-e a large-brimmed hat or a short- brimmed one, according to her personal taste or to the need of the moment, simply by ad- justing the crown over the brim she prefers and snapping the fasteners. If she is going for a tramp in the sun, her broad-brimmed hat will be re- quired: but if she is to travel through New York cit>' in the subway during the rush hours — presto! a change is made. The idea is capable of a number of variations. With separable frames of buckram or wire for both crown and brim, any number of coverings may be used with varieties of trimrnings, and such a wealth of headgear will result that one's friends and even one's family may be mystified as well as delighted.

Needless to say the initial cost of the original hat-and-a-half is nominal, con- sidering the multiple duty to be performed.
