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. 



SCISSORS 

 C3 CENTRAL TUBULAR TONGUE 



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.
