nntiuns founii in the sbops is a dainty jewel 

 cloth in hght colors. These bags are lined 

 with a fine quality of chamois, to protect 

 the jewels and to keep them clean and 

 bright. The rubberized outer covering is 

 of great value, as it protects the jewels 

 from the moisture given off from the body 

 so continually. IJohn Wanamaker, New 

 York.] 



A "BUNNY" WATER BAG. 



If you want to appeal to a child, do so through its imagination. 

 Children are three-quarters imagination. For instance, a plain 

 hot-water bag doesn't appeal particularly to a child; it is not 

 interested in using it even when its physical condition may ren- 

 der it quite desirable, but convert that 

 water bag into a "Teddy Bear" or some 

 other especially attractive object and the 

 child wants it at sight. Here is a new 

 an<l unique hot-water bag that recognizes 

 that principle. It is called the "Comfort 

 Bunny," and is shaped and covered so that 

 it looks like a white rabbit. It will be seen at a glance that the 

 difficulty would not be to get a child to use it but to get 

 a child to stop using it. [Mistress Patty G. Comfort, .\ndover, 

 Massachusetts.] - _j 



TO CLEAN THE THEE BEFORE TAPPING. 



It is fairly axiomatic to say that the best way to have clean 

 latex is to keep it clean at the start. It is simpler and easier 



to keep it free from dirt 

 than to remove the dirt 

 later. The accompanying 

 cut shows a brush with 

 bristles of iron wire which 

 is very useful in cleaning off 

 the particular part of the rubber tree which is to be tapped, thus 

 insuring a flow of latex free from dirt. [Jean Heybroek, Baarn, 

 Holland.] 



HUBBERSET AND ALBERITE. 



It has been recognized for some time that the vulcanized hard 

 rubber base of the Rubberset brush was practically imperish- 

 able; at least it far outlived the other parts of the brush. Then 

 the problem was to make the rest of the brush as enduring as

the hard rubber base which held the bristles. This quest seems 

 to have been successful, and a new substance has been made up 

 which equals in wear the rubberset base, and is used in connec- 

 tion with it. This substance is called ".Mberite." It is a mate- 



rial similar to solid ivory, takes a very high polish, and is 

 sanitary. 



Two brushes in which this composition is used are here il- 

 lustrated — the complexion and the nail brushes. The first comes

in two styles, and has white bristles, and the second comes in 

 two sizes, has black and white bristles combined, and is guar- 

 anteed indestructilile. [Rubberset Co., Newark, New Jersey.] 



WATERPROOF CASE FOR BITS. 



This is not only a very practical cover but an exceedingly 

 useful one. The case is made of waterproof canvas, with 

 separate compartments for each bit and extra cutter, protecting 



the cuiiiny edges oi both. The inside pocket for the extra 

 cutter keeps it always within reach. It is not liable to shp out 

 of sight, but when wanted can be readily found. [C. E. Jennings 

 & Co., New York.] 



TESTER FOR FLY-WHEEL SPOKES. 



A device for detecting an 

 imperfect flywheel is shown 

 in tlie illustration. It is 

 quite similar to a physi- 

 cian's stethescope and 

 works practically in the 

 same way. The transmitters 

 and receivers are the same 

 as used in the telephone, 

 and the tubing is of rubber. 



It is, in fact, simply an 

 instrument for magnifying 

 sound, so that a dift'erence 

 of sound that would not be 

 perceptible to the unaided 

 car becomes very readily 

 detected. 



The pin in the end of the 

 transmitter is held close 

 against the object to be ex- 

 amined. This instrument 

 is also used to test parts of 

 machines which are in mo- 

 tion but cannot be seen. It 

 has been adopted by the 

 National Tube Co. of Pitts- 

 burgh, Pa.
