l.-mls itself readily in straight effects or to the soft fol(l^ and 

 tuhiess now poiJular in the newest styles. Supple and pliable, 

 with enough resistance to prevent wrinkles, it makes a desiralde 

 material for week-end garments, as it packs snugly without 

 crushing. It can he obtained in a variety of colors, tliongh the 

 black and wliite combination is most popular for single texture 

 women's raincoats, auto coats, travel coats and golf capes.

around which the balloon neck was stretched. A round piece 

 of thin slieet rubber was attached at one point to the inner part 

 of the disk, covering the hole through which the balloon is 

 intiated and acting as an air retaining valve. 



These valves have been almost entirely superseded by the 

 types shown in the illustration, that are interesting developments 

 of the idea to make a cheap and satisfactory valve. 



In the upper row are shown in side elevation three rubber 

 types. Those on the right and left are molded, the one on the 

 riybt being reinforced by a metal ring that is vulcanised in the 

 lower part of the valve body. In both cases the air hole does 

 not extend entirely through the body, sufficient stock being re- 

 tained at the upper end which is afterwards slit, forming a Hap 

 that lifts when the balloon is inflated and closes by pressure 

 from the enclosed air. A pin or match is inserted in the hole 

 in the valve body and the valve raised, when it is desired to 

 ilcllate the balloon. 



.\ novel departure from the usual pmccdure is shown in the 

 upper center view in which a small section of rubber tubing is 

 employed as a closing auxiliary. This is slipped over the neck

.\ British manufacturer of tennis, gynmasiu 

 sporting shoes has put on the market a sanda' 

 children which he calls the "Amphi- 

 bian." It has an open upper, being 

 fastened over the instep by straps, 

 as shown in the illustration. Its 

 distinctive feature lies in its rubber 

 sole, which makes it a comfortable 

 and springy shoe under all circum- 

 stances and enables the wearer to 

 walk over wet grass or moist 

 beaches and still keep dry-shod.

■F. & S. COLONEI.' GOL? BALL 



in the eyes of every |)layer a golf Ijall tliat is long on the 

 'irive, but slow on the putting green ; that tiies fast and far from 

 the tee, but stops dead on the pitch, would be the acme of 

 perfection as an aid to high scoring. The 

 "F. & S. Colonel" ball, evolved after several 

 >ears' experimentation, is credited with these 

 exceptional qualities. It is claimed that the 

 movable center in the ball adds accuracy to 

 its flight when driven from the tee; and on 

 the approach, when given a back-spin, this 

 center revolving against the moinentum of 

 to drop dead, and in putthig makes it as slow 

 a gutta percha ball. The recent patent covering its construc- 

 1 is described elsewhere in this issue. [St. Mungo Manu-

TOY BALLOON VALVES. 



THE manufacture of toy balloons is a highly specialized branch 

 of the rubber business, requiring technical knowledge and 

 special equipment, the successful development of which is due 

 almost wholly to practical experience. There are innumerable 

 types of these attractive toys made in variegated colors and all 

 sorts of shapes, including effigies of various animals, imitations 

 of footballs, watermelons and dirigibles. They are not all 

 equipped with self-closing valves, which feature is a decided 

 advantage as it permits inflation and deflation at will. 



The original type of air valve was a simple disk of wood. 



sk. provided K\{h a hole in the center. Wlieu tlie balloon is 



llated li\ the simple process of applying the lips to the wooden 

 ii.t;. the air is retained by giving the balloon a 

 leu turns to the right or left which closes the neck within the 

 t'lbe section. The air pressure against the end of the rubber 

 tube prevents the neck from untwisting and the air is retained 

 within the balloon. A few turns in the opposite direction will 

 unt\vist the neck and the air then escapes. 



In the lower row, inside views of the metal valves now in 

 use are shown. Tliese are stamped out of sheet tin and are 

 all very similar in shape, size and design although there are 

 some characteristics peculiar to each one which are of sufficient 

 interest to describe in detail. 



The one on the extreme left has a larger air opening than the 

 others and the sides of the disk are straight, and formed with a 

 projecting ear. This is bent down against the round disk of 

 rubber sheet, holding a small section of it against the metal disk 

 while the remaining portion of the rubber disk is free to act as an 

 air valve. 



Jhe next valve is provided with an air opening of about % 

 inch and the edges are beaded, forming a groove to retain 

 the neck of the balloon. A piece of spring wire is given the 

 peculiar form necessary to retain its position within the metal 

 body and at the same tim^ hold the rubber disk in place. 



The third valve shows about the same construction as the 

 jirevious ones, with the exception, however, that instead of a 

 spring retainer a cover is provided and the rubber disk allowed 

 to move freely within the valve body. 



The metal valve on the extreme right retains the same size, 

 shape and general construction of its predecessors but dis- 

 cards all previous methods of holding the thin rubber disk in 

 place. This disk is made very similar to an ordinary pump valve 

 and is held in place by an annular groove on the inside of the 

 \alve body. 



It i~ estimated that there are 20,000.0(10 toy balloon valves 

 made in the L'nited States each vear.
