bands, applied by means of machinery, and gradually increas- 

 ing in size with the growth of the core. The number of such 

 bands used in the construction of the specimen ball shown was 

 306. This construction gives the Davis ball an ele- 

 ment of novelty as compared with other rubber 

 cored balls, and it is stated that the method of 

 manufacture is more clearly pointed out in the 

 specifications of another patent now pending. It 

 seems proper to state, however, that the description 

 which The India Rubber World is asked to cor- 

 rect was based upon the following paragraph in the 

 original patent [No. 697,816] : " In the form of 

 device shown in Fig. 3 the inner shell A, which 

 may be of steel or celluloid, as before, is separated 

 from the outer Gutta-percha shell B by a shell C, 

 composed of a number of layers of fine rubber 

 stretched on under tension." In another paragraph 

 the inner shell is referred to as being " wrapped 

 around with the rubber strands." We are willing 

 to admit, however, that these expressions do not necessarily 

 imply that the rubber is "wound on under tension." 

 THE PNEUMATIC GOLF BALI.. 

 This ball, already referred to in this paper as the invention 

 of Addison T. Saunders, is now being marketed. In size, 

 weight, and appearance it does not differ from other balls, 

 though in construction it consists of a hollow sphere filled only 

 with compressed air, which the inventor has chosen as the best 

 resilient known. The shell of this ball is designed to be practi- 

 cally rigid under the light impact of a putting stroke, but de- 



of frames of galvanized iron, with bearings of bronze metal ; 

 the pressure is applied through steel springs. The smaller of 

 the three sizes mentioned weighs 200 pounds, and is designed

pressible under heavier blows, thus bringing into action the 

 resiliency of the compressed air. " The weight giving portion 

 of the Pneumatic ball," it is stated, " lies away from the center ; 

 hence a given degree of ' undercut ' in a stroke gives the Pneu- 

 matic more 'underspin' than it does in a solid ball." By a 

 well known natural law, this rapid rotation holds the ball true 

 to its course and increases its "carry." The method of con- 

 struction was detailed in The India Rubber World, October 

 1, 1902 — page 17. [The Goodyear Tire and Rubber Co., Akron,

POWER WRINGERS FOR LAUNDRIES. 



The employment of rubber rollers for laundry purposes is by 

 no meams confined to the hand operated clothes wringers 

 with which every one is familiar. Power wringers are made in 

 considerable numbers, for use in the larger laundries, and an il- 

 lustration herewith shows the mounting of a set of rubber 

 rollers for such a machine, manufactured by the Troy Laundry 

 Machinery Co., Limited (Troy, New York). The machines 

 made by this company are of three sizes, calling for rubber 

 rollers 3^ inches in diameter, and iS inches, 24 inches, and 30 

 inches in length, respectively. These power wringers consist 



1 iisoN 



for 40 revolutions per minute. The rubber rolls are made by 

 the American Wringer Co. 



"PETITE " ANTI COLIC NIPPLE. 

 There is now being offered on the market, in a special small 

 size, the well known " Ami Colic " nipple manufactured by the 

 Davol Rubber Co. (Providence, Rhode Island). The idea of a 

 small size nipple of this type was suggested by the 

 management of the celebrated Sloane Maternity ? 

 Hospital, in New York. In that institution not a S 

 few incubator babies have to be cared for, and %, 

 the regular size nipples sometimes were found to ! | 

 be too large. Hence the new article, which has 

 been termed the "Petite" Anti Colic nipple No. 

 247. The regular size is No. 147. It has proved popular al- 

 ready, not only for the purpose for which originally intended, 

 but for "regular" babies as well. A special feature of con- 

 struction of these nipples is the " ball top," and another is the 

 three small holes (instead of the usual one hole), which gives a 

 natural flow of milk. These features are protected by patents. 



BAILEY'S "PETITE" COMPLEXION BRUSH. 

 The daintiest article that Bailey has yet turned out is his 

 "Petite" brush made of red rubber about half the size of his 

 regular brush, and put on the market for half the price, which 

 is 25 cents. That the brush is exactly what the trade called for 

 is proved by the great number of rush orders that have been 

 sent in since the first samples were shown. [C.J. Bailey & Co., 

 No. 22 Boylston street, Boston.! 



THE "SEARCHLIGHT" PACKING. 

 A new white packing that is growing in favor daily is that 

 which has been put on the market under the excellent name 

 "Searchlight." This packing was not marketed until it had been 

 tested exhaustively for a year and a half. It is designed for high 

 pressure steam, for oil and for similar work. It is pure white 

 and beautifully finished. [The Republic Rubber Co., Youngs- 

 town, Ohio.] 



At the thirty-first annual meeting (London, [uly 6) ol the 

 Amazon Steam Navigation Co., Limited, the accounts presented 

 showed a favorable condition of business ; net profit for the 

 year 1902 of ^19,211 19s. iorf., and recommended a final divi- 

 dend which, added to the distribution six months before, made 

 a total for the year of 4 per cent. The company own 33 steam- 

 ers, operating on the Amazon and its tributaries, and also hold 

 shares in two ocean steamship companies and in the Manaos 

 Harbour, Limited.
