' I 'HE indispensability of rubber in some industries was 

 *■ strikingly demonstrated at the Electrical Exposition 

 and Motor Show, held from October IS to 25 at the Grand 

 Central Palace, New York. 



In nearly every exhibit success was dependent on perfect 

 electrical insulation ; and this, in almost every instance, was 

 based on the use of rubber, so that while the substance was 

 only conspicuously in evidence in a few cases, its importance 

 was revealed by even a perfunctory inspection of the many 

 ingenious contrivances shown. 



Particularly dependent on rubber for its efficiency was the 

 De Laval nieclianical milker, made by The De Laval Separator 

 Co., New York, and shown in operation at frequent intervals, 

 thanks to the co-operation of a herd of beautiful Ayrshircs. 

 The device that held the cow's teats and replaced the hands 

 of the human milker was of rubber, as was also the tubing 

 that connected the milker with the cushion apparatus and 

 that by which the milk was delivered into the pail. 



As serving to emphasize the versatility of rubber, there was 

 also an exceedingly compact sending and receiving outfit for 

 a field system of wireless telegraphy in the interesting exhibit 

 of the Signal Corps of the United States Army. Contained in 

 a receptacle resembling in size and exterior appearance a 

 small dress-suit case, it was not only complete and admirably 

 executed from a mechanical point of view, but it formed a 

 practical illustration of the value in such an apparatus of 

 hard rubber as an insulating material and the skill with which 

 it is utilized for this purpose. 



The well equipped hospital, supplied with all the parapher- 

 nalia for surgical work, the making of radiographs and the 

 hygienic care of patients, was a rubber triumph. In every 

 transformation to which it is subjected by the manufacturers' 

 treatment, uses had been found for rubber, and modern sur- 

 gery seemed to owe no small share of its marvelous success 

 to the intelligent adaptation of rubber to the wants alike of 

 surgeon, patient and attendant. 



The National Bureau of Standards, a branch of the De- 

 partment of Commerce and Labor at Washington, which 

 makes scientific tests of the tensile strength of rubber, rubber 

 goods and fabrics entering into them, of the elasticity, re- 

 siliency, chemical properties and electric insulating efficiency 

 of rubber, was also represented. 



A full sized working model of the "fighting bridge" of a 

 battleship was the contribution of the navy to the exposition ; 

 and the importance of India rubber as an insulating material 

 for the delicate electrical apparatus installed on these great 

 masses of steel possessed particular interest, even for the non- 

 technical observer. 



The electric motor vehicle was given a prominent place. 

 Besides a demonstration track, a fireproof model garage was 

 set up on the third floor of the building. It was fully equipped 

 with electrical vacuum cleaners, tire pumps, car washing ma- 

 chines, battery charging boards and rectifiers, including a 

 battery room and repair shop fitted out with the latest elec- 

 trical appliances. In nearly all of these rubber plays an 

 indispensable part, for where it is used no material has yet 

 been found to take its place. 



SAND AS AN ANTI-SKID. 



A company has recently been formed in Detroit, Michigan, 

 which has as its object the promotion of the sale of a device 

 which will prevent automobiles from skidding, this result being 

 attained by sprinkling sand on the rear wheels. The company 

 is known as The Auto Sand Grip Co., and the officers are: 

 J. F. Williams, president; P. G. Sanderson, vice-president; 

 C. B. Shotwell, secretary and treasurer.
