BATHING WITH MOTOR TIRES. 



[from "the new YORK TIMES."] 



A NEW bathing fashion has been started at Ostend by a 

 ^ ^ chauffeur who, dressed in scarlet and with a Phrygian 

 cap, entered the sea with the inflated inner tube of a motor 

 car tire. First he trundled it as a child does a hoop. Then 

 sitting on it as in a life buoy, he paddled about, propelling 

 himself with his hands or lay basking in the sun. His enjoy- 

 ment was so manifest that in joke a party of women swim- 

 mers borrowed the tire and, with shrieks of laughter, imitated 

 his antics. The idea has taken and scores of persons now dis- 

 port themselves in the sea on the tubes of their motor cars. 

 Impromptu races attract many competitors, and not to take a 

 tube sun bath is to be out of the mode. 



[from "the new YORK EVENING JOURNAL."] 



A TKETTv young guest at the Hotel Nassau, Long Beach, is 



responsible for a new fad uliich became immediately popular 

 after her introduction of it at that beach resort, and has now 

 spread to several of the beaches along the Jersey coast. This 

 fad is bathing with the aid of the inner tube of an automobile 

 tire. 



The lady heard of the fad from a friend abroad who saw it 

 first at Ostend. .-X cliauffeur started it there. It consists in 

 using the rubber tube, inflated, as a kind of life preserver and 

 seat combined, with which it is possible to float about on and 

 over the combers as they roll shoreward. 



The practice has become so popular that now along the shore 

 at Long Beach any day during the bathing hour young men 

 and women may be seen floating about atop these automobile 

 tires, mounting and descending the huge wave? and having a 

 vociferously good time generally. 



NOTES ON A VISIT TO AMERICA. 



BY PHILIP SCHIDROWITZ, PH. P. 



r\URING a recent visit to America I had the privilege of 

 ^-^ seeing a number of leading factories and also some of 

 the chief government institutions. I was much struck by the 

 cordial and open manner with which I was received in the 

 various works and by the ready permission granted to inspect 

 practically anything that I wished to see. It was impossible not 

 to contrast the American methods in this regard with the ultra- 

 conservatism displayed in so many of the European works. Nat- 

 urally, however, most of that which was of particular interest, 



1 must regard as "not for publication," or I should be making 

 a poor return for the great courtesy displayed. There are a 

 few points on which it will not be amiss, I believe, to make 

 some comments. 



Raxv Material. — I was astonished at the apparently very large 

 quantity of guayule employed in the American works. Most of 

 it seems to be in semi-purified loaves, containing 20 to 30 per 

 cent, of resin. There is also a commercial article purified to 



2 to 3 per cent, of resin, but I did not come across much of this. 

 It will be of interest to people on this side to know that rub- 

 ber manufacturers in the United States are very favorably in- 

 clined to the better qualities of clean plantation rubbers or to 

 rubbers prepared on the plantation system. I came across a 

 good deal of Ceylon and Malay Hevea and also some fine Fuii- 

 tumia from LTganda, which were all well liked. A complaint 

 was made regarding some of the Eastern rubbers which I think 

 deserves the attention of planting companies, and it was that fre- 

 quently numerous bits of bark, twigs, etc., are found between 

 the biscuits, crepe and sheet. This involves washing, which 

 operation, for this class of raw material, should be quite un- 

 necessary. I need scarcely say that I am not referring to "bark 

 scrap." What is required is a little more care in packing. 

 American manufacturers, like their English colleagues, are verj' 

 emphatic on the point that planters should mark all their goods 

 in some simple fashion, as this enables the manufacturer to 

 know exactly what he is buying — a matter, in view of the con- 

 siderable diff'erences between various plantation rubbers, of some 

 importance to him. Certainly there is a very large field in the 

 United States for the plantation product. 



Finished Goods. — For obvious reasons, I cannot refer to de- 

 tails of manufacture, but speaking generally, I think I may say 

 that there is a tendency on the part of the American manufac- 

 turer to work for greater mechanical strength than is general on 

 this side. The reason, I believe, is that "tensile" tests in con 

 tracts are much more common than in Europe. 



In conclusion of these brief notes, I should be glad of the 

 opportunity of expressing my thanks to the various manufac- 

 turers, oflicials and others in America for their great courtesy 

 and hospitality to me during my stay. — Tin- hxdia-Rubher Jour-
