TABLE OF CONTENTS ON LAST PAGE OF READING. 



FOREIGN DUTIES ON AUTO. TIRES. 



' I 'IRE manufacturers will undoubtedly be interested in 

 A the table given on later pages in this issue showing 

 the duties levied on motor car tires of every sort in the 

 various foreign countries where tires are used. Naturally 

 the most interesting field for the American manufacturer 

 is Europe. It will be noticed that there is a wide range 

 of imposts on inner tubes and casings in the various 

 European countries. Great Britain of course admits them 

 free. Switzerland follows next with a duty so low — only 

 8 cents per hundred pounds on solid tires and 44 cents 

 per hundred pounds on pneumatics — as hardly to be worth 

 consideration. From this point the duties range upward 

 to that levied by Spain, a country that has no home 

 production to protect but which levies a duty of $23.64 

 per hundred pounds on inner tubes and casings. Next 

 to Spain is Russia, with a duty of $21.39 per hundred 



pounds. But of course in Russia there is practically a 

 government monopoly in the manufacture of all rubber 

 goods. Germany requires a payment of $6.48 per hundred 

 pounds on all inner tubes and casings of foreign manu- 

 facture, while France lays an impost of practically twice 

 that, amounting to $13.13 per hundred pou 



In South America, where one would naturally suppose 

 the importation of tires as an essential pari of trucks and 

 automobiles would be encouraged, the duties run uni- 

 formly high. Paraguay taxes imported tubes and casings 

 at $36.77 per hundred pounds. Chili discriminates be- 

 tween solids and pneumatics, laying an impost of $19.87 

 per hundredweight on the first and $39.74 on the second. 

 Brazil, on the other hand, while permitting pneumatics to 

 enter under a payment of 12.8 per cent, ad valorem, in- 

 creases the impost to 70 per cent, ad valorem on solid 

 tires, which are classed under the general grouping of 

 "rubber manufactures not specified." 



Japan has the distinction of levying the highest specific 

 duty on imports of tires, namely, $42.92 per hundred- 

 weight; but Japan has quite an idea of becoming a rubber 

 manufacturing country and therefore believes in adequate 

 protection. 



THE FLYING MACHINE IN WAR. 



' I 'HE recent manceuvers of Zeppelins over Paris and 

 ■*• the threat that with the calmer airs of June they 

 will rain explosives upon London have served to increase 

 interest in these new and spectacular engines of warfare. 

 The chief military service of these ships of the air so far 

 consists of detective rather than destructive work. They 

 have not proved particularly efficacious in the wiping out 

 of battalions ; but they have proved exceptionally efficient 

 in locating the hidden enemy and in indicating his posi- 

 tion with such accuracy that the gunner back behind the 

 hills could wipe out his battalions — which is quite as 

 effective. 



In the construction and operation of this aerial craft 

 rubber plays a dominant part. Several pages are de- 

 voted in this issue to describing in detail the extent to 

 which rubber enters into the building of aeroplanes and 

 dirigibles and the manner in which it enables the pilot to 

 keep his working energies in the rarefied atmosphere of 

 great altitudes and even for a considerable length of 

 time under the surface of the sea, in case he falls and is 

 submerged. Aviation in warfare will undoubtedly de- 

 velop immeasurably beyond its present condition, but it 

 is doubtful if it will ever develop beyond its dependence 

 on rubber.
