SOME FORGOTTEN TONS OF FINE PARA. 



' I 'H.-\T JJi-azil, notably Para aiul Amazonas, is pro- 

 •*■ foundly stirred over the gfeat areas of cultivated 

 Hevca that the tropical world possesses, is a mild 

 way of stating a very patent fact. Yet it is probable that 

 neither of the great rubber states mentioned, reahze how 

 strong is the position of the outside crude rubber in- 

 terest. Nor do they perceive that Upriver fine is not the 

 necessity that it was but a few short years ago. So great 

 has been the progress in the art of preparing and learn- 

 ing to use rubber once deemed inferior, that most of 

 the rubber manufacturers could, if they would, produce 

 high-grade goods without using a pound of Brazilian- 

 grown rubber. In other words, with other grades in the 

 market, while they might prefer Para, they can get 

 along without it. Plantation rubber, shrub rubber, such 

 as guayule, extracted rubber, pseudo rubbers, arc real 

 Para substitutes in hundreds of rubber mills, and manu- 

 factured rubber goods grade as high as ever thev did. 

 There is, however, another source of supply that crude 

 rubber men are likely to overlook, yet one that will won- 

 derfully help in case of a short crop or too high a range 

 of prices on the Amazon. The world, not the tropical 

 world, but the teinperate zone, possesses several million 

 pounds of Para rubber that will be shortly oiifered to 

 the trade at from 50 to 70 cents a pound. There will be 

 a steady offering of it for years to come and the supply 

 will increase. Its source is the worn-out motor tire that 

 goes to the reclaimer and is thoroughly "recovered." 

 For five years past the tire manufacturers have been 

 turning out tons of tires and paying a high price for raw 

 material. This great accumulation of iTibber is just 

 beginiiiiig to come back, and is of a grade that can be 

 used in almost any line of work. Those who valorize 

 must reckon with this great invisible supply as well as 

 with the visible. 



RUBBER MANUFACTURERS AS PLANTERS. 



' I 'HE news that one of the great rubber companies is to 

 *■ plant Hevea on a very large scale is of special inter- 

 est not alone to its stockholders, but to the trade at 

 large. The wisdom of such a move is unquestioned. The 

 experimental stages of Hevea planting have passed. It
