case is made of drill and is held in place by five buttons. It 

 is waterproof and is referred to as being very serviceable. 

 It retails at $2. [Hopewell Brothers, Cambridge, Massa-

"PEERLESS EMPIRE" MOTORCYCI.E V BELT. 



The manufacturers of the belt illustrated herewith pomt 

 to the fact that it is the first one of American make to be 

 offered to the trade, while they guarantee it to be as good 

 as anything imported. The illustration shows it in the form 

 in wliich it is packed for shipping. [Empire Automobile Tire 

 Co., Trenton, New Jersey.] 



COATING FABRIC WITH POWDERED WASTE. 



■ I 'HOMAS GARE, a well-known British experimenter, has 



*■ patented a short cut in the manufacture of rubber plastics. 



For example, he takes powdered rubber waste, sprinkles it on 



a fabric which, running over suitable rolls, enters a revolving 



Thom.\s G.\re's Rubber Machine. 



drum where a rotary surface presses the waste to the desired 

 density, frees it from air, devulcanizes and revulcanizes it. so 

 that it emerges a calendered, vulcanized, finished sheet, with a 

 fabric backing. 



COAGULATING LATEX BY ELECTRICITY. 



QUITE a novel invention is that shown in the accompanying 

 illustration, which is in brief an endless belt, the upper 

 surface of which is coated with graphite, so that when it is 

 electrified it becomes a continuously moving anode. The 

 cathode made of suitable metal hangs aljout one-half inch above 

 the surface of the belt. The latex held in the tank shown in 



Cockerill's Electrical Apparatus for Coagulating L.a 



the picture is allowed to run down upon the slowly moving belt 

 where the current of electricity coagulates it, the water run- 

 ning off into drip pans below. The film of rubber is scraped 

 from the surface of the traveling anode and run through 

 squeezing rolls which expel any surplus moisture. This has 

 been patented by Thomas Cockerill, of Ceylon. 



INTERNATIONAL RUBBER EXHIBITION. 



It is stated that the German rubber manufacturers have prom- 

 ised to support the International and .-MHed Trades Exhibi- 

 tion, which is being organized for London for May, igri, and the 

 Standige Austellungskommission fur die Deutsche Industrie, a 

 semi-government affair, have also given their support. 



RUBBER PRODUCTION OF PERU. 



THE steady increase m the export of rubber from Peru is 

 indicated by some figures kindly supplied to The India 

 Rubber World by Senor Don Eduardo Higginson, thi 

 Peruvian consul-general at New York, for 4 recent years, during 

 which time the total from Iquitos increased 33 per cent. 



As for the grades covered by the following table, compiled by 

 the consul-general, it may be noted that "slabs" and "sausage and 

 balls" are different grades of the rubber known in the United 

 States trade as Caucho and hitherto in some other markets as 

 "Peruvian rubber." In recent years, however, the collection has 

 increased in Peru of rubber of the same grades as Para, which 

 rubber formerly was described often as "Jebe" {Hcvea). In the 

 table, therefore, the terms "fine" and "coarse" are Para rubber, or 

 "Peruvian fine" and "Peruvian coarse," the term Peruvian here 

 having now a different designation than formerly. "Weak rub- 

 ber" is believed to come from a Hevea species in the Peruvian 

 uplands, as distinguished from the trees growing in districts sub- 

 ject to annual overflow of the rivers. 



In the table annexed "Pacific ports" include Callao and Mol- 

 lendo. Values are stated in United States gold. The table fails 

 to include the shipments through Pacific ports in 1904 and 1903:

INAMBARI rubber RESULTS. 



At the first annual meeting of The Inambari 

 Estates Limited (London, January 28), the chairman. Sir 

 William Martin Conway, went into detail as to the extent to 

 which preparatory work on the company's properties in Peru 

 had absorbed the energies of the management during their first 

 year, ended June 30 last. They had practically completed the 

 building of the roads required by the government as the price 

 of their concession, and would be in a position shortly to place 

 on the river Inambari the small steamers needed in carrying 

 out the business proposed. The collection of rubber during the 

 first year amounted only to 12,307 pounds, which was sold at a 

 good price. But there were now 200 rubber pickers on the 

 ground and others had been contracted for; the company had 

 stocks of merchandise for use in trading with the natives, and 

 they felt in a position now to carry on extensive operations in 

 rubber gathering in the current year. The rubber referred to is 

 Hevea, besides which caucho has been discovered on the estate, 

 and they have also bought some caucho from neighboring prop- 

 erties which are not so well provided with outlets to market.
