THE COLORADO RUBBER RECORD. 



IN view of the continued receipt of inquiries concerning the 

 production of rubber from the Colorado " rabbit weed," 

 a further record is presented herewith of what it has been pos- 

 sible to learn in regard to the development of the new industry. 

 It does not appear that the Colorado product has yet found a 

 place in the crude rubber market.

Salida, Colo., Feb. 19. — The final deal was consum- 

 mated this morning between the Salida Board of Trade 

 and Dr. Sol Kingolskv, proprietor of the rubber extraction 

 plant, now at the Modern Machine Works in Denver, 

 whereby the machine will be set up at Salida for the man- 

 ufacture of crude rubber. The plant will be shipped to 

 Salida within the next few days and set up in the Creamery 

 building, which is well equipped with machinery.

LFrom Ihe Denver (Colorado) Republican^ December 15, 1904. J 

 Salida, Colo., Dec. 15. — (Special.) — The work of set- 

 ting up a rubber extraction plant in Salida was begun this 

 morning by the Salida Crude Rubber Co. The machinery 

 arrived last night, and the new mill will be operated within 

 15 days. - - - The Salida company has placed a num- 

 ber of workmen in the field who are gathering the root for 

 the new mill. 



[Fiom the Salida (Colorado) Chronicle, December 16,1904.] 

 As announced last week, the building for the Salida 

 Rubber Plant has been made ready. A portion of the ma- 

 chinery has arrived, is installed, the fires in the furnaces 

 kindled and the wheels set to flying. The remainder oj 

 the machinery is being manufactured as rapidly as possible. 

 Contracts have been placed for the gathering of the rub- 

 ber weed - - - This is the first and only rubber plant in 

 the world in operation to manufacture rubber from the 

 Colorado weed - - - The untiring efforts of the Salida 

 Board of Trade to promote the possibilities of Salida are 

 bringing results. 



[From the Salida (Colorado) Mail, January 31, 1905.] 

 Every new discovery of whatever nature is forced to 

 pass through the fiery furnace of adverse criticism. It 

 has to rise on its merits. So it is and has been with the 

 Colorado rubber weed. Since its discovery it has been 

 met with suspicion and has gradually emerged from ob- 

 scurity into great prominence. Every month brings to 

 light some new value connected with its usefulness.

The Insoi.oidFuse Co., Ltd. — Gentlemen : Your caid 

 requesting sample of "Crude Rubber" at hand. The 

 mill for extracting the same has not started up yet and 

 consequently we have none on hand. 



The manager says he cannot do much until the ground 

 thaws out so they can pull the plant. 



Later on we will be glad to forward rubber. Very re- 

 spectfully, O. J. Kennedy, Sec. B. of T.

Dear Sir : Really I do not know why the rubber pro- 

 ducers of Colorado do not allow you to see samples of 

 their product. But I do know that I had not the slightest 

 difficulty whatsoever, not only in obtaining all the samples

[From the Salida (Colorado) Mail, January 31, 2905.] 

 Mr. O. J. Kennedy, secretary of the Salida Board of 

 Trade, has received a communication, dated January 18, 

 from Buffalo, New York, people who wish their names 

 withheld, from which the following extract is taken : 



" I am interested in a process for abstracting rubber 

 and Gutta-percha from many different plants, vines, 

 grasses, woods, etc. We have been at work on the pro- 

 cess for several years and can produce hard rubber from 

 many substances in paying quantities. We have lately 

 tested the Colorado rubber plant and pronounce it the best 

 material for hard rubber — that is, it will produce it far 

 cheaper than from any other substance of equal sort. We 

 can obtain from this rubber plant a higher percentage 

 than we have ever heard of." 



[From the Brooklyn (New York) Daily Eagle, December 18, 1904.] 

 Myron G. Brownell, a Denver real estate man, visited 

 a friend engaged in the sheep business near Buena Vista. 

 The friend had a valuable ram* that had carelessly been 

 permitted to browse on rabbit weed, and a couple of weeks 

 later died with the usual symptoms. At Mr. Brownell's 

 suggestion a post mortem was held on the ram. The 

 stomach was found to be filled with pellets of a black gum. 

 This gum was perfectly indigestible, and so had caused 

 death. Mr. Brownell had some of the substance examined 

 by a Denver chemist, who said it was rubber. 



* For a portrait of the ram, see The India Rubf.er World, Jan- 

 uary 1, 1905 (page 126). 



[From the Salida (Colorado) Mail. January 10, 1905.] 

 According to sworn affidavits of witnesses Brownell 

 never dreamed of such a thing as a rubber plant, until 

 Spencer, under promise from Brownell to give him a large 

 bunch of money if he, Spencer, could show him the plant. 

 He took him into the field and pointed it out to him. 



THE CARE OF RUBBER TIRES. 



IN view of the great number of automobiles stored during the 

 winter months, the G & J Tire Co. (Indianapolis, Indiana) 

 have issued " A Word of Advice " in regard to the care of tires 

 when not in use, which we take the liberty of reproducing: 



Extreme cold will not damage tires in any way, but great variation 

 from heat to cold is injurious to tires which are not in use. Therefore, 

 if a car is stored in a room that is artificially heated, the temperature 

 should be kept as even as possible. 



If the car is stored in alight place, it will be well to cover the tires to 

 protect them from the strong light, which has a deteriorating effect on 

 rubber. 



The greatest injury that can be done to tires on a car stored for the 

 winter, is to allow the weight of the car to rest on the tires. The car 

 should be blocked up, so that no weight is borne by the tires, and the 

 tires should then be deflated partially. This will relieve the tires of all 

 strain, so that in the spring they should be no worse for their winter's 

 storage. 



F. B. Parks, of No. 173 Prescott street, Grand Rapids, 

 Michigan, the patentee of an inner tube for tires which is de- 

 signed to be non puncturable, or at least self healing to a de- 

 gree hitherto unknown, has contracted for its manufacture by 

 the Alden Rubber Co. (Barberton, Ohio). Before making this 

 arrangement Mr. Parks, who is the patentee of several other 

 rubber specialties, had attempted to organize a company in 

 Grand Rapids to make his tire.
