PUNCTNOT TIRE. 

 This tire is distinguished, in the first place, by its non 

 puncturable feature, provided by a patent secret process filler, 



as indicated by the 

 illustration. It is 

 likewise non collaps- 

 ible, since this same 

 filler provides a re- 

 silient cushion upon 

 which one can ride 

 [with comfort even 

 Ishould the tire be- 

 Icome deflated. The 

 Punctnot " has an 

 unconfined air tube, 

 with room for expan- 

 sion against the filler. 

 This is offered as an 

 improvement over 

 other types of pneu- 

 matic tire construction, in which the air tube is surrounded 

 wholly by a rigid fabric, which prevents expansion and is a 

 cause of leaks forming and explosions occurring. It is de- 

 scribed as being lighter in weight than other tires of the same 

 size. It is made in all sizes required for bicycle and automobile 

 use. It is understood that this is not a low priced tire, the ad- 

 vantages claimed for it being offered as an offset to the higher 

 charge made for it. The selling agents are the new firm, of 

 Coe, Smith & Co., No. 158 Summer street, Boston, the head of 

 which firm, Charles A. Coe, long was an important member of 

 the rubber shoe jobbing trade.

LA ZACUALPA RUBBER. 



THE work of La Zacualpa Rubber Plantation Co. (San 

 Francisco) has been referred to several times in The 

 India Rubber World, and they now afford a further oppor- 

 tunity for a mention of the progress made on their plantation 

 in the state of Oaxaca, Mexico. As before recorded, La Zacu- 

 alpa plantation, though formed only about three years ago, 

 embraces several thousand rubber trees (Caslilloa elastica) 

 planted by a former owner of the land, in 1889 and 1890, which 

 are now yielding an average of 1% pounds of rubber a year. 

 The company have favored The India Rubber World with a 



neat package comprising three paper boxes, each containing a 

 sample of this cultivated rubber. 



No. I shows the crude rubber, after coagulation, in the form 

 in which it is shipped from the plantation. 



No. 2 is a sample of the rubber, after having been washed, 

 sheeted, and dried, in a factory. 



No. 3 is a strip of rubber from the same lot, vulcanized, only 

 enough sulphur having been added to effect a proper cure — 

 in fact, pure vulcanized rubber. 



The rubber thus shown is of good quality, and the educa- 

 tional value of distributing such samples— several thousand in 

 number, we understand— must be very great, and is to be com- 

 mended as aiding to extend the interest in rubber planting. 

 La Zacualpa company also send advance sheets of a new 

 pamphlet about to be issued, in regard to their work, and the 

 object of which is to inform people not already familiar with 

 the subject in regard to the nature of India-rubber and the 

 methods by which it is produced. The booklet appears to be 

 well designed for this purpose, being both more accurate and 

 much clearer than many other rubber planting publications 

 that have come to hand. 



Another new publication by the company is a report on La 

 Zacualpa plantation by one of its shareholders — handsomely 

 illustrated — of which fuller mention will be made at a later date. 

 Some of the company's business plans are outlined in their ad- 

 vertisement, on another page of this paper. The company are 

 understood to have sold a considerable number of shares in 

 the Eastern states, including $10,000 worth in the town of 

 Fitchburg, Massachusetts. 



NEW TRADE PUBLICATIONS. 



THE W. D. Allen Manufacturing Co. (Chicago) have 

 issued their Catalogue No. 16. devoted to Leather Belting, 

 Brass Goods, Piston Packing, and Specialties in Mill Supplies — 

 all of theirown manufacture — and suitable for keeping in stock 

 together with the leading lines of mechanical goods, of which the 

 house named are also large handlers. [63"X2oX". 63 pages.] 

 ==A desirable feature of W. D. Allen's catalogues is that 

 the different issues are uniform in size, which adds to the con- 

 venience of keeping them together for reference. 



Allgemeine Elektricitats-Gesellschaft — the German 

 General Electric Co. — (Berlin) have issued under one cover a 

 series of twenty-six of their trade announcements, appearing 

 originally during the past four years, which, collectively, form a 

 very complete catalogue. No. i is devoted to copper wire; Nos 

 3, 10, and 23 to hard rubber insulation tubes ; No. 9 to " Sta- 

 bilit " — a patented hard rubber substitute ; No. 14 to telephone 

 cables ; No. 1 5 to trolley wire ; No. 16 to vulcanasbestos ; Nos. 

 18 to hard rubber accumulator cases, etc. Some of the num- 

 bers are price lists. A liberal use is made of illustrations, in- 

 cluding views of the factory, and the printing is of a high order ; 

 the size of the pages is 9/4X1 1/^ inches. -^^-The capital of this 

 company now amounts to 60,000,000 marks [$15,000,000], on 

 which a dividend of 12 per cent, was paid last year. For four 

 years previously 15 per cent, had been paid on a smaller capi- 

 talization. The reserve fund has reached the legal maximum 

 of 30,000,000 marks, or one-half the share capital, so that the 

 allotment of a portion of the yearly earnings for reserve will not 

 be longer necessary, and a larger share may be available for divi- 

 dends.
