"7-LEAGUE" RUBBER BOOTS. 



IN the ci Ity hi rubber footwear, with 



1 sewed leather soles, the vamp lining of the I t, as well 



as the counter lining, instead of being turned in under the foot, 

 as is done ordinarily in making rubber boots, is turned out over 

 the welt. A v. I two layers of canvas with rubber 



between them is then pi I on thi il of the boot, and on 



the outside of the boot a strip of canvas extending about an 

 inch above the sole is placed all the way around the loot. This 

 also extends out over the out turned upper, and is forced into 



Mil by a blind stitcher. The shell is thus vulcanized, 

 which it is stitched with a stitching machine, the stitchi

vamp and counter lining the welp sole and the wearing sole. 

 In this maimer the threads pass through four thicknesses of 

 canvas, making a juncture so strong that no nails are necessary 

 in the sole of the boot to hold it fast to the upper. Of course, 

 nails are placed in the heels to hold fast the lifts and top 

 piece. The illustration is intended to give the idea of a mag- 

 nifying glass showing details of construction. These hoots 

 are patented — United States No. 895,284 — and other designs 

 and patents are being applied for. The name of the hoot is 

 protected by copyright. The rubber part of these boots is 

 made by one of the principal rubber shoe factories. They are 

 placed on the market by the owners of the patents. Mulconroy

THE MERIT OF RUBBER MATS. 



A N important rubber firm specializing in the line of goods 

 •** referred to states: "No other form of floor covering so 

 thoroughly and satisfactorily fills the bill as rubber mats and 

 matting. They are sanitary r , noiseless, odorless, durable, eco 

 nonical and attractive, thereby filling every requirement of a 

 modern floor covering. No other material combines these neces- 

 sary and desirable features. - - - These goods arc especially- 

 adapted for use in public and private buildings, institutions of 

 all kinds, libraries, schools, churches, office buildings, banks, rail- 

 road stations, elevators, carriages, automobiles, boats, and in fact 

 wherever a serviceable, sanitary and economical covering is 

 desired." 



The same company advise their patrons: 



"When ordering lettered mats, do not use too much wording. 

 A mat filled with letters is not effective. Letters smaller than 

 3 inches long do not show to advantage. In order to calculate 

 how many letters you can place 011 a line, bear in mind that a 

 letter occupies a running space about equal to its height, and 

 that s inches on each side and at either end is taken up by the 

 border of the mat. - - - We are frequently asked how long 

 and how wide we can make perforated mats. We can make them 



THE AMAZON RUBBER SYSTEM. 



[FROM rHE "BULLETIN OF Mil-: AMERICAN REPUBLICS."] 



AX intelligi nl survej of " I he Rubber System of the Ami 

 as published in The India Rubber World for July 1, 1900 

 [page 347], 1- made by Gusta\ Heinsohn. Primarily designed 

 as a clear statement of the writer's views in regard to the so- 

 railed rubber valorization project, many instructive facts as to the 

 gathering and marketing of this valuable commodity are furni 

 It also corrects a mistake too prevalent abroad that "Amazon 

 rubber is obtained by haphazard methods by ignorant denizens 

 of the fori Si " To support the contention it is asked: "If it were 

 not for a well organized system how could Para show a certain 

 and well sustained and annually growing export of rubber?" 



FOUNTAIN SYRINGE IMPROVEMENT. 



PATENTS have recent l\ been granted for an improved foun- 

 tain syringe bag, which will be appreciated by users, and 

 no doubt interest rubber sundries manufacturers. In recent 

 years there has been an increased demand for bags with larger 

 openings or inlets, in order to permit of cleansing the inside, 

 also to facilitate easy filling from a pitcher or other ves- 

 sel. For hospital or general use, physicians advise bags 

 with large inlets. Most bags made heretofore, whether with 

 small or large openings, have been limp at the top, making it 

 necessary^ to hold them open when being filled. If made with 

 a wide inlet the sides hang down, often spilling a portion of

 the content-. The Pearl patents cover distending rings hinged 

 to the inside of the bag, opening the ring readily folding 

 down into the hag when the syringe is boxed, as indicated by 

 the dotted hues in Fig. I. When in use the ring is drawn u> 

 firmly into the bag neck, forming a rigid edge, as shown in 

 Fig. 2. Distending rings are also made in various sizes so 

 formed that they may be sprung into the bag inlet and firmly 

 held without being hinged. These rings are made of nickel 

 plated wire, celluloid, hard rubber and aluminum, also wire 

 covered with rubber tubing, depending on the quality of bags 

 fitted. These hag distending rings are the invention of Eugene 

 Pearl, No. _>.l Union square. New York. 



The president of Brazil, on August 5, signed decree No. 

 7485, authorizing the operation in that republic of Deutsch- 

 Siidamerikanische Telegraphcn-Gesellschaft. A.-G., formed in 

 Germany with 4,000,000 marks [=$952,000] capital, to lay a 

 cable from Borkum to TenerifTc, and thence to Brazil.
