AS indicated liy its title. ".Manual for the Preparation of 

 Rubber," this work is intended to serve as a handbook for 

 the use of planters in preparing their rubber for market. It 

 is especially intended for planters in the Dutch colonies but 

 can be used to advantage by all rubber planters acquainted 

 with the language of the Netherlands. .\ clear idea of its 

 scope can be formed from the following titles of its several 

 chapters: 



Latex in the Gardens and in the Factory; Determination 

 of the Rubber Content of Latex; Preparation of Rubber 

 Sheet; Mistakes Made in Preparing Rubber Sheet; Prepara- 

 tion of Rubber Crepe; Mistakes Made in Preparing Rubber 

 Crepe; Preparation of Inferior Sorts (of rubber); Mistakes 

 Made in Preparing Inferior Sorts; The Sorting and Packing 

 of Rubber; Prescriptions for Making Solutions Used in the 

 Preparation of Rubber. 



NEW TRADE PUBLICATIONS. 



THE Miner Rubber Co., Limited. Granby, Quebec. Canada, 

 has issued its catalog No. 7 for 1916-17. It is a hand- 

 somely illustrated 64-page book showing the many styles of 

 rubber footwear made by this company. A decided innova- 

 tion in printing pictures of rubber footwear is the showing 

 of the rubber overshoe in full black, while the exposed por- 

 tion of the shoe is printed in a soft gray half-tone effect, 

 making a striking illustration. Beside the regular line of 

 rubber boots and shoes several specialties are shown, one 

 being a rubber boot of heavy gum with leather sole quilted 

 with hob-nails. There are also boots with red soles and 

 boots entirely of red gum. A list of the new pressure-cured 

 goods in gray finish is illustrated, and also a large list of 

 outing shoes in white, gray, tan and blue canvas with self- 

 colored or contrasting rubber soles. The book contains other 

 information of interest to dealers in this brand of rubber 

 footwear. 



Link-belt machinery is fully described and pictured in a 

 finely printed book published by the Link-Belt Co., Chicago, 

 Illinois, in which are shown many fine half-tones of the 

 lines of conveyors and elevators made by this company. Of 

 special interest to the trade are the conveyor belts oflfered 

 by this concern, which are rubber belts from three to ten 

 ply. with an extra rubber cushion on the carrying side l/16th 

 to 14 of an inch in thickness. This cover or cushion is turned 

 around the edges and vulcanized on the under side, and thus 

 is less liable to crack or peel off than might be the case with 

 belts where the rubber edges are molded on separately. 

 There is much information of a general character for con- 

 cerns handling coal, stone, gravel, sand or similar products. 



W. G; Brown & Co., Cincinnati, Ohio, dealers in crude rubber, 

 distribute monthly a picturesque little calendar, the one for March 

 bearing a striking lithograph of two midnight visitors with bur- 

 glarious intent arousing a sleeping couple. While, perhaps, the 

 picture is not particularly appropriate to the business of the 

 firm, the calendar is an attractive and convenient desk ornament. 



Decreasing truck vibration is treated in a booklet issued 

 by The B, F. Goodrich Co., .-Xkron, Oliio, explaining the 

 "l)c Luxe" ami regular solid truck tires made liy that com- 

 pany. Illustrations and diagrams, together witli suitable 



text, are intended to prove that these tires decrease truck 

 vibration and tend to give more comfortable as well as much 

 longer and more durable service than ordinary tires. The 

 booklet, though a small one, is gotten out in very attractive 

 form and reflects great credit on the advertising department 

 of the Goodrich company. 



The Kokomo Rubber Co., Kokomo, Indiana, is sending 

 out to the trade a rather striking folder which shows a 

 half-tone reproduction of the first automobile built in America 

 and which was equipped with the first automobile tires made 

 in .\merica or in any other country. The folder is devoted 

 to advertising the Kokomo Gridiron Non-Skid and the 

 Kokomo Smooth Tread tires, both of which are pictured and 

 explained. In a corner of the folder is a form which 

 can be detached, then becoming a post-card directed to the 

 company, which needs only the signature and address of 

 the sender to receive further information regarding these 

 tires. 



A very attractive piece of advertising comes from tlie Cana- 

 dian Consolidated Rubber Co., Limited. Montreal, Canada, it 

 being a folder bearing the question : "Who Wears Rubber Foot- 

 wear?" and answering that question by showing about 30 pictures 

 of people in various walks and rides of life wearing rubbers. The 

 vacuuin process of vulcanizing is explained with a cut showing 

 a hand holding a piece of the pressure cure soling and another 

 piece vulcanized by the old method, thus contrasting strongly 

 the difiference between the two. The folder is as attractive in 

 its text as it is in its illustrations, and is one which will be 

 given more attention than the average piece of circular mail 

 matter. 



Another folder gotten out by this company that is worthy of 

 special mention is one showing a rolled edge lumberman's over, 

 and one with a plain edge sole, but of red rubber. A fine look- 

 ing young man is represented as showing the differences between 

 these two, being photographed in various positions, the accom- 

 panying argutnent being that as each has the same amount of 

 rubber in the sole, the plain edge sole necessarily has more wear 

 where the wear comes than if a portion of the material was 

 surrounding the upper. Some argument regarding the vacuutn 

 vulcanization is also given. The circular is attractively dis- 

 played in three colors of ink, and is a worthy companion of the 

 previously mentioned one. 



The Raw Products Co., New York City, is sending out to 

 its customers a very comprehensive sheet giving the india 

 rubber statistics for the year ending December 31, 1915, 

 which shows the United States imports and stocks on hand 

 of the various kinds each month in the year, the same facts 

 regarding England, and the monthly quotations, the arrivals 

 at Para, stocks at Para and Manaos and the plantation pro- 

 duction. There is also a diagram showing the fluctuations 

 of fine and coarse Para and of First latex crepe for 1913, 1914 

 and 1915. It will make a very convenient and comprehensive 

 document for ready reference. 



Owing to the seizure by the British Government of many 

 of the motor vehicles for war purposes, there has lieen a re- 

 markable increase in the importation of .'American trucks and 

 other commercial vehicles. As the tires for these are measured 

 in inches, while tires made upon the continent or in Great 

 Britain are almost invariably given in metrical measurements, 

 The B. F. Goodrich Co., Limited, London, England, has issued 

 a booklet entitled "Goodrich Solid Rubber Band Tyres. Inch 

 Sizes for .American Vehicles." Besides a general description, 

 with half-tone illustrations and diagrams, it gives in tabulated 

 form the size in inches, the diameter over permanent steel 

 band, maximum load for tire, price, and code word for facili-
