THE INDIA RUBBER WORLD 



145 



New York newspaper a half page report of a day's court pro- 

 ceedings in a case where a million dollar company — capital actual 

 — are claiming damages for infringement of patents on an aero- 

 plane. These things do not happen in regard to an invention 

 without practical value. 



Mr. Lougheed, our author, made an admirable record as editor 

 of the important journal. Motor, and the thoroughness of the 

 book before us indicates that he has studied the matter of mono- 

 planes and biplanes, not to mention ornithopters and helicopters — 

 and, of course, balloons — no less carefully than in the case of 

 automobiles in earlier days. The book is actually up to date. 

 There are 270 illustrations — many of them "half-tones" of ek- 

 ceptional merit — patent specifications, a glossary of aeronautical 

 terms, and other interesting features in this book too numerous 

 to recount in a journal interested in flying machines only in so 

 far as rubber is used in their construction. Incidentally- it may 

 be stated that the rubber requirements for these new machines 

 form by no means the least important item of cost. 



HANDBOOK OF BRITISH GUIANA. 1909. COMPRISING GENERAL 

 and Statistical Information Concerning the Colony. Edited and Compiled 

 by George D. Bayley lot the British Guiana Civil Service). Published 

 under the authority of the Permanent Exhibitions Committee. George- 

 town: ''The Argosy" Co., Limited. 1909. [Cloth. 8vo. Pp. xxv -f 607 

 -f plates. Price. 5 shillings.] 



The natural resources of British Guiana compare favorably 

 with those of any other English-speaking colony in the world, 

 and it is of interest to note the efforts now being made to pro- 

 mote their long delayed development. Not only are there great 

 riches in the forests, and in the as yet little worked rhines of 

 the colony, but there are large areas fitted for tillage and grazing, 

 the whole giving the colony great potential wealth. The book 

 before us has been compiled under official auspices with a view 

 to educating the colonists themselves as to the country in which 

 they live, and merchants, farmers and capitalists elsewhere as 

 to the opportunities which British Guiana offers for investments. 

 There is scarcely any character of information regarding the 

 colony likely to be called for in any quarter which is not fully 

 set forth in this handsome volume, the interest of which is 

 greatly enhanced by nearly threescore excellent photogravures.

The comprehensiveness and variety of the contents of this 

 yearly handbook of Dutch planting interests in the East Indies in- 

 dicate more thoroughly than does any other single publication the 

 vast importance of these interests. There are statistics of sugar, 

 coffee, tobacco, cacao, tea. spices, rice, quinine, kapok, cocoa- 

 nuts, indigo, tapioca and other products. Attention is given also 

 to india-rubber and gutta-percha, though the production of 

 these to date under cultivation is as yet only beginning. There 

 are tables of weights, measures, temperatures, prices, etc., of 

 mutual interest to estates managers in Sumatra and Java and 

 investors at home in the plantation enterprise. Professor 

 Berkhout. one of the compilers, was the former conservator of 

 forests in the Dutch East Indies, and Dr. Grehoff, the other, is 

 director of the Colonial Museum at Haarlem. The supplement 

 referred to (64 pages) is a list of books and periodicals relating 

 mainly to planting interests.

This is the eighteenth annual edition of a work which has 

 proved its usefulness to a very great number of business men 

 in a wide field. It embraces the names and addresses of over 

 350,000 manufacturing firms and individuals, under 35,774 busi- 

 ness classifications, the mere listing of which, in the index, 

 requires 77 four-column pages in small type. While not offered 

 as a complete directory of any branch of industry, its lists 



under each general heading are sufficiently full to make the 



work one of value for reference, to which are to be added the 



advantage of its being accurate and brought up to date. 



A MANUAL OF STEAM ENGINEERING, COMPRISING INSTRUC- 

 TIONS. Suggestions, and Illustrations for Progressive Steam Engineers 

 Concerning the Application to Modern Daily Practice of the approved 

 Theory of Steam Engineering. By YV. H. Wakeman. - - - New 

 York; New York Belting and Packing Co., Limited [1909.] [Cloth. 

 32mo. Pp. 409] 



The author of this handy book has written extensively for 

 steam engineers, and is an authority in his field. The present 

 work has been prepared at the suggestion of a leading firm of 

 rubber manufacturers, for distribution among their customers. 

 It cannot fail to be of interest, not only to engineers as a book 

 of reference, but also to those who have to do with the admin- 

 istration of industrial enterprises which make use of steam 

 power. 



DISEASES OF A GASOLINE AUTOMOBILE AND HOW TO CURE 

 Them. A practical Book for the Gasoline Automobile Owner, Opera- 

 tor, Repair Man, Intending Purchaser, and Those Wishing to Learn 

 the First Principles of an Automobile. Also for Launch Owners. 

 - - - By A. L. Dyke and G. P. Dorris. [St. Louis. A. L. Dyke 

 Automobile Supply Co. 1903.] [Cloth. 12010. Pp. 201. Price $1.] 



This is avowedly not a theoretical work, but one designed to 

 answer briefly but clearly a series of practical questions con- 

 cerning gasoline automobiles. As every such automobile calls 

 for rubber tires, and as these have "diseases" as well as the 

 other parts of a car, a chapter is devoted to the application of 

 tires, caring for them, and making repairs when they are needed 

 This section of the work appears to be of a practical character, 

 from which it may be assumed that the same is trite of the 

 remaining chapters. 



THE TENSILE PROPERTIES OF INDIA-RUBBER. BY PHILIP 

 Schidrowitz, p.h.d.. F.c.s., Member of British section International Test- 

 ing Committee. [Reprinted from The India-Rubber Journal, March 22- 

 May 31, 1909.] [Paper. 410. Pp. 15.] 



This paper is devoted to the desirability of standardizing india- 

 rubber goods, together with suggestions toward physical tests for 

 this purpose, by a physicist who has devoted much attention to 

 this subject. Illustrations are given of some testing machines 

 designed by him for this work.

GREAT JOY ON THE ACRE. 



•"THE following report of a joyful celebration in the upriver 

 •*■ rubber country comes to us in a Para newspaper. It does 

 not appear from the paper in what "city'* the event occurred : 



"Referring to the high price of rubber, our contemporary, 

 O Estado do Acre, in its edition of August 26, published the fol- 

 lowing : 'The people of this city received yesterday the grateful 

 news of the value of u$300 per kilo [=about $1.56 per pound! 

 of rubber. The joy was so great that immediately was organized 

 a parade of many citizens led by Colonels Laudelino Benigno, 

 Avelino Chaves, Childerico Fernandes, and Raymundo Custodio. 

 They marched through the principal streets of the community and 

 congratulated his Excellency, Dr. Jose Martins de Freitas, the 

 government delegate, and the other authorities, being on this 

 occasion treated with champagne, etc. The Estado do Acre 

 was represented at this meeting, which proved once more the 

 spirit of cordiality that exists between us.' "
