'X'HE authors of this work bring to its production the aid 

 * of a familiarity with the chemistry of rubber and with 

 factory practice, and while they by no means undertake to 

 set down all that is needed to make the rubber manufacture 

 a success, they do point out clearly the task which confronts 

 him who would master the essentials in this much diversified 

 industry. Thus there is enough in regard to the nature of 

 rubber and the difference between the various commercial 

 grades, to help one appreciate the importance of care in the 

 proper selection for compounding for different kinds of goods. 

 The importance of proper compounds is nowhere lost sight 

 of, and nearly a hundred typical mi.xtures are given in the 

 book. Of course a book of compounds alone will not make 

 a rubber factory superintendent any more than a "cook book" 

 will make a chef; still, before making up rubber goods one 

 must know what to put into them, and an idea of what pro- 

 portions have proved successful in practice is helpful. 



Illustrations are given of the principal machines used in 

 rubber working, with an account of the function of each and 

 instruction in its use. There are details on the manufacture 

 of twenty classes of soft rubber goods, from hose pipes to 

 elastic threads, and also on hard rubber goods, following 

 chapters of a general nature on washing, mi.xing, calender- 

 ing, and vulcanizing. There is also a chapter on reclaiming 

 rubber. Incidentally the history of the rubber industry is 

 told briefly, ascribing the discovery of vulcanization to Good- 

 year. The authors have a field large enough for an encyclo- 

 pedia, but in their restricted space the ground has been 

 covered well. 



RUBBER CULT1V.'\TI0N IN THE BRITISH E.MPIRE. A LECTURE 

 Delivered before the Society of .Arts. By Herbert Wright, a. r. c. s., 

 F. L. s. London: Maclarcn & Sons. 1907. ICloeii. i6inc. Pp. vn-|- 

 100-f.plates. Price, 2S. 6rf.] 



The author, until lately controller of the Ceylon govern- 

 ment experiment station, where he devoted much attention 

 to rubber culture, on being invited to address the Lon- 

 don Society of Arts, sketched the extent and limitation of 

 the natural sources of rubber, and the development of plant- 

 ing the different species in various regions, but particularly 

 within the British empire. Results are stated in detail, with 

 a forecast based upon what has been accomplished to date. 

 The publishers, by special arrangement, have brought out the 

 present edition of the lecture, in addition to its publication by 

 the society, adding illustrations and notes of interest. The 

 lecture is followed by a report of the discussion to which it 

 gave rise, and in which several rubber brokers and manu- 

 facturers participated, the whole indicating how deeply the 

 rubber trade in Britain are becoming interested in the plant- 

 ing question, 



THE CONGO. A REPORT OF THE COMMISSION OF ENQUIRY 

 Appointed by the Congo Free State Government. A Complete and 

 Accurate Translation. New 1 ork and London: G. P. Putnam's Sons. 

 1006. [Cloth. Svo. Pp. i-i. Price, $1.] 



While this is not, strictly speaking, a book about rubber. 

 the rubber trade lies at the bottom of the Congo question, 

 which question probably will not be settled with much 

 definiteness until the wild supplies of rubber have become 

 exhausted. What may then be developed in the way of 

 mineral wealth is another question; also whether Leopold's 

 heirs in the ownership of the Congo will administer it better 

 than he has done. As to the excellence of the translation, 

 as claimed on the title page, we can say nothing. The book 

 is informing in regard to the Congo country in general, and 

 no doubt is more trustworthy than the books of the "horror" 

 writers who have had so much to say about that part of cen- 

 tral Africa. 



SELF PROPELLED \ EIIU LES. A PRACTICAL TREATISE ON THE 

 Theory, C'onstruction, Ojicration, Care and Manaf{cmenl of all Forms 

 of .-\ulomohilcs. By .lames E. Homans, a. m. New York: Thco.

This is the sixth edition of a practical book intended to 

 help machinists and owners of motor cars to understand the 

 construction, use and care of these vehicles. The work has 

 "worn" well and with each new edition it has been brought 

 more up to date and rendered broader in scope. Four of 

 the 51 chapters are devoted to tires, besides which these 

 necessary appendages of the automobile arc referred to fre- 

 quently elsewhere in the book. 



I50LI\ lA. ADDRESS DELUERED BY THE BOLIVIAN MINISTER, 

 Mr. Ignacio Caldcron. Under the. .Auspices of the National Geograph- 

 ical Society, at Washington, D. C. Second Edition. London: 1907. 

 [Paper, 8vb. Pp. 21.] 



While the natural wealth of Bolivia to-day is no greater 

 than before Columbus turned traveler, it is much nearer 

 realization, and a valuable service is being rendered to the 

 country by its capable representative at Washington, the 

 author of this address. Bolivia's greatest handicap is the 

 lack of transportation facilities, being denied access by water 

 to the seaboard, but the railway construction now assured 

 will before many years open the way to rubber fields reputed 

 to l)e the richest in the world.

The preferential tariff concessions of Brazil in favor of cer- 

 tain products of the United States, in effect temporarily for some 

 time past, have been made permanent. Under these provisions 

 manufacture of india-rubber, gutta-percha and celluloid are ad- 

 mitted at rates of duty 20 per cent, lower than are applicable 

 to products of other countries.
