Crude Rubber .^nd Compoundi.ng Ingredi- 

 ents. A Text-Book of Rubber Manu- 

 facture. By Henry C. Pearson, Editor 

 of The Indi.\ Rubber World. Second 

 Edition. New York : The India Rubber 

 Publishing Company, 1909. 

 This is the second edition of a book which 

 appeared ten years ago, and which may be re- 

 garded as a standard work on the subject in 

 English. Since the appearance of the first edi- 

 tion the rubber industry has made rapid 

 strides. New sources of rubber have been 

 opened up and progress has been made in re- 

 claiming waste rubber. In this revised edi- 

 tion the improvements in the art have all been 

 conscientiously noted. The many new com- 

 Ipounding ingredients, substitutes and processes 

 find a place in its pages. As it stands the 

 book is a dictionary of compounding facts, 

 and an encyclopedia of rubber factory prac- 

 tice, intended primarily for factory use. 



From A LEADING RUBBER MANUEACTURER 



Your "Crude Rubber ami Manufacturing In- 

 gredients" certainly contains a fund of val- 

 uable information, and is used daily in our 

 laboratory as a text-book. To our mind no 

 manufacturer of rubber goods can afford to 

 be without it.

Mr. Henry C. Pearson's text-book on rub- 

 ber manufacture, entitled "Crude Rubber and 

 Compounding Ingredients," has now gone into 

 its second edition. A copy of this production 

 is before us and we anticipate a very large 

 demand, for the compilation has been made 

 more attractive than ever and has been 

 brriught up to date in every chapter. The first 

 edition appeared ten years ago, and since that 

 time many changes have been chronicled, es- 

 |)ccially the making of motor tires, which Mr. 

 Pearson describes as a new development, oc- 

 cupying to-day one of the great divisions 

 in the manufacture of rubber goods. New 

 compounding ingredients and substitutes have 

 naturally increased in number in the interval 

 between the two editions, and in the present 

 issue only those of a real or suggestive value 

 have been utilized. As the author claims, it 

 still remains a dictionary of compounding 

 facts; an encyclopedia of rubber factory prac- 

 tice. .'\ttention is drawn to the fact that for 

 some years past the price of crude rubber has 

 been high, and has consequently led manufac- 

 turers to inquire into the value of materials, 

 such as Pontianak. Gums of this character 

 are described in the volume before us. - - - 

 There is an additional chapter in the second 

 edition, making a total number of fifteen, 

 which refers entirely to reclaimed rubber and 

 its uses. In this section a brief account is 

 given to the various processes adopted at the 

 present time. We congratulate Mr. Pear- 

 son on his second edition and feel that, though 

 it was promised to us in December of 

 last year, it has been well worth waiting for.
