A Text Book of Rubber Manufacture. 



By HENRY C. PEARSON. 



It is often a great convenience to bave .it hand, 

 in convenient form t'>r refer* nc< . a book that will 

 remind a man of something which he needs t" 

 make use of in his work or business, without wait- 

 ingto ransack his memory for it no mattei how 

 well he may once have learned it. "CrudeRub- 

 ber and Compounding Ingredients" lias been de 

 signed to serve just such a purpose. Intact the 

 book was a gradual development of a manuscript 

 reference book originally compiled by the author 

 for his personal use alone. Finding bow conven- 

 ient it was to be able to turn to such a book, instead 

 of having to depend on memory alone for the in- 

 formation it contained, the idea suggested itself 

 that possibly others interested in the rubber indus- 

 try might find these notes equally serviceable, .and 

 this is why they have been developed into a book. 

 The reception of the book has been encouraging, 

 and it may interest some who do not yet possess a 

 copy of the book to know how some practical rub- 

 ber workers regard it. 



A. superintendent writes: "It is a work that I 

 want on my desk all the time, as it is surprising 

 how often one wants to refer to it." 



The manager of an important concern writes 

 of the book : "Its value has grown on me ; I now 

 keep it by me in the factory and use it constantly, 

 both for reference and suggestion."
