Crude Rubber and 

 Compounding Ingredients. 



A Text Book of Rubber Manufacture. 



By HENRY C. PEARSON. 



It is often a greal convenience to have al hand, 

 in convenient form fi n nee, a book that will 

 remind a man of something which he needs to 

 make use of in his work 01 business, without vvait- 

 ing to ransack his memory for il no matter how 

 well he may once have learned it. "Crude Rub- 

 I Compounding Ingredients" has been de- 

 signed to serve just such a purpose. !n fact the 

 hunk was a gradual development of a manuscript 



reference I inallj compiled by the author 



for his personal use alone. Finding how conven- 

 ient il was to be able to turn tosucb a bunk, 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 mi.uht find these notes equally serviceable, and 

 ilns is why they have been developed into a boi >k 

 The reception oi the book has been encouraging, 

 and it may interest some who do not yet possi 

 copy "I the book In 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."

TO individual purchasers or plantation companies I will sell at 

 rock bottom prices Rubber and Tropical Plantation lands in 

 the states of Vera Cruz, Oaxaca, Tabasco, and Chiapas, in tracts 

 to suit, from 1,000 to 1,000,000 acres. All statements as to title and 

 value guaranteed. 



I have 1,000 000 acres of heavily timbered rubber lands that I can 

 subdivide if desired, in the heart of the Rubber, Mahogany, Cedar, 

 and Tropical Woods country on the largest river in Mexico, with a 

 magnificent saw milling and manufacturing site. It is proposed to 

 cut off the timber, — taking care of the Rubber trees now growing and 

 planting new ones, that will in a few years make a magnificent rubber 

 forest at practically no cost. Address —
