RUBBER RESULTS IN MEXICO. 



In a report to the stockholders in the Mexican Mutual 

 Planters Co. (Chicago), owners of "La Junta" plantation, in 

 Mexico, the president, George C. Sanborn, under date of April 

 27, 1908, writes that during January and February last some 

 experimental tapping was done on 6'^ year old Castilloa rubber 

 trees, to test certain points, and that 1400 pounds of dry rubber 

 were obtained, at a cost of about 25 cents per pound. Mr. James 

 C. Harvey, the plantation manager, on his neighboring private 

 plantation, it is stated, tapped some /!/< year old trees, gaining 

 1000 pounds of rubber, at a cost of 23 cents a pound. The ex- 

 periments are considered as having resulted favorably, but com- 

 mercial tapping is not planned be- 

 fore the trees are 8 years old. 

 As the trees advance in age and 

 increase in productiveness, Mr. 

 Sanlxjrn thinks that the cost of 

 gathering rubber will drop at least 

 to 12 or 15 cents a pound. 



The IQ08 report on the planta- 

 tion of the Ohio Rubber Culture 

 Co., near Manatitlan, Mexico, was 

 written by Charles S. Eddy, of 

 Akron, Ohio, chosen by the share- 

 holders to visit the property. 

 Their plantation is not yet old 

 enough to yield rubber, hut Mr. 

 Eddy wrote that he visited two 

 private plantations near Tuxtepcc, 

 which arc yielding satisfactorily. 

 These are not named in the report 

 but Mr. Eddy informs The Iniha 

 Rubber World that one property 

 is the sugar and coffee plantation 

 of Sefior Don Joaquin Jiminez.

for coffee shade. The other property, three miles from Tierra 

 Blanca, Mr. Eddy mentions in his printed report as having 7 and 

 8 year old rubber trees, which were being tapped lightly but 

 yielding at a rate which netted $1200 a month. This property 

 is owned by F. A. Hardy (president of The Diamond Rubber 

 Co.), R. Cluke, and R. S. Willis, of Chicago, the latter being 

 manager. Mr. Eddy states that he understands the $I2C0 to 

 mean gold. 



On the property of The Tolosa Rubber Co., in Oaxaca, Mex- 

 ico, Mr. W. L. Wadleigh in February tapped 50 Castilloa trees, 

 5 years and 8 months from planting, and averaging 18.7 inches 

 in girth. The yield from the one tapping was 71 ounces of 

 rubber, or nearly 1J/2 ounce per tree. Five diagonal cuts were 

 made in each tree and the latex coagulated in the cuts.
