occurs on a plantation the size of mine. I cannot afford to erect a large 

 factory to handle what there is here but there should be enough stuff here 

 to make 500 pounds of pulp a day, and that is what I want. * * * 

 Very sincerely, 



Philadelphia, May 9, 1916. 

 Many thanks for the lately received copy of your highly interesting and 

 valuable Thirteenth Annual Report, which I have perused vnth lively at- 

 tention and much pleasure and profit. The amount of routine work your 

 Bureau has accomplished is amazing, without altogether neglecting more 

 attractive research work. * * * 



Heartily ^vishing you continued success in your enterprises, I am always, 

 Very truly yours, 



Manila, P. I., 19th April 1916. 

 We beg to acknowledge the receipt of your communication of the 12th 

 inst. and are very much obliged to you for the valuable information it 

 contains concerning tanning barks. 



We trust we shall soon have an opportunity t© reciprocate, and remain. 

 Yours very truly, 



Manila, P. I., April 18, 1916. 



Some months ago you were kind enough to send us your formula for 

 rendering cloth bindings vermin-proof. This formula was sent on to our 

 main office in Rochester, New York, with a view to replacing a formula 

 which we had not found entirely satisfactory. 



We are just in receipt of a letter from the Home Office advising that 

 your formula has been treated and found satisfactory and that from this 

 time on, they will discontinue the use of sheep in binding our reports and 

 will use our regular buckram treated with your formula. Heretofore, we 

 have been compelled to supply sheep bindings in districts where our buckram 

 would not stand the ravages of the insects. 



The Home Office states further that they are sending an advice to all our 

 subscribers throughout the United States, their possessions and foreign 

 countries, informing them of the change of binding and that it is due to 

 the success of a formula perfected by the Bureau of Science of the Insular 

 Government of the Philippines. Undoubtedly, this will be of interest to 

 you. 



With thanks for your great service, we remain, 

 Yours very truly.

 I have the honor to inform you that the result of the formula furnished 

 free by that Bureau for bleaching to me has been successful. Allow me 

 to express my sincere gratitude to you for this great favor. [Here follows 

 the formula.] Those solutions are good for 100 hats. 

 Very respectfully, 



Compositor de Sombreros, 



La Carlota, Negros Occidental, March 29, 1916. 

 I have the honor to advise you that Mr. J. E. Armstrong, sugar expert 

 of your Bureau, has been performing very useful work in my "hacienda," 

 where I have a modern mill equipped with vacuum pans, centrifugal pumps, 

 etc. As the handling of these apparatus and the modern process of ex- 

 tracting sugar cane juice are new in this country, * * * during his
