In connection with our letter of July 12, 1912, requesting a compound 

 for re-inking planotype ribbons and formula submitted in your letter of 

 August 26, 1912, I wish to advise you of the results of this work. 



One-quarter bottle of the solution was purchased at a cost of 'P5.88 which 

 was sufficient for re-inking six of the ribbons. It will be noted therefore 

 that the cost per ribbon is f*0.96 — slightly over 10 centavos per meter — for 

 re-inking, exclusive of labor which is a negligible item in view of the fact 

 that the messengers were employed for the work during otherwise spare 

 time. New ribbons cost ?2.63 each for the cheapest grade employed and 

 ?=3.94 for a more expensive grade. The fabric, after being used thoroughly 

 is not damaged and the re-inking has been done with success. The ribbons 

 were finally dried after re-inking and are fully as satisfactory for ordinary 

 use as are the original purchases. 



This information may be of interest to you. 

 Very respectfuly,

 Mr. Armstrong, of your Iloilo office, spent the day with me on my 

 hacienda on his way to Isabela. He made several analyses of cane and 

 sugar which benefited me and I am pleased to say that I appreciated his 

 services. 



I hope that you will allow him to come back again when convenient. 

 We have several haciendas and need occasionally a look-over of a good 

 practical man like Mr. Armstrong. 



Thanking you, I am, yours truly,

 for or a use for. * * * 



You may be interested in knowing that the samples of hydrated lime 

 you recently analyzed for us brought us a Manila order for 400 tons. 

 Thanking you for any information you may have re silica, we are,

We returned from Mindoro yesterday on the Malccon. I wish to thank 

 you for the trouble you have gone to on my behalf, in helping me with my 

 transportation difficulties. Had it not been for your timely assistance I 

 would have experienced great trouble and delay in obtaining a steamer 

 suitable for my work. 



Please accept my appreciation of your policy of fostering the develop-
