222 LETTER-FILES OF S. W. JOHNSON 



I would like to add to the list you give : Prof. F. H. Storer, 

 Bussey Institution, Jamaica Plain, Mass. ; Dr. Ledoux, New 

 York City; Dr. E. H. Jenkins, New Haven, Conn.; Dr. H. P. 

 Armsby, New Haven, Conn. ; Mr. A. T. Neale, chemist to the 

 New Jersey Ag. Exp. Station — all experienced fertilizer ana- 

 h'sts. The discussion of the subject would be more satis- 

 factory if there were time beforehand for some experimental 

 work. I have some investigations in progress which can 

 hardly be complete early in July, but might be late in August. 

 ... I would add the names of Prof. G. C. Caldwell, Cornell 

 University, Ithaca, New York; Prof. Albert Chester, Hamilton 

 College, Clinton, Oneida Co., N. Y. ; Prof. A. Aubert, Maine 

 Ag. College, Orono, Me. Very truly yours, S. W. Johnson. 



(S. "W. J. TO Professor G. C. Caldwell, Director of 

 Cornell Experiment Station.)

 that a meeting of the members of the committee appointed at 

 Boston, viz., yourself, himself. Collier and Atwater be held 

 for between Sep. 15 and 30th. This would be very profitable 

 no doubt, and I write to ask you if you could come to New 

 Haven (where I will bed and board you) and at what time. 

 If you cannot come, that fact will decide me what next best 

 thing to do. I should like the meeting held nearer the 15th 

 than the 30th, Dr. Shepard has to go to So. Car. soon after 

 the 30th. 



But if you can come any time between these dates, let me 

 know. Yours most truly, S. W. Johnson. 



(S. W. J. TO Professor George H. Cook, Director of 

 New Jersey Experiment Station.)

My dear Sir, — It has been repeatedly on my mind that some 

 conference in respect to trade-values of fertilizers is desir-
