and the men aud localities for experiments were selected by^my assis- 

 tant, Ml. F. S. Coolej', acting in co-operation with the presidents of 

 societies addressed. In a number of cases these gentlemen expressed 

 a willingness to undertake the experiment upon their own farms and 

 whenever these were found to contain suitable soil selection was made 

 accordingly. In every case except two, Mr. Cooley had the opportu- 

 nity to make a personal inspection of the land before selection was 

 made, and the further very important advantage of personal explana- 

 tion of the objects and methods of the experiment to the party selected 

 to carry it out. The following is a complete list of the localities and 

 owners of farms on which an experiment was undertaken : Yarmouth, 

 John Simpkins ; fittsfield, O. T. Benedict; Lexington, A. G. Doug- 

 las; Marblehead, VVm. S. Phillips, Jr. ; Shelburne, Dole Bros. ; West- 

 field, C. F. Fowler ; Hadley, L. W. West ; Freetown, S. P. Richmond ; 

 West Bridgewater, J. C. Swan ; and Worcester, Pliny Moore. 

 Besides these a similar experiment was carried out upon the station 

 grounds in Amherst. 



In accordance with the conclusions of the conference already 

 briefly stated, the plan of experiment was as follows : 



1. Area occupied by each 1 acre; if circumstances permitted of 

 the following dimensions.: length 213 feet 4 inches, width 204 feet. 



2. Plots — fifteen in number, each 204 feet long and 10 feet and 

 8 inches wide, containing one-twentieth of an acre. In each plot 

 three rows. 



3. Strips between and also outside experimental plots — length, 

 204 feet ; width 3 feet 4 inches. In the middle of each strip one row. 



These fifteen plots and the strips make within 10 square feet of an 

 exact acre. As a matter of fact few of the experiments were laid 

 out exactly upon these dimensions ; but the principle of arrangement 

 was the same in all and most approached these proportions quite 

 closely. 



4. The treatment of the several plots was as follows : 

 No. 1. Nothing. 



" 2. Nitrate of soda. 



" 3. Dissolved bone-black. 



" 4. Nothing. 



" 5. Muriate of potash. 



" 6. Nitrate of soda and bone-black. 



" 7. Nitrate of soda and muriate of potash. 



" S. Nothing.
