He recommended the following combinations of chemi- 

 cals for fertilizers, the "bone black" containing 16 per 

 cent, phosphoric acid, the "muriate of potash" 50 per 

 cent, of actual potash, and the " sulphate of ammonia " 20 

 per cent, of nitrogen. 



( bone black, 325 lbs. } 



Comb'n for corn, < muriate of potash,100 lbs. > cost $11. 

 ( sulphate of ammonia, 75 lbs. )

( bone black, 300 lbs. ) 



Comb'n for oats, < muriate of potash, 150 lbs. > cost $8.50 

 ( sulphate of ammonia, 25 lbs. ) 



These combinations are for one acre where no manure 

 is used, and in case of corn and potatoes, 150 lbs. of each 

 is to be used in the hills, the remainder broadcast. 



More potash would have an injurious effect if injudi- 

 ciously used. He said that fertilizers were not stimulants 

 as much as necessary food for the land, as much so, if not 

 more, than manure is. 



His instructive and valuable talk was followed by that 

 of others of large experience in the use of fertilizers, who 

 agreed with the Professor in urging upon the farmers the 

 economy to them of manufacturing their own fertilizers. 



The 51st Institute was held in Peabody Institute, Dan- 

 vers, on March 11, 1887, on the subject of "Progress of 

 Ensilage," opened by Rev. O. S. Butler, of Georgetown, 

 who gave an instructive history'of it in this country, where 

 it only dates back to 1875, while in Germany and Prussia 

 it was preserved 100 years ago. He gave the opinions of 

 95 farmers, whose testimony he had collected, and their 

 general tenor was, that ensilage had come to stay, as a 

 permanent institution for the promotion of agriculture. 

 Samples of ensilage corn and ensilage cut in inch lengths 

 were shown. 



The afternoon Institute was opened by Francis H. 

 Appleton, of Peabody, on ' Encouragement of Tree Plant-
