No. 9. On Indian Corn. 

 [1791.] Eight acresof Indian corn were planted in a black 

 boggy earth, from three inches to ten deep, over a fpungy wet 

 bottom of ftiff red clay, intermixed with fmall pebbles of iron 

 ore. The whole was manured in the hills with long litter and 

 liable dung ; to four acres of this manure, was added at the 

 firft hoeing, a table fpoonful o^Gypfum to a hill, two acres were 

 manured with pulverized oyfter fliells — three rows with afhes, 

 three with pounded bones — a half pint of each to a hill — three 

 with a fpoonful of fait ; the remainder of the field had no other 

 manure than the dung. The fheep breaking in eat all the faked 

 hills, and damaged thofe manured with bones fo much as to de- 

 feat the experiment ; the remainder of the field was fo much 

 alike as to enable me to draw no inference from it in favor of 

 either of the manures; from thence I am led to infer, that upon 

 this rich wet foil they are of no ufe. 



No. 10.
