1858.] SENATE— Xo. 4. 213 



Jenny Linds produced 309 bushels of sound, large potatoes, being 

 103 bushels per acre. One acre of Riley or Dover potatoes produced 

 80 bushels of good potatoes. One acre of long reds produced 100 

 bushels of sound but rather small potatoes. 



All the 10 acres alluded to above were manured with liquid manure 

 from the reservoir, at the rate of 85 loads per acre, ploughed in, and 

 200 lbs. of gypsum per acre, in the hill. Two acres planted with 

 Jenny Linds received 165 lbs. of gypsum only per acre, in the hill. 

 Three acres in all were planted Avith this variety and manured as 

 follows : One acre with liquid manure and gypsum, and two with 

 gypsum only. The two manured with gypsum only produced seven 

 bushels per acre less than that manured with liquid manure and 

 gypsum, but the tubers were much larger. The land was of equal 

 fertility, but the two acres which received gypsum only, were more 

 elevated, and consequently dryer. Two acres of Davis seedling, in 

 another field, manured with 300 lbs. of Coe's super-phosphate per 

 acre, in the hill, produced 87 bushels per acre of fine tubers. 



Cakrots. — Five acres were sown on the plain lot, and the yield 

 was 1,800 bushels, an average of 360 bushels per acre. All this land 

 had been planted with corn the three previous years. Three acres 

 had received yearly 8-^ cords of manure per acre. One acre had been 

 dressed Avith guano and one with potash for three years. This year 

 each acre received 85 loads of liquid manure, except a strip 18 feet 

 wide across the end of each of the three acres. This strip received 

 no manure of any kind this year. In addition to the liquid manure, 

 each acre received 11 cords of best barn cellar manure, ploughed in 

 to the depth of 12 inches. 



Acre No. 1, which has been dressed yearly with 8j cords of manure 

 previous to this year, and 85 loads of liquid manure and 11 cords of 

 barn cellar manure the present year, yielded 430 bushels. 



Acre No. 2, heretofore dressed with guano, and manured this year 

 like acre No. 1, yielded 380 bushels. 



Acre No. 3, previously manured with potash, but dressed like the 

 two above named this year, yielded 400 bushels. 



The strip of land alluded to above, comprising but a portion of 

 each of the above three acres, yielded as follows : That portion 

 previously manured with guano produced at the rate of 180 bushels 

 per acre. 



That portion dressed in former years Avith potash, gave at the rate 

 of 288 bushels per acre. 



The portion Avhich had received manure gave at the rate of 300 

 bushels per acre.
