820 BOARD OF AGRICULTURE. 



at the rate of thi-ee hundred pounds per acre. At the time of harvest- 

 ing, two square rods of this rye, manured with guano, and weighed 

 with the straw, produced forty-seven and ^°^ pounds. After drying 

 and threshing, the product was eight quarts of rye, and thirty pounds 

 of straw, equal to twenty bushels of grain, and tAventy-four hundred 

 pounds of straw per acre. Two square rods not manured, produced, 

 at harvesting, twenty-eight pounds, including straw and grain, and, 

 after drying and threshing, five quarts of rye, and sixteen and -Jfjj 

 pounds of straw, equal to twelve and one-half bushels of grain, and 

 thirteen hundred and twenty pounds of straw the acre. Estimating 

 the rye at one dollar a bushel, and the straw at eight dollars a ton, 

 the produce of the land, manured with guano, would come to twenty- 

 nine and ~g- dollars the acre ; the produce of the land, which was left 

 without guano, would come to seventeen and y^j"^ dollars the acre, 

 leaving a difference in favor of the guano of eleven and -^W dollars 

 per acre. The cost of the guano per acre was nine dollars, which, de- 

 duct from eleven and -^^^^ dollars, leaves a net profit on the lot 

 manured with guano, of two and -^^^ dollars per acre. 



The committee manured a piece of rye in the old house lot, upon 

 the same plan as the lot just described. The two rods, manured with 

 guano, pruduced fifty-one and -fjf-g pounds of straw and rye at har- 

 vesting, and the two rods left without manure, produced, at harvesting, 

 including straw and grain, thirty-two and ^^^^ pounds. 



Comparing these lots Avith the other west of the barn, the two rods 

 manured produced at the rate of thirty-one and -^^\ dollars the acre ; 

 the two rods without manure produced at the rate of twenty and -j^g^g- 

 dollars the acre, a difference in favor of guano, of eleven and -f'^'^y dol- 

 lars ; deduct nine dollars, the cost of the guano per acre, leaves two 

 and /gij dollars net profit on the guano per acre ; averaging the two 

 experiments, the net profits on manuring with guano would be two 

 and jo^^ dollars to the acre. 



There was sown, in April, upon a lot of land west of the house, 

 one acre of wheat ; it was manured with ten cart loads of poor com- 

 post, worth fifty cents a load, and three hundred pounds of guano, 

 costing nine dollars, all spread broadcast, and ploughed under. The 

 produce of the acre was twenty bushels of good wheat. 



In the estimation of the committee, if twenty cart-loads of barnyard 

 manure had been spread upon this land, costing twenty dollars, the 

 increase in the crop would have been little, if any ; if so, this trial 

 shows a difference in favor of guano, of six dollars an acre. The 

 committee tried an experiment by sowing guano broadcast at the 

 rate of three hundred pounds the acre, on a lot of grass land east of
