MANURES. 197 



and their worth to the present crop, I pUiuted four rows with- 

 out any fertilizer, (Lot No. 1 ;) the product of this lot was 

 147|^ lbs. of broom-brush, and 9 bushels of seed, at 28|^ lbs. per 

 bushel. 



Lot No. 2, four rows Avith ashes in the hill, yielded 162| lbs. 

 brush and 11| bushels seed, 28 lbs. per bushel. 



Lot No. 3, four rows with guano in the hili, yielded 223| 

 lbs. brush and 14| bushels seed. 



Lot No. 4, four rows with stable manure ploughed in, yielded 

 232 lbs. brush and 15-| bushels seed. 



The yield of Lot No. 2, in excess of Lot No. 1, is 15^ lbs. 

 brush and 2^ bushels of seed ; reckoning the brush at 5 cents 

 per lb. and the seed 1 cent per lb., leaves a balance of $1.40 as 

 the worth of the ashes, 6| lbs., or 21|^ cents per bushel. 



The yield of Lot No. 3, in excess of Lot No. 1, was 16^ lbs, 

 brush and 5^ bushels seed ; leaving a balance of $5.18 as the 

 worth of 81 lbs. guano, or Q-^^ cents per lb. 



The yield of Lot No 4, in excess of Lot No. 1, was 85 lbs. 

 brush and 6} lbs. seed ; leaving a balance of $5.81 as the worth 

 of 3| loads or 113 bushels manure, or $1.55 per load of 30 

 bushels. 



I do not claim for these experiments perfect accuracy in 

 every particular, yet great pains were taken, and I consider the 

 figures, stating the amount of crop from the different lots, 

 correct. 



I would here state that the brush on Lot No. 3 was not cut 

 until a few days after the others, and being exposed to more 

 frosts, the weight of the brush was diminished probably 5 lbs. 

 per cwt., which would give a still more favorable account of the 

 effects of the guano. 



If the manure had been applied in the hill, it would probably 

 have produced a heavier crop, Ijut its permanent effects will 

 probably counterbalance this loss. The ashes and guano, I 

 think, have spent themselves on the present crop. 



If this experiment is an approximation to the truth, it Avill be 

 seen that the guano is far better worth what it costs than cither 

 stable manure or ashes. 



It will be conceded by all, I think, that manure from fatten- 

 ing cattle costs at least $1.50 per load of 30 bushels at the
