Lot No. 4. — This was dressed with twelve dollars' worth of De- 

 Burg's super-phosphate of lime, and produced 4,641 lbs., or 77-| 

 bushels per acre. 



Lot No. 5. — This was fertilized with super-phosphate of lime, at 

 half the expense of the foregoing, say six dollars per acre, and pro- 

 duced 3,637 lbs., or 60f bushels per acre.* 



Further Experiments on Potatoes. 



Two acres were planted on the Warren lot. This was dressed in 

 1853 with hog manure, at the rate of eight and one-third cords, and 

 about thirty bushels of coal-ashes to the acre. This year the land 

 received to the acre 400 lbs. of guano, applied in the hill. The 

 product was 359 bushels, or 179^ bushels to the acre. 



Lot below the House. — This also contained two acres, and had been 

 mowed for three years without any dressing. Last year (1853) the 

 land was broken up and cultivated with corn for fodder, without 

 manure. This year it received, like the Warren lot, 400 lbs. of guano 

 to the acre, and produced 379 bushels, or 189^ bushels to the acre. 



In all of the above cases the manure was applied in the hill.f 



ROOT CEOPS. 



Experiments on the Field by the Barn. 



The soil was a deep, good loam, ploughed from twelve. to fifteen 

 inches deep. The previous crop, in 1853, was ruta-baga turnips. 

 The fertilizers named below were compounded with meadow muck 

 as before stated, and were spread and deeply ploughed in, the cost 

 of each being at the rate of twelve dollars per acre. Each lot con- 

 tained twenty-eight square rods. 



CARROTS. 



Lot No. 1. — This was dressed with guano, and produced 6,35 t lbs., 

 or, at 55 lbs. per bushel, 115ff bushels, or 660 bushels per acre. 



'<■ The potatoes on lot No. 1 were small, but numerous and good. Those of 

 Nos. 2, 3, 4 and 5 were all large and fine for the table. 



t From these experiments, it will be seen that the results of these fertilizers in 

 the potato crop vary with the results in the corn crops. Dc Burg's super-phosphate 

 of lime, which produced the largest crop of corn, yielded the smallest crop of pota- 

 toes. Guano yielded the largest crop, even on land which had received 00 

 manure for four years, having been mowed three year.-, and last year cultivated with 

 corn for cut fodder. In this instance, ten dollars' worth of guano produced is:).', 

 bushels of superior potatoes per acre. Similar results in America and England 

 prove the value of this fertil/er, especially for potatoes.
