SECRETARY'S REPORT. 23 



Lot No. 2. — This was dressed with Mapes' super-phosphate of 

 lime, and produced 5,50-3 lbs., or lOO-j^ bushels, or a fraction less than 

 572 bushels per acre. 



Lot No. 3. — This was fertilized with De Burg's super-phosphate of 



lime, and produced 5,630 lbs., or 102 T 4 T bushels, or a fraction less 

 than 585 bushels per acre. 



Lot No. 4. — This was dressed with potash, and produced 6,046 lbs., 

 or about 110 bushels, or at the rate of 628 bushels per acre. 



Lot No. 5. — This was manured with barn manure, and produced 

 7,255 lbs., or 131-j^ bushels, or at the rate of 753 bushels per acre. 



Experiments were also tried on two and a-half acres of old carrot 

 ground, upon which this root had been grown for seven years — soil 

 a light loam, ploughed ten inches deep. 



Five-sixths of an acre was dressed with eighteen dollars' worth of 

 potash, dissolved and mixed with sixty bushels of coal ashes. The 

 product was 500 bushels, or 600 bushels to the acre, of as fine carrots 

 as were ever seen. 



One and four-sixths of an acre was manured with reservoir manure, 

 estimated at its comparative value with barn manure, (say 8^ cords to 

 the acre.) The product was 900 bushels, or 540 bushels to the acre, 

 but the carrots were neither as large nor long as those dressed with 

 the potash and ashes. 



From these experiments we learn that the various manures arrange 

 themselves as to their productive energy in the following order, the 

 cost of each being twelve dollars to the acre : — 



Barn manure produced, of carrots, . . 753 bushels per acre. 



Guano, 660 " 



Potash, 628 " 



De Burg's super-phosphate, . . . 585 " 



Mapes' " " 572 " 



Reservoir manure, ..... 540 " 



The parsnip and onion crops were nearly a failure, occasioned by 

 stagnant water on the land soon after sowing. 



Of ruta-baga and . other turnips, there were four acres, producing 

 1,119 bushels, or 279f bushels per acre. These were manured with 

 barn-yard manure, at the rate of 8£ cords to the acre. 



The farm also produced crops of pease, beans, tomatoes, cabbages, 

 beets, pumpkins, squashes, and other vegetables ; apples, pears, 

 quinces, and other fruits, most of which have been consumed from 

 time to time on the premises, and of which the statistics need not 

 here be given.
