10 BOARD OF AGRICULTURE. 



In the first experiment, the cost of turnips per bushel, 9 3 10th cts. In the 

 eecoiid experiment, the cost of turnips per bushel, 17 cte. 



Experiment lesttng the comparative value of Peruvian Guano and Coc's Super 

 Phosphate of Lime in the production of Strap Leaved Turnips. 



The ground upon which this experiment was tried, is a gravelly loam, about 

 cfghteen inches deep; Ijing nearly level, underlaid by a compact liavd nan, 

 and having no artificial drainage, it is rather heavy though not very wet. 

 It baa been in beets, carrots and turnips three years. The whole piece was 

 treated precisely the same, except in the application of fertilizers. The ex- 

 periment was tried upon G7 square rods of ground, hut for the purpose of 

 making the result more readily appreciated, the cast is for one acre of each 

 kind of fertilizer. 



One acre dressed with 555 lbs. Coe's super pliosphate, at 2 1-2 cts. per Ih., 

 or total cost of l|!l3.87, producing 835 bush, turnips, at a cost for this fertili- 

 zer of 1 4-7tli8 per busliel of turnips. 



One acre dressed with 733 lbs. guano, at 3 1-2 cts. per lb., or total cost of 

 $25.65, produced 82G bushel of turnips ; at a cost, for tljis fertilizer, of 3 

 1-lOtli cts. per bushel of turnips. 



The guano produced a luxuriant growth of top, and a good crop of buU)3 

 of large size. The phosphate gave less top with a greater yield of very fair roots. 



Mr. Chamberlain submitted the following report of experiments 



in the use of Fertilizers : 



May ZOlh, 1861. Planted western flat corn, one and a half bnsliels on a 

 half acre, in drills live to a rod. Manured lightly with stable manure, evenly 

 spread and harrowed. Put Coo's super phosphate in the drills at the rate of 

 200 lbs. per acre. 



Marked four rows 22 yards long, two of them having the super phosphate, 

 one having in it a half bushel of granite, burned and broken, the remaining 

 row wiih no dressing in the furrow. Shown thus, with the result: 



Row with phosphate, 250 lbs. ; row with granite, 214 lbs.; row with no 

 manure, 185 lbs. ; row with phosphate, 261 lbs. 



Taking the average of tiie product of the two rows having the phosphate, 

 and the excess over the row with no manure, shows a result of seven tons in 

 green fodder per acre for the use of two cwt. of phosphate. 



But little reliance should be placed upon the result of one experiment with 

 granite as a fertilizer. In this case, the amount of fodder in a row 22 yards 

 long, clianeed to he 29 lbs. more than that of a row on one side without 

 manure, and 30 lbs. less than a row on the other side having super phosphate. 



With the l)tst phase of the case, the ficnefit to the crop froui the application 

 of 100 bushels of pulverized granite per acre, is the product of 5800 Uis. of 

 green fodder. But if beneficial in a degree for the first year, it may bo con- 

 tinuously so, when, as in this case, it is not reduced to fineness, but was 

 mostly in the form of very coarse sand. 



In the last week in May, 1861, I planted a piece to Jackson potatoes, 

 putting in the hill Coe's supi^r phosphate of lime, mixed with half its quantity 

 of gypsum. Left one row without any apjili^ation, and put in anotlii;r row a 

 hair bushel of granite, burned and broken to the condition of coarse sand. 



Result. The row witli nothing applied in t!ie hill, produced 4 3-4th bush- 

 els ; row with granite, 5 1 4th bus!). ; row with phosphate, 1 2 bush. 



Dr. J. C. Weston read the following paper on the topic assigned 

 at the session in 1861, viz : 



The Diseases of Vegetation. 



Numerous as are the maladies which afflict mankind, they are doubtless 

 almost equalled by those morbid affections which prey upon the vegetable
