242 TALKS OX MANURES. 



The 14 tons of farm-yard manure produce nearly 56^ bushels 

 per acre.

You will see, that though the plot which has received 43 tons of 



manure per acre, produced a splendid crop ; the plot having nothing 



except 100 lbs. of animouia per acre, produceil a crop equally good. 



"IIow much increase do you gtt from 50 lbs. of ammonia," 



asked the Deacon, " and how much from 100 lbs. ?"

If you buy nitrate of soda at 3} cents a lb., the ammonia will 

 cost 20 cents a lb. lu the above experiment. 50 lbs. of amuioiiiu, 

 costing |10, gives an increase of IGjj bushels of barley, and nearly 

 half a ton of straw. If the straw is worth |4.00 per ton, the barley 

 will cost -18 cents a bushel. 



Double the quantity of manure, costing $20, gives an increase of 

 28 bushels of barley, and over one ton of straw. In this case the 

 extra barley costs 57 cents a bushel. 



On plot 2 I., 50 lbs. of ammonia and 3* cwt. of superphosphate, 

 give 3,437 lbs. of c^rain, e(iual to 7H of our bushels per acre. 



On plot 2<i.'i. 100 lbs. of ammonia and 3^ cwt. of superphos hate, 

 give 3,643 lbs. of grain, which lacks only 5 lbs. of 76 bushels per 

 acre, and nearly 2| tons of straw. 



"That will do," said the Dea-on, " but I sec that in 1857, this 

 same plot, with the same manure, produced 6Gi bushels of dressed 

 grain per arre, wciirhing 53A lbs. to the bushel, or a total weight of 

 3,690 lbs., equal to just 77 of our bu.sliels per acre." 



" And yet," said the Doctor, " this same year, the plot which 

 had 84 tons of farm-yard manure per acre, produced only 2,915 

 lbs. of grain, or less than 61 of our busliels of barley per acre." 



The Squire happened in at tliis time, an<l heard tlie last remark. 

 " What are you saying," he remarked, " about only 61 bushels of 

 barley per acre. I should like to sec such a crop. Last year, in 

 this neighborhood, there were hundreds of acres of barley that did 

 not yirld 20 bushels per acre, and very little of it would weigh 44 

 lbs. to the bushel." 



This is true. And t lie maltsters find it almost impossible to get 

 six-rowed barley weighing 48 lbs. per bushel. They told me, that 

 they would pay fl.lO per bushel for good bright barley weighing 

 48 lbs. per bushel, and for each ponnd it weighed less than this, 

 they deducted 10 cents a bushel from the price. In other words,
