24:2 TALKS ON MANURES. 



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

 per acre.

You will see, that though the plot which has received 42 tons of 

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

 except 100 Ibs. of ammonia per acre, produced a crop equally good. 

 "How much increase do you get from 50 Ibs. of ammonia," 

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

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

 cost 20 cents a lb. In the above experiment, 50 Ibs. of ammonia, 

 costing $10, gives an increase of 16g- bushels of barley, and nearly 

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

 will cost 48 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 2a., 50 Ibs. of ammonia and 3| cwt. of superphosphate, 

 give 8,437 Ibs. of grain, equal to 71| of our bushels per acre. 



On plot %a.a. 100 Ibs. of ammonia and 3 cwt. of superphosphate, 

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

 acre, and nearly 2 tons of straw. 



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

 same plot, with the same manure, produced 66 bushels of dressed 

 grain per acre, weighing 53^ Ibs. to the bushel, or a total weight of 

 3,696 Ibs., equal to just 77 of our bushels 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 

 Ibs. of grain, or less than 61 of our bushels of barley per acre." 



The Squire happened in at this time, and heard the last remark. 

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

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

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

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

 Ibs. to the bushel." 



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

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

 they would pay $1.10 per bushel for good bright barley weighing 

 48 Ibs. per bushel, and for each pound it weighed less than this, 

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