TliPsf arc all thi' Ajj^ins I will InuiliI • you with. The "niixiHl 

 mim-rul nmmirt's" coiisipteil of su|MTiiho.sphalf of lime (composi'il 

 of 150 lbs. bone-a.sli and I'M lbs. sulphuric acid, sp. gr. 1.7), ;]U(J lbs. 

 sulphate of |M»ta8h. 200 lbs. sulphate of soda, and 100 lbs. sulphat.- 

 if njai^ncaia. The anuiu)nia-.>iulls consisted jf cciual parts sulphate 

 and muriate of ammonia, eonlnining about 25 per cent, of ammo- 

 nia. The manuri s were sown as early as p(»ssible in the sprint;, 

 and, if the weather was suitable, st)mctimes in February. Tiie 

 farmyard-manure was spna 1 on the*lanil, in the first year, in the 

 .'^priiiL', afterwards in November or December. The hay was cut 

 froui the middle to the last of June; anil the aftermath was pas- 

 tured olT by sheep in October. 



" II is curious," said the Deacon, " that 400 lbs. of ammonia-sjilts 

 should give as jn^-al an inerca.se in the yield of hay the fii-st year 

 as 14 tons i»f farmyard-manure, but the second year tin- farmyard- 

 mau'.ire comes out ileeidedly ahead." 



"Tije fannyanl-manure," .s;iitl I," was applieil ever}* year, at the 

 rite of 14 u'ross tons per acre, for eii:ht years — \H'}i] to 1H(;;J. After 

 186;{, this pU)t wa« left williout manure of any kind. The averai^e 

 yield of this plo*. durini: the lii-sl 8 years was 4,s00 lbs. of hay per 

 acre. 



On the plot dressi'd wUh 14 tons of farmyard-manure and 200 

 lbs. ammonia-Sidts, the average yield of hay for 8 years was 5,544 

 lbs. \tor acre. Aft<T the eighth year the farmyard-manure was dis- 

 continued, and during the next twelve years tlie yield of hay 

 averaged 3,683 lbs., or 1,14"J lbs. more tlian the continuously unma- 

 nured plot. 



In 18.5!), superphosphate of lime was used alone on plot 3, and 

 has been continued ever since. It scenes clear that this land, which 

 had been in pasture or me idow for a hundred years or more, was 

 utjt deficient in phosphates. 



'' It does not seem," said the Deacon, " to have been deficient in 

 anything. The twentieth crop, on the continuously unmanured 

 plot was nearly IJ ton per acre, the first cutting, and nearly |-ton 

 tiie second cutting. And apparently the land was just as rich in 

 1875, as it was in 1850, and yet over 25 tons of hay had been cut 

 and nmared from the land, without any manure being returned. 

 And yet we are told that hay is a very exhausting crop.'" 



"Superphosphate alone," .said the Doctor, "did very little to 

 increase the yield of hay, but superphosphate and ammonia jiro- 

 duced the first year, 1859, over a ton more hay per acre than the 

 siip<rphosphate alone, and when poVish is added to the manure, the 

 yield is still further increased."
