EXPERIMENTS ON WHEAT. 213

" I do not quite see that," said the Deacon, " the farm-yard ma- 

 nure gave an increase of nearly 20 bushels per acre. And the quality 

 of the grain must have been much better, as it weighed 3 Ibs. 

 per bushel more than the plot unmanured. If the wheat doubled 

 in price, as it orght to do in such a poor year, I do not see but that 

 the good farmer who had in previous years made his land rich, 

 would come out ahead." 



" Good for the Deacon," said I. " ' Is Saul also among the 

 prophets ? ' " If the Deacon continues to study these experiments 

 much longer, we shall have him advocating chemical manures and 

 high farming ! 



The eighteenth season (1860-1,) gave less than 11-J- bushels per 

 acre on the unmanured plot ; and nearly 35 bushels on the ma- 

 nured plot. 



The mixed mineral manures, gave nearly 15^ bushels.

When we consider that this is the twentieth wheat-crop in suc- 

 cession on the same land, these figures are certainly remarkable. 



" They are so," said the Deacon, " and what to me is the most sur- 

 prising thing about the whole matter is, that the plot which has had 

 no manure of any kind for 25 years, and has grown 20 wheat-crops 

 in 20 successive years, should still produce a. crop of wheat of 17 

 bushels per acre. Many of our farmers do not average 10 bushels 

 per acre. Mr. Lawcs must either have very good land, or else the
