EXPERIMENTS ON WHEAT. 213 



" I do not quite see that, 1 ' 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 urimanureJ. If the wneat doubled 

 in price, as it ought 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." 



" Gooil 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 \\\ 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 ia 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 fanners do not average 10 bushels 

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