 conducted, will enable the farmer to understand the 

 wants of his land, so as to proceed intelligently in sup- 

 plying them. These trials may be, for the most part, 

 accomplished in one season, but require for the best 

 and the most assured results a longer period. The 

 most important experiments may be consummated, 

 and the most essential information acquired in a single 

 year ; while other results may be added, and those of 

 the first season verified or corrected, by trials contin- 

 ued through a series of subsequent years. 



The farmer who is accustomed to experimenting 

 on a limited scale, with reference to but one, or a few 

 points of inquiry, does not perhaps realize how greatly 

 the results may be enlarged, with but little extra labor. 

 By introducing additional elements into the investiga- 

 tion, and by properly combining them, the effects may
