Eesults of experiments with fertilizers on wheat, C. E. 

 Thorne (p. 208). — In Ji brief note appended to the bulletin are stated 

 the general results of this j^ear's experiments with fertilizers on the sta- 

 tion farm. The details will be published in a future bulletin in connec- 

 tion with the results of similar experiments on corn and oats. "On 

 this farm, where by thorough drainage and tillage we have been able 

 this year to produce an average of 30 bushels of wheat per acre without 

 any fertilizer, no combination of commercial fertilizers has produced 

 sufficient increase of crop to pay the cost of the fertilizer, although 

 barn-yard manure has paid more than three times the cost of its appli- 

 cation."
