The reader is requested to make a careful study of the tables and of 

 the results obtained from the different plats. Plat No. 34 grew spurry 

 in 1896 and the crop was plowed under. The spurry reseeded itself 

 and was plowed under the second time. It reseeded again, and was 

 allowed to remain as the cover crop during the winter of 1896-7. 

 No crop was removed from the plat in 1896. Upon all the other 

 plats forage crops were grown in 1896 (see Cornell Bulletin 135.) 

 Plat 34 responded to the better treatment by producing a total of 384 

 bushels per acre. 



Attention is called to the results on plats 37 and 38. These two 

 plats were treated alike in every way, except that at the last time of 

 cultivating plat 37 was left level and plat 38 was hilled. The result 

 shows a yield of 37 bushels more per acre on the plat left level than 

 on the plat hilled. If in any season the hilling would have shown 

 good results it should have been during the present season. Rain 

 was abundant, and at no time during growth was it apparent that the 

 plants were suffering because of lack of moisture. The reason ordi- 

 narily given for hilling potatoes is that it is done to keep tubers from 

 growing out of the ground and becoming sunburned. If the land 

 be properly fitted and the planting properly done the potatoes will not 

 grow out of the ground. On the plat where level culture was
