be allowed to heat, neither must they be allowed to become dry. 

 If planting is done very early in the spring the ridges may be 

 permitted to remain for ten daj^s to two weeks before harrowing 

 down. If planting is done somewhat late the ridges should be 

 harrowed within one week after planting. In the case of the early 

 planting there is usualh'- enough moisture present so that the 

 ridging may temporarily prove a benefit by enabling the soil to 

 become warm. In the case of late planting all the moisture 

 should be conserved, and this is best done by leveling the 

 ridges. Where the soil is naturally too wet the ridges may 

 be beneficial in that they hasten evaporation and the consequent 

 drying of the soil. 



Several causes contributed to the low yield on the acre field, 

 chief among which were seed which had become weakened in 

 vitality thus necessitating replanting, late planting, excessive 

 drought in July, followed by excessive rains. While the land had 

 been receiving fairly liberal applications of manure and was in a 

 good state of fertility, yet the causes above mentioned conspired to 

 produce but little more than half the crop which should have 

 been produced under favorable conditions.
