On the ends of the mulched plat the moisture ran 

 considerably higher than on the checks . In the corn during 

 the dry v/eather, the moisture content ran nearly as low as 

 the calculated normal. There was thus considerably more 

 water used by the plants, which was reflected in the lar- 

 ger yield, Dxoring the most trying period of the drought 

 the corn on this plat seemed to suffer nearly as severely 

 as on any of the plats. The nitrogen content was greatly 

 lowered, as well as the moisture.
