 SOIL EXAMINATION. 

 The Dry-Farmer should dig a hole ten feet deep at several points of his 

 farm. The best soil for holding moisture is a deep, rich loam of uniform 

 texture : the worst is shallow and gravelly, or land broken by layers of 

 different soil strata. In the illustration the farmer has found limestone 

 underneath the black surface turf.
