CONCLUSION. 
In this brief review it has been impracticable to touch on all that is of 
interest or importance in connection with the soils. Their physical con- 
dion, power of water absorption, percentage of humus, details of plant 
growth, and other particulars have had to be passed over almost without 
notice, but it is hoped that the presentation made will prove a start in the 
right direction and be followed by closer studies of the various soils of the 
State and a combined effort for such an understanding of our agricultural 
capabilities as will result in the rapid improvement of everything con¬ 
nected with the farming interest, which can be effected by agricultural 
geology or agricultural chemistry.
