If we compare the analyses of the soils and rocks below and above the bands of lime- 

 stone which traverse the State from the Hudson river to Blackrock upon Lake Erie, we 

 can scarcely fail to recognize the fact, that so far as composition is concerned, they are 

 belter adapted to the growth of the cereals than the limestones and their soils. This we 

 deem an important point — one which must operate in the selection and choice of farms, 

 and which must also tlirow some light on the mode by which the limestone soils may be 

 cultivated to the best advantage.
