 Europe.

 gleaning that are under way, and, in the 

 enumeration, have shown how each phase is, 

 in the main, sectional. However, this is true 

 only in a broad way. There is no county, no 

 township in the length and breadth of the 

 country that does not present examples of one 

 or more of these various phases. Drainage 

 and clearing are common to all sections, and 

 the specialization of crops as well. Even irri- 

 gation and the best practices of dry-farming 

 are traveling east. New Jersey has come to 

 realize in the last few years that its acres cannot

Having considered the reclamation move-

 and determine approximately the ultimate do-
