192 THE PLAIN OF THE PAMPAS 



those of the Central Argentine have met, and the wheat 

 has invaded the whole of the San Martin department. 

 It extends even south of the old colonies of the Central 

 Argentine toward the south-west of Santa Fe, in the 

 General Lopez department. 



The 1908 Census shows a very different state of 

 things. The density of the wheat-cultivation has 

 continued to grow appreciably in the whole of the 

 northern region, and also in the south-west of the 

 province, at some distance from the Parana (General 

 Lopez department). On the other hand, it has been 

 reduced in the adjoining district of Rosario (depart- 

 ments of Iriondo, Belgrana, Caseros, and Constitution), 

 where maize-growing has developed. Maize has won 

 part of the wheat belt. 



Restricted in the south by the extension of the maize 

 belt, the region of the colonies has now a very distinctive 

 character amongst the agricultural areas of the Pampa. 



1 The names of departments which belong in their entirety to 

 the maize region are given in italics. The department of San Jeronimo 

 straddles the maize region and the region of the colonies. The General 

 Lopez territory also extends, in the south-west, far beyond the limit 

 of the maize belt.
