MAP II. — IRRIGATION IN THE WEST AND NORTH-WEST OF 



ARGENTINA. 



Extent of the irrigations in the north {zone of the great summer rains), and the 

 south {glacier zone). The historic industry of fattening cattle in the invernadas 

 and the export of cattle to the Andean regions only survive in part. On the 

 other hand large modern industries have developed at Tucuman, Jujuy {sugar- 

 cane), Mendoza, and San Juan {vines), and they supply the Buenos Aires 

 jnarl^et.
