zone midway between the extremely dry and the 
extremely humid portions. The irregular distribu- 
tion of the precipitation, the late spring and early fall

Mexico it is the only method of agriculture that can 
be made to reclaim avery large portion of the country.

inches, but irregularly distributed and under a tropi-

adapted as to make dry-farming successful in Brazil,
