Ascending still further to the region between 20 deg. and 25 deg. north latitude,
and 15 deg. and 45 deg. west longitude, which borders, in part, on the S. W.
corner of the desert, and we have not, during the month of August, a
single wind between S. S. E. and W. N. W., which blows in upon the land;
and _only twelve instances out of three hundred and ninety-four in this
hottest month in the year, and on the southern portion of the desert, when
the wind blows on shore from any quarter_. This is demonstration. The
monsoon winds are confined to the rainy belt; they do not reach the
desert, nor does the desert attract the winds from the ocean, or
reverse, hold back, or disturb the trades.

Ascending once more, to the region between the degrees of 25 and 30, north
latitude, and 15 and 45, west longitude, we find it bounded east entirely
on the center of the desert. Now
