SOME PECULIARITIES IN THE RAINFALL OF TEXAS. 59 
In the coast region of Texas, say such part as lies within 
200 miles of the Gulf of Mexico, the rainfall regime is that 
which has been elsewhere classified by me as the Gulf type. 
In this type the average rainfall during the months of Au¬ 
gust, September, and October is far above the amount which 
would occur if the distribution was equable through the en¬ 
tire year. In September, the maximum month, about one- 
sixth of the rain of the year may be expected, while in the 
minimum month, April, not more than a twentieth, or even 
much less, of the annual precipitation usually falls. At Key 
West, Florida, which affords the best example of this type, 
not less than 15 per centum of the annual precipitation occurs 
in September, while in March only 2 per centum may be 
expected. The increase in rain is steady from March to 
September, whence an unbroken decrease obtains to March. 
The Gulf type is best represented by Brownsville, although 
the rainfall curves of Galveston and Indianola substantially 
accord therewith. On the diagram herewith, in thousandths
