“The amount of rain that falls is aston
ishing. It is said to average P2B inches
per annum. This, when compared with
the small rainfall of Egypt—nine inches
per annum —where M. de Lessepa built
liis ditch through the sands of Suez, is sug
gestive.
“When the rains come in early and reg
ularly, it means a fair, healthy wet season
—that is, of course, for the Isthmus.
When the rains are irregular or late, it
means a sickly season, and in the hot days
between rains yellow fever develops case
after case. Then the raias come on. and
there is a marked diminution in the num
ber of eases. Again, after hot, sunny days
without rain, anew crop of yellow fever
cases results.
