Rainfall at Fort Worth.
AN inspection OF the government re-
ports on Texas metcrology shows an
average annual rainfall at Fort Worth
Of Al plus inches. This average how
ever. is based on fragnontary observa-
tions made during 1889, 1850, 1851 1852,
and again In 1855. 1883. 1890 ana 1891
Both Of these sets OF observations
cover only years manirestly having far
above the average rainfall all over the
state.
IRON study OF rainfall records kept
at other towns in the state. all near
Fort Worth, 1t seems reasonable to
state that Fort Worth has a maximum
of about So inches and II minimum
rainfall Of about ~ inches annually.
These two figures would average 50
inches, but so inches is probably nearer
correct
