Dear Sir,

I am directed by the
Chief Signal Officer to request that you
will send him the original weather maps
or charts prepared by you last fall in
Chicago when performing your duties of
forecasting the weather of the Lake-region.
He also desires to know if any action has yet
been taken by you in relation to the meteoric
effects of the great fires in the Northwest.

Very respectfully &c [etc]
