          I have been obliged to remain
in Washington on account of the
printing and making up of our annual
Report. The publication
of a quarto-volume of  Presentations,
an 8vo [octavo] volume of a Report;
the preparation of an annual
contribution to the patent office,
besides four or five thousand
pages of letters, keeps me somewhat
busy.

I shall hope to see you while
at the [north?] and to settle some
thing definitly as to the plants of the
exploring expedition.

I remain as ever
Truly you friend
