My dear Dana,—Well! “the books” have just come.

I suppose you are in no hurry for notices of them, and would prefer short ones....

I rather like to do such things incog., as in the “Nation,” in which I sometimes take a shot at this or that.

I and wife are well,—very.

Had a week in Old Oneida, which still looks natural. I am grinding away at “Flora,” and probably shall be found so doing when I am called for.

Very well! I have a most comfortable and happy old age. Wishing you the same,

Yours ever,
A. Gray.
