Madison June 8th /63 Dear David, I write to tell you not to go to Watsons as I mean to start out upon a long botanical and
geo- logical tour down the Wis river valley and over into Iowa etc so that I do not know when I shall be home. If I go to
Mich University Med 'School I shall be with you untill Oct' When I do return from my tramp I am not so well as I was last
term - I need a rest - perhaps my tour will do me good though a three or four hundred mile walk with a load is not at least
in appearance
