Mr. John Muir,
c/o The Outlook Co.. N.Y.

My dear sir:-

Not having your address, I am trying to reach you through the "Outlook" from the pages of which I have recently "been receiving enjoyment "by reading your articles on the Yosemite. When in California, and returning from the Yosemite, I stopped at the place where you were then living, hoping to meet you; but you were then, I think, in Alaska, and I lost that pleasure. I remember I left with you a letter of introduction from our mutual friend, Mr. Gifforci Pinchot.
I am now writing, not in regard to the Yosemite, but to ask if you might not be able to help me in an investigation I am now making as to the relative endurance of flesh eaters and flesh abstainers, by supplying me with your own experience. I am told that on your expeditions you are accustomed to live on hardtack and tea.

Can you refer me to any others who have had experience with a fleshless diet, whether or not it has been a successful experience?
If you are at all interested in these subjects you probably have seen the extensive work on nutrition which my colleague, Professor Chittenden, has been doing here at Yale, and which has quite overturned the theories of Atwater and other physiological chemists.
Hoping that you can aid me without too much inconvenience, I am

Yours very truly,

Irving Fisher
