Biltmore, N.C.June 19, 1893,Dear Sir Dietrich,It give me great pleasure to introduce to you Mr. John Muir, whose successful struggle for the reservation of about one-half of the western side of the Sierra Nevada has made him so well know to the friends of the forest in this country. Mr. Muir has made for himself opportunities of observation which have been used to give him a knowledge06173 of the Sierra unapproached by anyone else, and I am confident that his intimate acquaintance with the Geology, Botany and Forestry of the region will be of very great interest to yourself. The great Muir glacier in Alaska was named for him. In the confident hope that Mr. Muir will meet with the same kindness at your hands for which I owe you such sincere thanks, I am,Very sincerely yours,Gifford Pincho
