“Dear Mr. President:
I am anxious that the Yosemite National Park may be saved from all sorts of commercialism & marks of man's work other than the roads, hotels, etc., required to make its wonders & blessings available. For as far as I have seen there is not in all the wonderful Sierra, or indeed in the world, another so grand & wonderful & useful a block of Nature's mountain handiwork.
There is now under consideration, as doubtless you well know, an application of San Francisco Supervisors for the use of Hetch Hetchy Valley & Lake Eleanor as storage reservoirs for a City water supply. This application should I think be denied, especially the Hetch Hetchy part, for this Valley, as you will see by the inclosed discription, is a counterpart of Yosemite, & one of the most sublime & beautiful & important features of the Park, & to dam & submerge it would be hardly less destructive & deplorable in its effects on the Park in general than would be the damming of Yosemite itself.”
