In short every argument for damming H. H. would apply with equal force to damming Yosemite. To say that only the Hetch Hetchy
water is available for San F. water supply is like saying that only the water shed from a single row of shingles is fit to
drink. Mr Phelan is reported as saying that 'H. H. is inaccessible 9 mos. of the year unliveable the other 3 on account of
mosquitoes.' It is accessible all the year is not more mosquitoful at any season than Yosemite Also that 1000s of valleys
as beautiful as H.H. are to be found in the Sierra On the contrary none are to be be found in the park excepting Yosemite
itself, while its location as related to other great features of the park make it supremely important etc etc etc. Ever yours
faithfully John Muir
