The testimony of the members of the Board obtained great weight because of their unquestioned technical skill and experience and their positions, entirely disconnected from local prejudice and interest. That the Raker Bill will prove of considerable advantage to nearly all, if not to all, other interests of the State of California outside the Bay section affected by the Bill seems to have been clearly established. IV. What will be the operative effects of the Raker Bill on the Yosemite National Park? The total area flooded in the National Park will be 3373 acres. Of these the city owns about 1300 acres. The Government under the Raker Bill will get, by exchange, the difference between 1300 acres and 3142.78 acres, which is 1842.78. The city will take from the Government the difference between 1300 acres and 3373 acres, which is 2072. Hence, the city will trade to the Government as much land as it takes for flooding, lacking 129.22 acres. The forests to be covered by the flooding are in no part of the large redwoods, but are of a size frequently found in a California forest. [Illustration: MR. M. M.

In the early summer the mosquitoes are bad, in the late summer it is too hot.” Colonel Cosby of the Board of Engineers gave this testimony: “Taylor of Colorado—Do you think these roads, provided for in this bill, will make it accessible to a greater number of people?” “Colonel Cosby—I do. At present I think there are practically only two classes of people who use it, people who are unusually wealthy or people who are unusually strong and healthy and are able to make the trip.”
