Nore.—I have several times spoken of the state of the thermometer. 
At all times it was placed beneath the shade of a tree, and hanging 
against it. In no case was it hung in the tent, where the heat was

Colorado, except mine, an aneroid, which I gave to Lieutenant Whipple, 
in order that his records might be kept complete. So with my ther- 
mometer. It was lost, and I was afterwards obliged to refer to Lieute- 
nant Whipple’s. Before leaving Fort Yuma, Dr. J. L. Milhau, surgeon 
of the post, at my request, kindly furnished me with a copy of the me 
teorological register kept at the Fort for the month previous to my de- 
parture, from which I have made the annexed extract:

of bushes, which effectually shut out the sun at all times, while

rock about eighty feet above the plain.
