Norse.—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 
much greater. Our barometers had all been broken before reaching the 
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 there 
was a free circulation of air around. The Fort stands on an isolated 
rock about eighty feet above the plain.
