Fort Huachuca,Arizona. 
April 26,1907. 
Major E.A.Mearns, 
Surgeon U.S.Army. 
My Dear Major Mearns:- 
In reading your very excellent report on the "Mammals of the 
Mexican Boundry of the United States" several references to the 
elevation of certain points in the Huachuca Mountains are found. 
As there are no lecal records of the elevations in this region, 
and as a recent determination of the banch mark at the post lowered 
it by about two hunderd feet I am taking the liberty of addressing 
you to learn what bench mark was used in the determinations given 
in your paper. 
I have been unable to identify "North Peak" given on page 13, 
but presume it is either Millers Peak of Carres Peak. The former is 
on the north side of Miller’s canon and the latter forms the south 
wakk of the canon. 
I will be greatly obliged to you for any information that 
will clear up these points for me. 
Yours very truly.
