CARNEGIE INSTITUTION OF WASHINGTON DIVISION OF PLANT BIOLOGY August 6, 1935. P. O. ADDRESS: ^^ STANFORD UNIVERSITY CALIFORNIA ^ vX-- Dr. C. E^Tt Merriam Lagxmitae California Dear Dr. Merriam: Many thanks for ^rour kind letter of July 30, speaking of my pamphlet on "Dating Pueblo Bonito." There is no one that I would rather get a letter from on such a subject than yourself. When I first went to Flagstaff in 13911, I stayed with D.M. Riordian for a month. It was not so very long after you had been there, and he told me many of the things you had observed in that vicinity. There is (especially one fact I seem to have associated with ^lyou, which I think was told me at that time, namely j|the different altitudes of life zones of the east 'and west sides of the San Francisco mountains. That became an important point in understanding tree growth in different parts of the forest. I am now writing up the climatic features of tree rings and especialltj the cycles which they display in successive years of growth. With very best regards, Sincerely yours. A. E.
