Description:
The first publication of the Arizona Bureau of Mines on Arizona
Gold Placers was written by Mr. M. A. Allen, when Geologist
with the Bureau, and appeared in 1922 as Bulletin 118. It
was mainly a compilation of data already in print, but scattered
and difficult to find. The stock of this bulletin was exhausted
in four years. Mr. Eldred D. Wilson, Geologist with the Bureau,
was then commissioned to re-write the bulletin, adding what
new data could be obtained. Assisted by Mr. W. R. Hoffman in
the field and further aided by the advice and suggestions of Dr.
Carl Lausen, then Geologist with the Bureau, Mr. Wilson completed
his work in the summer of 1927 and a large edition was
published at once as Bulletin 124. Conditions with which everyone
is familiar developed within two or three years and so much
interest was shown in gold that the demand for this bulletin was
extremely heavy and the supply was exhausted before June of
last year. A new and greatly enlarged bulletin, No. 132, was
prepared at that time, and, although five thousand copies were
printed, they have all been distributed.
The present bulletin does not differ radically from No. 132, but
many parts of that bulletin have been re-written and an attempt
has been made to bring the information obtained therein up to
date. Mr. Eldred D. Wilson made the field investigations required
to secure this new data, and at least a dozen additional
districts are described in the present bulletin. 148 p.
