April 11th,1930.
Dr. Herman Schlundt,
University of Missouri,
Columbia, Mo.
Dear Dr. Schlundt:
I have today wired you giving you results of my
test upon the samples of ore sent from Winnemucca by Mr. Lee.
For fear that the telegram may have been somewhat garbled I repeat
my findings:
Samples 1-X and 1-2 contain approximately 14%
U3O8. Samples 2-A and 2-B contain approximately 12%, while sample
from claim #4 showed 2% only.
There was one rather odd fact
which I found with reference to all of these samples, with the
exception of #4, and that is that during the first few moment that
the samples were in the alpha ray electroscope the rate of the leafe
increased quite materially, but as I stated in my wire I based my
computation upon the maximum value or the most rapid fall of the
leaf.
These samples of ore are quite different in their
physical appearance from the sample that was submitted to us by
Mr. Luber, and while I have not had an opportunity to make a very
extensive study, still I do know that they are very resistant to
chemical treatment. I imagine the processing of this ore for
recovering of the radium might present a rather complicated problem,
and one which would be costly.
I shall await your results with interest to see
whether or not they check my findings. I am running an emanation
determination either tomorrow or Monday, which will give me informa-
tion as to whether or not the alpha ray test on these ores represent
the true radium content. From the nature of the ore I rather feel
that we will not find a condition applying here which I find in the
case of the Luber sample - that is that the radium content was some
5 or 6 times that indicated by the alpha ray examination.
I must apologize for not having sent you the speci-
men of zinc sulphide, but am glad to state that same is going forward
under separate cover today. You will not find this specimen any too
free from alpha radiation, for it has been stored around our place
here as well as the place where it was manufactured, the both of
which are more or less radio-active.
Sincerely yours,
Vice President.
