Ii is clear. therefore, that the stones
must have reached their late resting
places in the drift through the agency
of the ice mantle, and we should, there
fore, study the direction of glacial
movements throughout the region to
discover the law of their distribution.
and to CLEAN any facts that may be
within our reach regarding the ances-
trail homes which they occupied before
they were carried away by the ice.
The problem of locating the area from
which the diamonds of the drift have
been derived is a fascinating one, and,
while the data now available are in
sufficient for its complete solution, they
are of kind to indicate that, with the
increase of our knowledge likely to
come in the next decade, the desired
end may yet be reached.
The first question which naturally
arises is whether all the diamonds that
have been found in the lake region
have been derived from a common
source. While there Is no certain evil
dence that they have, nevertheless it
would seem to be probable. Diamond
bearing rocks are not SO numerous that
there is much likelihood of two uncon-
nected areas being discovered in the
region in question. Moreover, the &C.
currence of diamonds with somewhat
similar crystal habits over SO large a
territory would seem to be significant.
Before the home of the diamonds can
be located with definiteness, It will be
necessary to carry out several lines OF
investigation. OF first Importance is 1t
that the direction of ice movement be
studied in as much detail as possible in
the territory surrounding Hudson Bay
on the southwest south and east. 1t
will be important also to search the NOR
aines south of the lakes, and particular
ly the marginal ones, for diamonds,
since the evidence points to them as
the principal repository of the emigrat-
ed stones 1t Is especially important to
examine the moraines of Ohio, western
New York and western Pennsylvania
in order to determine whether the fan
of distribution extends farther in that
direction If this is true, the apex of
the fan would seem to be located very
near to the center of the Labradorean
neve.
1t has seemed to the writer that much
might be gained by arousing an inter-
est in the problem in the people who
reside on or near the moraines, and
suggesting to them that children par
ticularly be urged to use their keen
eyes in search for the diamonds that
have been sown in the drift.
For the encouragement of these dia-
mond seekers it is as well to enumer-
ate the discoveries made on this con-
tinent of valuable diamonds. The writ
ers interest having been aroused in the
reported finding of stones, he investi-
gated and after some correspondence
learned that a yellow diamond of over
Is carats' weight was in the possession
of Col S. S. Boynton. jeweler of Chi
