in any feasible way. Klauber is amateur
herpetologist, a good friend and scientific
protege of Dr. VanDenburgh before the latter's death.
His published list of San Diego County
snakes is very creditable. Klauber took me out
to the Scripps Institution beyond Lajolla in the
afternoon yesterday; there we saw Dr. F.B. Sumner
and the latter's "murarium." The chief things
Dr. F.B. Sumner is breeding are the Alabama
races of Peromyscus, a white one in San Jose
Island
[unknown 4], a dark one in the interior of the state,
and one of intermediate tone on the mainland
seashore. Dr. Sumner caught alive and brought
with very few fatalities over 150 of these mice
to Lajolla, where they are thriving and
breeding in his mouse-house. I saw the
first generation from the sand-white race,
bred in confinement, and they are just like
their parents - no darkening. Dr. Sumner
has cross-mated some of the mice, and has
blended intermediate offspring, between parents
of the different races; in other words the
characters do not sharply segregate. So
far, attempted matings between the Alabama
(P. leucopus, ssp.) with Californian P.
maniculatus
, ssp., have proven fruitless. The
Austrian zoologist, Dr. Paul Kammerer, had been at
Lajolla in the forenoon; Dr. Sumner was very

Unknown3 is murarium which is a place where you breed mice and rats under controlled conditions. Thanks for Xref Sara.

Unknown 5 resolved: it is definitely "ssp" which means subspecies.
