LORQUINIA 
The October number of The American Museum Journal is espe- 
cially good. The article by William K. Gregory on 'The Evolution 
of the Human Race" will interest everyone. Botanists and photo- 
graphers will be interested in an article on the Giant Manzanitas of 
Clear Lake. 
Among the month's additions to the I<orquin Club library is 
No. 1, Vol. I, of the Aquatic World, published by August M. Roth, 
and edited by S. Chichester Lloyd, of Baltimore, Md. It contains 
several well written articles and is nicely gotten out. Anyone in- 
terested in fish-keeping or aquaria will find this well worth look- 
ing up. 
These are only a few of the many good things in the Club 
library. Get in touch with our librarian, Mr. May, and see what he 
has in your special line of study. 
AN OBSERVATION ON THE CLARKE NUTCRACKER 
On August 3L 1917, Charles F. Richter and the whiter observed 
this interesting bird at the north base of Mt. Islip, San Gabriel 
Mountains. On a sloping tableland there is a dense matted growth 
of Chinquapin, Manzanita, Chrysothamniis, Ceanothus cordulatus. For 
tered everywhere and here were a number of the Clarke Nutcracker 
some time we had noticed the opened burs of the Chinquapin scat- 
(Nucifraga columbiana, Wilson) busily getting the burs, which they 
usually carried to a pine tree before they opened them, extracted the 
seeds and dropped the empty husks to the ground. This bird is large 
and showy, so that it seemed to be the commonest avian inhabitant 
of this table land.
