LORQUINIA 
Though we have not the technical knowledge of the savants, 
and, therefore, are unable to write learnedly and at great length on 
profound and intricate problems, which only the trained student 
may handle, it is within the power of us all to render great service 
to science by keeping our eyes open and never neglecting oppor- 
tunities for making observations or collecting specimens wherever 
we may go. By so doing, the collector may feel that he is having 
a share in the work of unravehng the mysteries which Nature holds. 
While he is in this way endeavoring to contribute something for 
the advancement of science, he is constantly experiencing new 
surprises, viewing new scenes. 
Is it at all strange that one who has once enjoyed the pleasures 
of collecting should love to go forth into the open fields — Nature's 
workshop — and, in anticipation of some new revelation or view that 
has long remained hidden, never tire, but be lured on and on with 
the hope that he himself may discover the .fields before him^ and 
therefore add his mite to the sum of human knowledge? 
Is it not strange that so many pass by oblivious, without heeding 
the call of Nature, inviting them to take a look, if but for a moment, 
at the monuments she has erected, at the work she has been per- 
forming since time began, or that so many pass from earth without 
realizing that they have missed the best part of the performance 
enacted on the stage of Creation, where all characters are real 
and where there are no shams or make-up ?

SHELL COLLECTING AT SAN PEDRO 
On the afternoon of November 25th, 1916, a very low tide en- 
abled F. Grinnell, Jr., Geo. Malcolm and E. P. Chace to collect shells 
about the Breakwater at San Pedro, California. The Nature Study 
Department of the Los Angeles Schools was also present, about 1000 
children being under the direction of Dr. Charles L. Edwards and his 
assistants. 
Several Nudihranchs were collected by the children. Nudi- 
hranchs, some of which are very beautifully colored, have no shells 
and are called naked molluscs. This group includes those forms 
which are commonly called sea-hares.
