Fig. 2. View of some tidal ponds. 
with an aggregate capacity of 20,000 gallons. 
The aquaria and tanks are provided with cir- 
culating sea water by a pumping plant separ- 
ate from that which supplies the system in 
the laboratory building. 
Laboratory and auxiliary buildings: The la- 
boratory building (Figs. 3, 4) faces southeast 
and borders a large dredged lagoon. The 
dock is connected to the laboratory structure 
with a concrete lanai, thus facilitating the 
transfer of living specimens from the live 
well of the laboratory’s research vessel, the 
Salpa, to the aquarium tables of the labor- 
atory just 30 feet away. Collecting gear and 
supplies may also be transferred readily to 
and from the Salpa. 
The building contains two large laborato- 
ries, one for general biological work and one 
for physiological research, and two smaller 
general-purpose laboratories (Fig. 5). Fluores- 
cent overhead lights assure adequate illu- 
mination. Four to six investigators may be 
conveniently located in each of the larger 
laboratories and two in each of the smaller 
laboratories. In addition to the laboratories 
there are a work shop, a darkroom, three store- 
rooms, a collection room, and a long con- 
crete lanai on which the aquarium tables are 
located, thus keeping the sea water out of the 
laboratories proper. The remainder of the 
laboratory building consists of living quar- 
ters with two large bedrooms, one large dor- 
mitory, a kitchen, a combination dining and 
living room, and bathrooms. 
Additional living quarters are located in a 
second building. These consist of two large 
bedrooms, one smaller bedroom, bathroom, 
and living quarters for the caretaker. An 
electrically operated marine railway which 
can handle all the smaller craft, and a large 
storage house for pond screens and other 
large equipment, complete the present plant. 
Laboratory equipment: Running sea water 
with a salinity of about 35 to 36 parts per 
thousand is distributed to both the large out- 
door aquaria and to the smaller salt-water
