50 IOWA STUDIES IN NATURAL HISTORY 
north; and on the other side of this wall is the building which we 
occupied as a laboratory. It is a large wooden structure, 80 by 
30 feet, and like the men’s quarters has an elevated porch run- 
ning the full length of each side. It is near the landing at the 
north and convenient to the water on both sides. There are 
numerous windows with heavy wooden shutters conveniently 
spaced along the side walls; and two doors, one on either side. 
There were a number of small but solid tables, one for each 
worker, opposite windows. Our alcohol tanks formed conven- 
ient seats for all. Other tables along the center of the room were 
used for glassware, reagents, etc.; while two cupboards with 
doors contained stationery and some general laboratory sup- 
plies. In the north end of this main room Dr. Job installed his 
aquaria, surmounted at the top by a large barrel, into which 
water was supplied by Eustace, our boy of all work, who dipped 
the water from along the sea wall a few paces away. From this 
barrel, rubber tubing led to the various glass vessels constitut- 
ing the aquaria, which were on a series of step-like shelves made 
from some of the boxes which had been used as containers for 
our equipment. We met with a great deal of difficulty in main- 
taining just the right flow for these vessels, but succeeded in 
keeping a good many specimens alive for a reasonable time or 
at least until we were ready to kill them for future use. 
The supply of fibre buckets and tubs which we had brought 
along was immensely useful, indeed indispensable. They were 
light, durable, and never came to pieces or leaked. They were 
uninjured during the season’s work, and many of them were re- 
turned for future use at the University. 
The north end of the building was separated from the main 
laboratory by a partition. Here was installed our ‘‘lbrary,”’ 
and also a place devoted to Ricker, where he photographed liy- 
ing specimens brought in by the collectors. 
A number of shower-baths were contained in separate build- 
ings near the laboratory, and these were exceedingly useful in 
killing and cleaning corals, many fine specimens of which were 
collected from the reefs quite near Pelican Island. At the 
extreme north is a sand-beach, which was used as a bathing 
place, principally by the ladies of the party, and was prac- 
tically devoid of the black sea-urchins, or ‘‘sea-egg;’’ which is
