excellent in this region, and a quantity of material was secured, 
although no one was allowed to go more than thirty yards inland from 
the water's edge. 
From Bahia Honda the Iowans went to Key West, where they were 
not allowed to land on account of a yellow fever scare, but were or- 
dered to quarantine at the Dry Tortugas, which was anything but a 
hardship, for a better ground for marine biological work would be hard 
to find. The quarantine officer, Dr. Robert Murry, was untiring in 
his courtesies, letting the members of the expedition have the full run 
of old Fort Jefferson, and, better yet, of the moat around it, which is, 
in effect, a grand aquarium such as delights the zoological heart. 
On two occasions the whole party had the rare privilege of studying 
fully expanded Millipores, while living corals of many species were 
always at hand. 
Two weeks were spent in dredging on the famous “Pourtales Plateau,” 
between Sand and Sombrero Keys, at depths varying from seventy-five 
to two hundred and fifty fathoms. A great quantity of material was 
thus secured, including some characteristic deep-sea forms, such as 
Asthenosoma, calcareous sponges and old-fashioned corals. 
. Returning again to the Bahamas, the littoral and terrestrial faunas 
near Spanish Wells, Eleuthera, were very carefully explored, and a 
rich harvest seeured. "The shoal conneeting Eleuthera with Little San 
Salvador was dredged, the most notable results being some particularly 
beautiful hydroids. 
Thence a homeward passage of eight days concluded a cruise which 
will be remembered with delight by every member of the party, and 
which was as remarkable for the absence of any mishaps as for the 
educational and scientific results which will certainly accrue. 
In addition to the specimens secured and notes taken by the party, 
a splendid series of photographs, taken principally by Instructor G. L. 
Howser, constitute the best of records of the cruise.
