August 4, 1924, Monday. Ibis brought and took mail. 
Tried crab nets over last night in Fort Jefferson moat, from entrance 
gangway. Got no crabs thusly, but from some bunches of seaweed from near 
intake pipe on S.E. side got several shrimps. 
Soft grapsoid from around base of pile where it had rotted away from 
concrete footing. 
Went dredging with Mills net off N.W. end (N.W. of lighthouse) of 
Loggerhead Key, about 3/4 to 1 mile off in average 10 feet of water; mostly 
eel grass bottom, some sand areas and, judging from hauls (made four or 
five hauls) broken coral fragments, 6-8 inches, many 1-2, all dead and much 
overgrown with lots of brown eel grass and many roots. Some hauls were made 
in as little as 5 feet, much same character bottom. 
Charley got a Calappa in the moat, live, buried in sand. With chelipeds 
a little away from body kicks out with hind legs backward, pushes chelipeds 
away from the body, repeats,and so works way down in sand.
