Cozumel with three members of the field party, Daiber, Hr hder, and 
Schmitt. The others, Bousfield and Clarke, had to return hone on 
April 2k because of other commitments 
Five weeks and a day marked the actual epan of this Yucatan 
expedition from the time we quit the restless, open roadstead of 
Progreso on March 2 6 until we left Mexican waters on April 30 for 
Georgetown, Cayman Islands. There, after a 7k -hour passage, we parted 
company with our chartered 70 -foot auxiliary schooner on May 6, to 
return to Washington . 
In Progreso the purchase of supplies beyond those obtained in Miami, 
and an additional and heavier anchor that the winds here warned ue 
night be needed, left only very limited time for collecting. This was 
chiefly accomplished by Prs, Clarke and Daiber in and about the nearby 
lagoon and mangrove swamp. Some shells were picked up by Dr. Rehder, 
who scoured the beaches . At Iela Mujeres , our next port of call, four 
scientifically profitable days were spent, March 28 through 31. The 
reefs, shoals , turtle grass flats, and stands of mangroves were very

reminiscent of the Florida Key area in faunal aspect. Corals, gorgonlans, 
sponges, mo Husks, crustaceans, fish, and algae were gathered in fair 
quantity within the spacious harbor and along the outer reaches of the 
island. We left for San Miguel, island of Cozumel, shortly after sun- 
up April 1 and dropped anchor off the pier there the very same evening 
at half -past six.
