cabin there were two long, movable windows. In one corner of the cabin 
there was a well equipped dark room for photographic work. Along one 
side of the room was a laboratory table fitted with drawers and shelves, 
and in another part were numerous shelves for specimen jars and dishes. 
A common cooking stove adorned one corner of the room, and in the floor 
were two large galvanized-iron tanks in which eatables were stored. Be- 
sides a complete cooking outfit, cots and bedding, we had various kinds of 
seines, gill nets, hooks and lines, microscopes, dissecting tools, injecting 
apparatus, and all other things needed for preserving any material that 
we might find. Besides a large number of jars and bottles, two large 
galvanized-iron tanks served for storing preserved material. Formalin 
was used altogether for preserving museum and anatomical material, 
and it worked exceedingly well, except when left in the sun. Under 
the latter conditions, the formalin seemed to decompose and the material 
would spoil. 
We guided our boat, which we named ‘‘Megalops,” by means of two 
large oars that worked in oar locks placed on each end of the boat, and 
we found no difficulty whatever in directing the boat just where we 
wished, except when the wind was blowing. At such times it was fre- 
quently necessary to anchor until the wind ceased. Our speed was seldom 
rapid, but it was usually very satisfactory. We would move a mile or so 
and then probably stop a day or two to investigate the ground, and would 
remain at one place as long as the collecting was profitable. During the 
four months we were out we traveled from Mankato on the Minnesota 
River to Red Wing on the Mississippi, and did not meet with a single acci- 
dent of any consequence. It will be remembered, also, that much of this 
distance is frequented by steamboats, rafts and floating logs. 
At times there were as many as six persons in the party, but usually 
only five. During the four months that the Megalops was in commission, 
the following persons were on her for work: Prof. H. F. Nachtrieb, of the 
State University of Minnesota, and Chief of the Zoological Survey; Dr. 
D. T. McDougal, of the Bronx Park Botanical Gardens, New York City; 
Dr. W. S. Nickerson, of the Minnesota State University Medical School; 
W. S. Kienholtz, J. BE. Guthrie, and Charles Zeleny, students of the Uni- 
versity; George Hinton, the “boy” and “‘cookee,” and the writer, who was 
dubbed the ‘“‘captain.” 
In every way the trip was a success. We discovered a number of
