BARBADOS-ANTIGUA EXPEDITION 21 
the pump, the finer sand and mud is washed away and the 
smaller mollusks can be picked out, while the remainder of the 
sand is placed in canvas bags to be picked over carefully after 
it is dry. In this way many minute mollusks and Foraminifera, 
ete. are saved; and these often prove to be of greater interest 
than the larger things. 
Tangles such as described in the narrative of the Bahama 
Expedition, but smaller on account of the comparatively small 
size of the boat used, were also employed They are particularly 
available when the bottom is rocky, in which case the employ- 
ment of the dredge is impracticable. Some good hauls were 
made by the use of these tangles; but it may be said that on 
this cruise the dredge gave better results, perhaps owing to the 
skill in its use which long practice had given Mr. Henderson 
and Captain Greenlaw. In regard to the latter, it is but just 
to say that he is by far the most expert man in the management 
of such a launch and equipment that I have ever seen. He 
could go out by himself and do the whole thing unaided and 
most successfully, managing the launch and dredge with the 
most consummate skill. Moreover, he kept his head in ease of 
sudden emergency in a manner that evoked the admiration of 
our entire party. He was absolute master of his engine and a 
wizard in making it behave itself under all circumstances. 
The Committee on Care of Collections had for its duties the 
kind and quantities of the various containers that would be 
needed, the preservatives to be used, labels of various sorts, and 
instruments for collecting aside from the dredging equipment. 
Twenty-four ten-gallon galvanized iron tanks with screw tops, 
placed in solidly constructed wooden boxes with iron handles 
were prepared for the bulkier ‘‘wet’’ material to be kept in 
alcohol or formalin. On the outward voyage these were exceed- 
ingly useful for carrying a good deal of our equipment, instru- 
ments, ete. Besides these we took four chests devised by Dr. Paul 
Bartsch of the United States National Museum. These were 
strongly built with two tiers of square bottles fitting into cor- 
rugated pasteboard compartments similar to those used in trans- 
porting eggs. Each box contained one hundred eight of these 
square bottles, somewhat over five inches high, and the whole 
arrangement worked admirably, hardly a bottle being broken.
