436 A. E. Verrill—Results of recent Dredging Eapeditions 
The fishes and the investigations more immediately connected 
with the fisheries were attended to by Prof. Baird, aided by his _ 
secretary, Mr. Rockwell, Prof. Theodore Gill, Dr. Edw. Palmer, 
Mr. G. Brown Goode, Mr. Spencer Biddle and others. The 
dredging operations, the examination of the food of fishes, and 
all investigations concerning the invertebrate animals generally, 
were in charge of the writer an r. S. I. Smith, aided by 
Prof. Wm. N. Rice and Mr. Goode, of Wesleyan University ; 
Prof. J. E. Todd, of Tabor College, lowa; Prof. H. E. Nelson, of 
Ohio Wesleyan University ; Mr. J. H. Emerton, Salem, Mass. ; 
Mr. J. K. Thacher, of Yale College; Mr. Franklin Benner, | 
Astoria, N. Y.; and for a short time by Dr. P. P. Carpenter, of 
Montreal; Dr. Holder, of New York, and several others. 
Much of the success of the expedition was due to the interest 
taken in such scientific researches by Secretary Robeson, who 
caused a small U. S. steamer, the “ Blue-light,” to be specially 
fitted out for our dredging operations, under Commander L. ©: 
Beardsley, U.S. N. This steamer was provided with a steam 
windlass for hoisting the dredges and trawls, and with other 
conveniences, which greatly facilitated our operations, and en- 
abled us to make much longer excursions to the outer waters, 
and to.do much more work during the summer, than would 
otherwise have been possible. Captain Beardsley took great 
interest in our investigations and did all in his power to aid us 
in various ways. is constant endeavor was to make the 
steamer as useful as possible to us. Our thanks are also due to 
Mr. Cook, the executive officer, and to all the other officers and 
men for the hearty good-will with which they codperated in 
our work and executed all our plans. 
Ample wharf privileges were found at “Trefethen’s Land- 
ing a large assortment of dredges, rake-dredges, tangles, traw ®) 
towing-nets, seines, sieves of various kinds, and all other 
is ment and the dredges, tangles, trawls, rakes, and other PF 
tus used by us, were described and illustrated in several letters to * eats ty 
together in the “ Tribune Extra,” No. 10, Scientific Series.
