REPORT OF COMMISSIONER OF FISH AND FISHERIES. 89 



WOODS HOLE LABORATORY. 



The Woods Hole laboratory of the Commission was opened as usual 

 during the summer of 1894 for the prosecution of scientific researches 

 bearing- upon the marine animals and plants of the regiou, and advan- 

 tage was taken of the excellent facilities there afforded for that purpose 

 by twenty-three investigators, representing thirteen prominent educa- 

 tional, institutions. Several of these workers arrived during the latter 

 half of June, but the greater number were present during July and 

 August only, a few, however, remaining into September. Less work 

 was undertaken here this year than last in the direct interest of the 

 Commission, as its scientific assistants, both permanent and temporary, 

 were mostly employed in other phxces. 



The Commissioner made Woods Hole his headquarters during the 

 greater i^art of the summer, and, as usual, gave much of his time to 

 the scientific problems which were in course of study, aiding and pro- 

 moting the inquiries by suggestion and by active participation in cer- 

 tain branches of the work. As in 1893, Mr. J. Percy Moore, instructor 

 in biology in the University of Pennsylvania, was in charge of the 

 laboratory, reaching there on June 4 and remaining until September 

 14. The other naturalists in attendance were the .following: Prof. 

 P. H. Herrick, of Adelbert College; Dr. James I. Peck and Mr. N. R. 

 Harrington, of Williams College; Dr. William Patten, Mr. W. A. Red- 

 inbaugh, and Mr. Herbert Tetlow, of Dartmouth College; Mr. F. S. 

 Conant, Mr. H. McE. Knower, and Mr. George Lefevre, of Johns Hop- 

 kins University; Dr. Charles McClure and Mr. Ulric Dahlgren, of 

 Princeton College ; Dr. Jacques Loeb, of the University of Chicago ; Dr. 

 Ira van Gieson, of Columbia University; Mr. W. E. Castle, of Harvard 

 University; Dr. W. S. Nickerson, of the University of Colorado; Dr. 

 John A. Ryder and Mr. Philip P. Calvert, of the University of Penn- 

 sylvania; Mr. Maurice A. Bigelow and Mr. Edgar A. Bedford, of the 

 Ohio Wesleyan University; Mr. Warren H. Everett, of Hamilton Col- 

 lege; Mr. Howard A. Ross and Mr. William Frye White, of Bowdoiu 

 College; Dr. W. E. Wolhaupter, of the Fish Commission. 



It was hoped that the opportunity would be afforded for the study of 

 the embryology of the mackerel by Mr. Moore, but unfortunately the 

 circumstances did not jjermit. During June he cooperated with Mr. 

 Viual N. Edwards and Dr. W. E. Wolhaupter, who were engaged in 

 making observations respecting the habits of the mackerel and the 

 mackerel fisheries in the important breeding regiou along the southern 

 coast of New England, but the practical failure of the fishermen to 

 obtain fares at the proper season made it ini])ossible for him to secure 

 the material required for his special researches. 



During the remainder of the season Mr. Moore was chiefly occupied, 

 under the direction of the Commissioner, in reorganizing the tyjie 

 collection of local marine animals, being assisted at difierent times 

 by Messrs. Bedford, Ross, and AVhitc. This collection has gradually
