some of these excursions digging and shallow water collecting was the object. 

 In others, dredges were used in deeper water. On one afternoon the class 

 accepted the invitation from Dr. H. M. Smith of the U. S. Fish Commission, to 

 go on a dredging trip on the Steamer " Fish Hawk" and had the privilege of 

 seeing how dredging is done by means of the most efficient and up-to-date 

 apparatus. 



The course of study covered six weeks, beginning July 3d, and ending 

 August 13th. It consisted in both lectures and laboratory work. The lectures, 

 which were given daily, from 9 to 10 a. m., by the instructors, had for their subject 

 matter the natural history, classification, anatomy and development of the ani- 

 mals or groups of animals to be studied in the laboratory during the day. The 

 instructor who gave the morning lecture had charge of the laboratory work 

 which followed. In this he was assisted by two other instructors. He had

selected the forms for study and was responsible for their collection and prep- 

 aration for the students. He had, with a few exceptions, prepared the labora- 

 tory outlines which were used by the students in their studies and dissections. 

 For a few forms Bumpus' " Invertebrate Zoology '" was used. 



In addition to these elementary lectures by the instructors it was intended 

 that each day's work should close with a lecture by an investigator of the group 

 being studied on some subject in which he is interested relating to the group. 

 This plan was given up for two reasons, the investigators were either not at 

 Wood's Holl or were unwilling to lecture, and at 4 o'clock the greater part of 

 the students wanted to go bathing. Those lectures which had been promised, 

 before the course began, were given — the three by Professor C. O. Whitman
