The Laboratory gives no credit for work done in its courses, 

 nor does it keep formal record books. A student so desiring may 

 receive a certificate stating that the work of the course has been 

 satisfactorily completed and may then cash this in at his college 

 for undergraduate, and in most institutions, for graduate credit 

 (e.g., Chicago, Wisconsin, Cornell). All colleges do not allow 

 the same amount of credit ; the usual practice is to give from 5 to 

 6 semester hours' credit for the work of the course. Any student 

 may have his laboratory notes inspected by the instructor in charge 

 of the group, and all persons asking for certificates must submit 

 their notes for such inspection. 



The course outlined is sufficiently different from the ordinary 

 college course, both in its method of presentation and its effect 

 upon students, to arouse constant curiosity as to its essential points 

 of variation. At Woods Hole there are unusual temptations to 

 sight-seeing, boating and bathing, but the attitude of the class is 

 anything but the summer-vacation type that prevails in many 

 summer schools. 



The great efficiency and speed attained and held by the class 

 through the six weeks must be ascribed in some degree to the 

 presence of three trained teachers, the instructor in charge and the 

 two assisting members of the staff, who are always at hand in the 

 laboratory when needed ; though they give as little oral instruc- 

 tion as possible, so that the student is a more independent worker 

 at th'e end of the course than he was at the beginning. 



I am inclined to think that the intensive work which the 

 students accomplish is clue in part to the very speed with which 

 ground is covered. It appeals to the imagination of the student 

 to look back at the end of ten days over the Protozoa, the sponges 

 and ccelenterates, with three field trips extra. Further, he has 

 the advantage of no other study to distract his mind. Through 

 the winter his attention must ordinarily be stretched over three
