Some attention is directed to important principles that are espe- 

 cially well illustrated in that phylum; relatively little time goes 

 to details of classification. 



Blackboard drawings, chart and models are employed in the 

 lecture. In general, we find that students will follow a black- 

 hoard drawing made before their eyes, with more interest and 

 understanding, in spite of imperfections in execution, than a de- 

 scription illustrated by the most carefully drawn chart. These 

 drawings are diagrammatic and capable of rapid copying by the 

 class, in preference to exact and detailed reproductions. 



Supervised laboratory study follows the lecture for two hours 

 in the morning and again from two o'clock till four in the after- 

 noon ; normally three instructors are kept busy, though more may 

 be called in on special occasions ; as in the examination of plank- 

 ton. The instructor in charge usually stays on an hour or more 

 later with the students who wish aid in studying their material 

 more fully. The laboratory is open at all hours, and it is unusual 

 to find it empty between six in the morning and eleven at night. 

 Special assistance is given on request whenever an instructor can 

 be reached. 



The students who take this work are required to have had at 

 least one year's laboratory work in college biology and to present 

 a recommendation from their college instructor. The class is 

 limited to 55, and in recent years there has always been more than 

 this number of applications. Qualified students from colleges 

 which regularly support the Marine Biological Laboratory are ad- 

 mitted first ; after these are served admission depends on priority 

 of application and on training. The class is drawn mostly from 

 institutions over the eastern half of the United States from 

 Maine to Nebraska and from New Orleans to Minnesota. At 

 least thirty colleges are represented by one or more students each 

 summer. A few apply who present only the minimum require- 

 ment, but over half of the class has been graduated from college. 



Teachers and graduate students are about equal in number 

 among the college graduates. Older people who desire the course 

 as a matter of intellectual curiosity are always present and wel- 

 come. Admission is not knowingly granted to students who use 

 the course as a convenience to work off college conditions.
