Pond Reservation at Hazlewood, Middlesex Fells, Arlington, and 
Stony Brook. 
The lessons for the present spring began on April 23d with an 
attendance of 51. About 70 have enrolled as members of the 
class. These lessons will deal particularly with the mosses, ferns, 
and related plants. Other topics will be treated as occasion offers. 
Zoology This course in charge of Mr. Albert P. Morse, Curator 
of the zoological museum, Wellesley college, had during the spring 
an average attendance of 26. The largest number attending at 
one time was 43, the smallest 7. During the autumn the average 
attendance was 17.2, the largest number being 23, the smallest 14. 
The spring lessons included outdoor observation of the animals 
studied during the winter, insects, bird-life including changes of 
plumage (76 species being observed), tracks of animals, and a 
special lesson on spiders which was kindly contributed by Mr. J. II. 
Emerton. 
The localities visited were chiefly in the city parks and the Metro¬ 
politan Reservations near at hand, but two for special purposes were 
at a greater distance, Cohasset and Ipswich. 
In the autumn lessons the topic of protection, including special 
protective devices and coloration in relation to backgrounds, direc¬ 
tion of light, enemies, and friends, was studied in the field and 
museum with the aid of demonstrations. This subject proved of 
great interest to the class. The localities visited were included 
mostly in the parks and reservations ; two lessons, owing to the 
highly inclement weather, were given in the Museum of compara¬ 
tive zoology at Cambridge. 
The lessons for the present course began on April 23d with an
