TEACHERS' SCHOOL OF SCIENCE. 651 



that course to be a necessary foundation for further botanical 

 study. 



Another feature of The Teachers' School of Science should not 

 remain unnoticed. It consists of effective work in zoology and 

 geology by Mr. A. W. Grabau, the official guide in the museum 

 and a graduate student of geology. A course of lessons on The 

 Shore Animals of New England was begun by him in April, 1897. 

 Directly connected with these field lessons was held a class in labo- 

 ratory work, which was attended by about twenty persons. 



The next year Mr. Grabau endeavored to give his audience a 

 comprehensive view of the action of cold and heat, of winds and 

 waves, rain and rivers, and of the chemical effect of the atmosphere 

 in the production of the natural features of the earth's surface, by 

 giving eight lectures on The Surface of the Earth, its Rocks, Soils, 

 and Scenery. Special attention was given to the scenery of New 

 England, and this awakened an interest in local scenery, which in- 

 terest led to Mr. Grabau giving several lectures in surrounding 

 towns, under local auspices. One of these lectures called the atten- 

 tion of the people of Arlington, Massachusetts, to the fact that they 

 had in their midst a valuable geological monument, and led them 

 to start a movement for the preservation of a terminal bowlder 

 moraine on Arlington Heights, which is the only good accessible 

 example of such moraine near Boston. 



Under the same instruction ten lessons were given on the use 

 of the microscope and the preparation of specimens of hydroids. 



The work begun at the winter lectures was continued during the 

 spring by excursions to the seashore. The beaches of Revere, 

 Swampscott, Marblehead; the cliffs and tide pools of Nahant, Mar- 

 blehead Neck, and Nantasket, and the mud flats and piles of Bev- 

 erly, were explored. One excursion was made to the outer shore 

 of Cape Cod and Buzzards Bay. The party spent four days on 

 this excursion. 



During the early part of the summer an outing was made to 

 Bayville, Maine, where a laboratory was furnished, with microscopes 

 and other accessories, and fourteen persons (mostly teachers) de- 

 voted ten days to the study of marine fauna, special attention being 

 given to hydroids. Some geology was studied during this excur- 

 sion, and a small island mapped. Those who attended this expedi- 

 tion were delighted with an experience new to most of them, as 

 many of them had not before studied zoology and knew not what 

 a field could be opened by the study of natural history. One of 

 the party afterward remarked, " I feel as if I had been born into a 

 new world, so different are these things in their homes from their 

 representations in books."
