MUSEUM OF COMPARATIVE ZOOLOGY. 21 
is proposed to introduce in the laboratory studies. The field work 
in this course will include studies of localities of Cambrian and 
Carboniferous rocks within half a day’s journey of Boston, de- 
signed to illustrate these periods, and at the same time afford 
training in methods of field work. 
In connection with the field work of Course 8 Professor 
Woodworth continued his search in Plainville and Attleboro 
for the interesting foot-prints believed to be mainly Amphibian 
in the Carboniferous shales of the Narragansett area. Several 
_ new forms or varieties have been found and sufficient material is 
in hand to warrant the publication of a second paper on these 
tracks. In the April recess a week was spent on Martha’s 
Vineyard in collecting rocks and fossils for the Geological 
Museum and for the Laboratory. Worthy of a place in the 


Museum are several examples of sand-blasted pebbles from 
Katama, and a large variety of rocks from Gay Head, including 
aetites, fossiliferous Potsdam pebbles, the greensand from the 
_ Miocene beds, and Cretaceous sands and clays. Mr. Starratt 
assisted in the collecting of this material and in obtaining 
some lignite for Professor Jeffrey of the Botanical Museum. 
The Laboratory received from Mr. Philip T. Coolidge, of 
Watertown, Mass., the valuable gift of a series of rocks and 
fossils collected by him in eastern New York during the session of 
thesummer school of 1903. The following gifts are also gratefully 
acknowledged: from Dr. James M. Bell, specimens of the glacial 
clays and interglacial lignites of northern and northwestern 
Ontario; from Professor Penck, sand-blasted fragments of lime- 
stone from the mouth of the Virgen River, Arizona; from Mr. 
_W. T. Harrison, fragments of fossils from the Middle Cambrian 
of Braintree, Mass.; from Mr. Albert P. Morse, a collection of 
sand-blasted wood from the dunes of Ipswich, Mass. This last 
collection has been reserved for the Geological Museum. The 
teaching material has also been increased by the making of over 
a hundred negatives of published illustrations from which en- 
larged photographic diagrams will be made next year. Professor 
Woodworth made a collection of rocks and fossils from the Crazy 
Mountains, the Gallatin Cafion, and Old Baldy Mountain, in 
Montana, for the Laboratory, in the course of the Western Sum- 
mer School. | 
Professor Woodworth continued to devote considerable time to 
the New York Geological Survey. In September of last year a
