of young every season, and without doubt they would have continued to resort 

 to Great Meadow for an indefinite period, had not the reservoir been abandoned, 

 ' and its waters almost completely drained, in the autumn of 1901 ; since then the 

 birds have ceased, of course, to frequent the place. 



The locality just mentioned is the only one in the Cambridge Region where 

 the Pied-billed Grebe is known to have been found breeding ; everywhere else it 

 is of rare occurrence in spring, but in September and October migrating birds 

 alight rather frequently in most of our ponds, preferring those which have shal- 

 low, weed-grown coves, and sometimes lingering for weeks at a time if not too 

 much disturbed by the gunners. They also used to frequent the reaches of 

 Charles River lying between the Cambridge Cemetery and the Watertown 

 Arsenal, and they have been seen there occasionally within the, past few years.

 1869, and November 23, 1870, while on May 5 and 6, 1879, I observed two 

 birds, no doubt a pair, swimming together off Hemlock Point. Mr. O. A. 

 Lothrop tells me that one appeared in this pond on October 21, 1899, remain- 

 ing until the 26th. Another, which was seen there almost daily from November 

 19 to December i, 1902, became so tame that several of my friends approached 

 it within a few yards as it was fishing close to shore. Unfortunately it was not 

 content to spend its entire time in this sheet of water, but established a habit of 

 flying to a flooded clay-pit in the eastern part of Belmont where it was shot, late 

 in the afternoon of December i, by Thomas Mahoney, a young sportsman, who 

 brought the bird to me that same evening. The two instances last mentioned
