576 BULLETIN OF THE BUREAU OP FISHERIES. 



bait slowly and a fly not at all. On September 23 the writer, in the pool below the 

 sluice, caught about a dozen trout 7 to 12 inches long. They were nearly or quite in 

 breeding condition and rather dark colored and slab-sided. On the 24th six trout from 

 6 to 10 inches long were taken on the fly. The smallest was an immature female, the 

 others well-advanced males. Just above the dam one plump but white-meated trout 

 was secured. Notwithstanding the much higher water, no trout could be caught up 

 the stream where they were caught in July. 



Swift Cambridge.— This stream is said to have once afforded excellent trout fishing 

 and to be still a good trout stream in the spring and early summer at certain places in 

 its course. On July 11, 1905, the writer caught six trout from 5 to 8J^ inches long in 

 the rocky pools below the Andover road bridge. 



Sturtevants Brook. — During the summer of 1905 scarcely any water entered the lake 

 from this brook. It was but a trickling rivulet, although the water was cold. On August 

 9 three trout were caught in shallow water at the mouth. One taken on a fly weighed 

 2>2 pounds. Two others of one-half and i pound, respectively, were taken on worm 

 bait. Again, on August 12, one of one-half pound was caught here on worm bait. It 

 was reported, however, that Mr. Button had made some good catches on a fly at this 

 place. 



Not far from this brook is the famous deep hole of Umbagog Lake, off the mouth 

 of Sunday Cove. In about 53 feet of water, on August 1 2 , one trout weighing i pound was 

 caught on worm bait, and on August 17 six trout from about 10 to 12 inches in length 

 were taken in a gill net set in the same place. With the trout, six salmon and one white- 

 fish were caught. One of the salmon's stomach contained three smelts. 



Molnichwock Pond. — ^This pond once afforded comparatively large trout. Fishing 

 through the ice in the latter part of the winter of 18S3, the writer caught two trout of 

 about 2 pounds each, and on August 18, 1905, he caught here six trout, three of which 

 were 8, 8X1 and 8^ (one being a well-advanced female), and three were i2j^, 13, and 

 13 inches long, respectively. All of the latter were well-advanced females. The i2yi- 

 inch fish contained in its stomach a chub miimow {Couesius plumbeus) 4X inches long. 

 The temperature of the outlet of the pond was 56° F., at mouth of inlet 62° F., surface 

 out in the pond 70° F., and the bottom in lo feet of water at the east end of the pond 

 62° F. 



Molnichwock Brook. — At the meadows this brook has for years furnished most 

 excellent brook-trout fishing. If it were not almost impossible to fish the brook in the 

 wooded or alder portion, it would undoubtedly have been exhausted long ago. The 

 writer, on several occasions in 1905, fished this portion of the brook with the following 

 results: July 16, 51 trout, averaging about 8 inches in length, one of three-fourths of a 

 pound; July 27, 55 trout, 7 to 10 inches in length; August 6, 57 trout, 6 to 1 1 inches long. 

 Most of these were secured in the alder tangle below the meadow. On August 23 only 

 3 trout were caught, and they were small, dark-colored individuals, 5 to 6 inches in length. 



SMELT (Osmerus mordax). 



The smelt is most widely known as a marine fish which ascends fresh water to 

 spawn, but there are many coastwise and some rather remote fresh waters that contain 

 smelts as permanent residents. They are the so-called landlocked forms. In some of 

 these fresh waters the smelt attains maturity and breeds when only iX or 2 inches
