insect-like note. On my descent again into the valley, they 

 were practically left behind after I had passed below the 2,000 

 foot level, A few days later, on September 13th, among the 

 deeper forests of the Carter mountains, they were found to be 

 common in small flocks. "We had noticed a few scattered indi- 

 viduals along the valley road, but on entering the upland woods 

 at about 2,000 feet, they became at once numerous. The fol- 

 lowing day we found them in numbers among the higher forests 

 on Carter Dome and the mountains beyond. They seemed to 

 be merely roving through the trees in loose flocks, or fljang 

 about from one place to another in a restless, aimless way. We 

 camped that evening at the Carter lyakes, and arose early on 

 the morning of the 15th of September after a clear, cold night. 

 The altitude at the lakes is 3,360 feet, and on either side tower 

 the walls of the Carter Notch, a great rift in the mountain with 

 a valley opening out towards the north and another to the south, 

 Shorth^ after the sun had begun to creep down the farther wall 

 of the Notch, there commenced a large flight of Black-poll and 

 Myrtle Warblers, By singles, pairs, threes, or in small flocks 

 of from four to six birds, these warblers came flying in from the 

 south, high in the air, making straight for the Notch, Many, 

 on reaching this point, kept on over the divide to the north- 

 ward. Others wavered at the height of land (3,460 feet) but 

 still kept on till out of sight, while yet others, and these mainly 

 the Myrtle Warblers, turned to alight among the trees on 

 the mountain side, or about the lakes. This flight contin- 

 ued from 4 :30 or 5 o'clock a. m., for over two hours, during 

 which time several hundred birds passed; by actual count. Of 

 these, about one quarter were Myrtle Warblers, the rest Black- 

 polls. By 9 a. m., only an occasional bird or two was observed, 

 and the flight was practically over. It seemed as if the Black- 

 poll Warblers from all the forests immediatel}^ to the south were 

 moving north in a concerted manner to the pass through the 

 Notch and off bej^ond. Possibly they were heading for the Am- 

 monoosuc Valley to continue thence down the Connecticut ; this 

 would ])e a natural course, and one cannot suppose that their 

 northward flight at this season could have been more than some 

 such local movement.
