One of the three sets taken by J. Dewey Soper on Baffin Island looks much like a miniature set of long-billed curlew's eggs. In three of the eggs the ground color is "mignonette green," covered with small spots, more thickly at the larger end, of "bister" and "snuff brown"; the other has a "deep lichen green" ground color and is irregularly blotched near the larger end, finely speckled elsewhere with "bister" and "brownish drab." The measurements of 34 eggs average 33.7 by 24 millimeters; the eggs showing the four extremes measure =36.1= by 23.6, 34.2 by =27.7=, =31.5= by 23.5, and 35 by =22.8= millimeters. _Young._--Mr. Soper's notes on the young are as follows: The first juveniles, about a day old, were seen and collected on July 11. They were exceedingly active, a good example of precocial young. These were ashy below, buffy above, with black markings, and the down over the lower back and rump tipped with small spots of white. This species is much more demonstrative and less artful in the concealment of young than Baird's sandpiper. The adults come within a few feet of the intruder, and by their action advertise much more clearly the position of the young. The parent birds keep up a continual fine twittering cry of alarm, the female louder and more pronounced. The male comes on the scene only at intervals with a mouse-like squeaking note. The young are adepts in the art of concealment, "freezing" flat to the ground with warning notes from the adults. They will lie in this fashion as though dead until actually picked up in the hand. When they realize the game is up they then become wild and frantically struggle to escape. When allowed to do so they will run rapidly away and either hide again or attempt to reach the mother bird, whose frantic cries come from but a few yards away. A young white rump about two-thirds grown and almost on the point of flight was captured on August 1. Others seen a few days later on the shore of Kuksunittuk Bay were capable of short flights. As an experiment, I tried several times to keep individual young alive at my base tent on the Takuirbing River, but they invariably died within about 24 hours regardless of the best care.
