Eggs, known from only one specimen collected in the vicinity of Fort 

 Conger by General Greely, and described as " light pea-green, closely spotted 

 with brown in small specks about the size of a pinhead," 1-10 x 1-00 (see 

 Merriam, Auk, ii, 1885, p. 313). 



Knots feed along the beaches on the small crustaceans and mol- 

 lusca brought in by the waves, and they also frequent muddy places, 

 where, like the true Snipe, they probe the ground for food. They 

 decoy with ease, " bunching " so closely as they wheel into the stools 

 that the entire flock is sometimes killed by a single discharge. Mr. 

 George H. Mackay, in one of his careful and detailed studies of our 

 Shore Birds, describes their notes as a soft umh-qvoit and a little honk. 

 The first is particularly noticeable when flocks are coming to the de- 

 coys (see Auk, x, 1893, pp. 25-35).
