as the Grasshopper and Henslow's Sparrows, Bhie-headed Vireo, 

 etc. Prolonged warmth holds some birds here and further north 

 in abunilance greater than is usual. The effect of temperature is 

 illustrated in the Mockingbird. At the beginning of October, 

 18S9, they were abundant, but a sharp turn and heavy frost 

 drove all but winter numbers southward before the week was 

 over. The year before, when exceptionally mild, the}^ had not 

 reached this basis on the 34th, although diminished by a cool 

 wave and slight frost that came September 30. It appears to be 

 true that an early cool spell is more potential with certain species 

 than subsequent protracted mildness — the bulk retiring before 

 the chill instead of tiding it over. The genial weather later, how- 

 ever, may encourage other species coming from further north to 

 remain in larger numbers than they would if it were ordinarily 

 cold.

A PRELIMINARY LIST OF THE BIRDS OF THE 

 GRAY'S HARBOR REGION, WASHINGTON. 



BY R. H. LAWRENCE. 



Gray's Harbor lies on the Pacific Ocean in the extreme 

 western part of Chehalis County, Washington, about fortv miles 

 north of the mouth of the Columbia River. It is the most north- 

 ern of the few safe and large harbors between San Francisco 

 and the Straits of Fuca. The harbor drains a large area, is bor- 

 dered by much marshy land, and, being large and mostly shallow, 

 shows when the tide is low a vast expanse of mud-flats cleanly 

 cut by the two main channels — the north and the south. These 

 channels separate inside the bar and run eastward till they join 

 again near Aberdeen. The harbor is about sixteen miles long 

 east and west, by twelve north and south at its western end, nar- 

 rowing much toward its eastern end. It is protected from the 

 sea by two long, narrow, sandy points, Point Brown on the north 

 and Point Chehalis on the south. Its largest river, the Chehalis, 

 rises in the Cascade Mountains near Mount Rainier, and is navi- 

 gable by steamers for twenty miles or more. The Humptulips,
