four very uniformly marked eggs, in- 

 cubated about one week. 



No. 3, Date, June 2, 1909; At the 

 edge of a woods, in dense fern and 

 briars; at the north slope of a little 

 knoll caused by a windfall. The nest 

 was placed, at the foot of a tiny fir, 

 directly on the ground. It was com- 

 posed of dry leaves, bindweed stems, 

 shreds of bark and grass, lined with 

 white, dry grass blades, a very typi- 

 cal nest of this specie, except that it 

 was on the ground. It contained five 

 partly incubated eggs, June 13th the 

 young hatched and June 28th the 

 young accompanied the parents in 

 the brush close to the nest. 



No. 4, Date, June 5, 1909; In brushy 

 land with thinly scattered large fir 

 trees; built in the dense top of a 

 scrubby little fir five feet above the 

 ground, saddled on and twined among 

 the numerous small twigs of the fir; 

 composed of bark strips, weedstems 

 and grasses, lined with fine black 

 rootlets and a few feathers. It con- 

 tained four slightly incubated eggs. 



No. 5, Date, May 29, 1910; In a 

 brushy pasture with scattered patches 

 of brush, among the cleared fields; 

 located in a little scrub oak, forty- 

 two inches above the ground, saddled 

 in three horizontal twigs against the 

 trunk; composed of dry weedstems, 

 oak leaves, twigs and some caterpil- 

 lar's silk, lined with rootlets and some 

 hair. It contained five small nestlings, 

 the place was visited again on June 

 12, when approached the young flew 

 out of the nest and hung on to the 

 bushes and limbs nearby. This is 

 the earliest nesting record I have. 



No. 6, Date, June 11, 1911; Along a 

 hillside thickly overgrown with hazel, 

 poison oak and small firs; built four- 

 teen inches above the ground in the 

 branches of a buckbrush tangle, it 

 was partly saddled, partly suspended 

 among the branches, composed of 



grasses, barkstrips and various weed 

 stalks, lined with a number of smaller 

 feathers, some hair, but chiefly round 

 white grasses. It contained six very 

 finely marked eggs which were ap- 

 parently far incubated. June 21, this 

 was occupied by five young and one 

 infertile egg. 



No. 7, Date, June 14, 1911; Aspen 

 woods with dense sallal growth; nest 

 built in sallal bushes at 9 inches ele- 

 vation, very frail, loose nest; entirely 

 composed of bindweed vines lined 

 with softer vines and leaflets of same 

 weed. Its outer form was very en- 

 longated, some branches measuring 

 over one foot long while the widest 

 dimension was five inches outside. 

 This nest contained four eggs, incuba- 

 tion slightly begun; two of the eggs 

 were very clearly marked, fine speci- 

 mens, the third was considerable 

 lighter and the fourth was almost 

 unmarked. 



No. 8, Date, June 7, 1912; In tract 

 of scattering timber built in a clump 

 of snowberry bushes; situated 20 

 inches above the ground on and be- 

 tween small twigs. A neat, compact 

 nest composed of weedstems, grasses 

 and hairs sparsingly lined with black 

 horse hairs and one feather of a Sooty 

 Grouse. It contained four eggs which 

 were incubated about a week. 



No. 9, Date, June 9, 1912; At the 

 edge of a clearing in a partly swamp- 

 land hillside built in the horizontal 

 fork of a hazel bush, 28 inches above 

 the ground; very well concealed in 

 the dense growth of bindweed and 

 rank ferns. This nest is a marvel of 

 compactness and size for this Warb- 

 ler; the walls are compact iy 2 to 2V 2 

 inches thick; it is neatly and deeply 

 cupped. The cavity measures two 

 inches in daimeter and 1% inches 

 deep. Into its composition have en- 

 tered, bindweed stems, several thistle 

 stems, ferns and grasses, lined with
