ness the persevering pair had built and reared a brood. The 

 finding of the last nest happened by chance. Mr. Knox had 

 descended a shaft connected Avith the tunnel and was pass- 

 ing along the level with a lighted candle when he saw a bird 

 fly from close before him, and aided by the light which he 

 carried, the nest, with four large young, was found, but left 

 undisturbed. (C. W. K.) 



Tachycineta bicolor. 



Tree Swallow. — A few years ago I found a nest with 

 young in a crevice under the projecting and decayed deck 

 of a lumber lighter, moored in Oakland harbor. 



Vireo huttoni. 



Hutton's Vireo. — A pair of vireos built this year in the 

 outer branches of a live oak, only a few feet above the ex- 

 haust pipe from a steam pump, where at times they were 

 compelled to suspend work, owing to the dense vapor which 

 enveloped them. Four eggs were laid in this nest. (C. W. K.) 



Cistothorus palustris. 



Long-billed Marsh Wren. — A conspicuous nest, con- 

 taining eggs, was woven among the almost leafless branches 

 of a young willow, five feet above a fresh water marsh. The 

 false nests were built as usual, but in the coarse grass near 

 by. (A. M. I.)
