might even be made a source of some little revenue, instead of a 
burden and a pest; they are to be had in practically unlimited 
numbers, and could be sold by the city to such persons as might 
desire to use them for sporting purposes. 
The present article is to be regarded as a mere outline of the 
important subject. I have collected a voluminous mass of testi- 
mony during the past two or three years, which I intend to 
digest, in order to place the whole matter in its true light on per- 
manent record, in treating of the species in the “ Birds of the 
Colorado Valley.” For the plague has spread even to that

over whose tops the city is slowly advancing, throwing out the 
sentinels of scattered houses, and to our left spreads out its 
glorious Bay of San Francisco, glowing under the summer sun. 
The bay is broad here, and the coast range of Alameda county 
looks very distant and misty. Far away to the south, beyond 
the San Bruno hills, beyond the long stretch of lowland, backed
