summer. Since they love a cool retreat in 

 which to breed it will be correctly inferred 

 that the latter locality is the higher of the 

 two; yet in winter when the birds flee south 

 to escape the cold, they are still found plenti- 

 fully in the Pennsylvania locality while they 

 are absent from the other. Members living 

 within a hundred and fifty miles of the forty- 

 second parallel are requested to aid in this in- 

 vestigation, by sending answers to one or all 

 of the following questions : What is your 

 latitude? What is your altitude? Does the 

 Snowbird winter in your locality? Is is pres- 

 ent in both mild and severe winters ? Is it 

 a sumjner resident in your vicinity? If you 

 are north of the forty-second parallel, to what 

 do you attribute its presence in winter — food- 

 supply, altitude, plentiful shelter, the near- 

 ness of large bodies of water, a river-valley 

 extending north and south, etc. If near this 

 parallel and the birds do not winter, to what 

 do you attribute their absence? If south of 

 this parallel, and the birds breed, to what do 

 you attribute the fact? In this investigation 

 every miember in the territory covered can 

 help, for all know the Juncos. Even if you 

 can answer but one of the above questions it 

 will add to the results. A full report of the 

 matter will be published and everyone who
