 are the earliest and latest dates available from any locality in the state. Another 

 July date is that of six eggs found at Milk River, July 6, 1874 (Coues, 1874b, 

 p. 582).

 collared Longspur, but it has been found also in one locality in the mountain 

 valleys, west of the first ranges. This locality is in Broadwater County, about
