little flock, teaching them with infinite patience all that 

 they need to know of wood lore. He stands on guard 

 at every suspicious noise, and whistles his warning when 

 danger threatens. When their wing-feathers have devel- 

 oped and they can flutter up to a low branch in the bush, 

 they roost there instead of cuddling under the mother's 

 broad wings at night. But they remain with the parents 

 and evidently under discipline throughout the first six 

 or eight months of their existence. In the wintry 

 weather, when their mountain homes are covered deep 

 with snow, they often sleep huddled together deep in a 

 drift, waking to feed upon the buds of the coniferous 

 trees, but seldom seeking a lower level. They are the 

 hardy mountaineers, the children of the forest ranges.
