No picture of early spring among the farms, with the fields of dry 

 cornstalks and the smoky, budding wood-lots, marked off by rail 

 fences, is complete without an occasional stiff whirr of wings in the 

 brush, a scudding of quick feet in the rustling leaves, and the distant 

 clear whistle, bob- white. 



The quail are in pairs no^v, and unless near enough together for 

 their low conversational quit, quirk, qneet, are sure to be calling back 

 and forth in loud whistles from the fence tops, the stone piles, or 

 low branches of trees. A little later the calling is hushed and the 

 male may be seen hurrying about alone, or the two running mys- 

 teriously under the bushes ; and still later there is a flock of little 

 brown fluffy chicks to be led and guarded. By themselves they 

 are a quiet, happy family, but when an intruder appears, all is excite- 

 ment and confusion. There are two sputtering, fluttering, scolding 

 old birds trying to lure or scare you away in .several directions at 

 once, and there is a scurrying flock of chicks, under your feet one 

 moment, gone the next. They take to their heels now. but in a 

 short time their (piills sprout, and then when disturbed they take to 

 wing like a lot of bumblebees. 



As the summer passes the broods often join in largrr flocks, and 

 when thi'V get scattered the call-whislk', hob-tchite, is heard again
