the time continuing lier e;ill. Then occurred one of the prettiest sights that I ever wit- 

 nessed, for a dozen or more of the young Grouse came suddenly into life, all appearing in 

 the area of a few square feet. So quickly did they sjiring up, that every leaf seemed trans- 

 formed into a little brown Partridge and although I watched carefully to see where; they 

 had hidden themselves, I was no wiser when all were out than before. The little brood 

 gathered about tlieir parent and she led them away at a fast rate to the nearest thicket, 

 evidently thinking the neighborhood dangerous. In fact, she was in so much haste to leave 

 it that the little ones could not keep up Avith her by running, some being obliged to use 

 tlieir wings, and I was surprised to see that, even at that early age, they could fly two or 

 three 3'ards, especially when they started from a slight elevation. 



The young follow their parent and are cared for by her, until they are nearly or quite 

 fully grown; then all remain in company until the following spring, as related. 



The drumming of the RufTed Grouse has attracted the attention of nearly all ornithol- 

 ogists and several explanations have been given, regarding the method by wliich this sin- 

 gular sound is produced. Some say that the bird strikes a log or stone with its wings; 

 others, that it strikes its body; then again, it has been asserted that the wings are struck 

 together over the back. Mr. Brewster who is a very careful observer, says that when drum- 

 ming, the bird sits upright with its tarsus horizontal to the log or surface on which it 

 rests, with the wings extended, and that it does not strick anything, perceptible, with 

 these members, but that the sound is produced by the out-spread wings being brought sud- 

 denly downward against the air. This is certainly quite a plausible theory, but I am in- 

 clined to think that the sound is vocal; that the wings merely aid in producing it or are 

 beaten downward as accessories to the note, just as a rooster crows, flapping its wings at 

 the same time. The laryngeal muscles are certainly constructed in a manner similar to 

 those of the Pinnated Grouse, the toolings of which are vocal. I have heard (he Rullld 

 Grouse drum from early spring until late in autumn. 



FAMILY III. PERDICID^. THE QUAILS, ETC. 



Head and neck, campletcljj feathered, but the tortus is naked, as is also the i-pcce ab^ve 

 the nostrils. Top of keel, not eqitatlinrj in length the depth of the inner marginal indenta- 

 tions. 



The terminal expansion of the furcula is narrow, produced downward, and approxi- 

 mates quite closely to the sternum. LTpper process of manubrium, not produced forward. 

 The costal process is Aery narrow, tapering toward point which is not rounded. The bone 

 at the extreme outer edge of sternum, beyond the outer marginal indentation, is not very 

 wide. Tliere is a moderately large perforation through the manubrium, and the sternum in 

 front of keel, is deeply furrowed, but there is no very prominent central ridge.
