 small creature, laying but few eggs and with but a slight 

 tendency to accumulate fat. From this parent stock varieties 

 have been bred which attain in some cases to eight or ten 

 times the weight of the ancient form. They have, moreover,

The Original Jungle Fowl yCailus t>ii>t/civa) and Some of His Domestic Descendants 



It is an interesting fact that our barnyard fowl is the only 

 species of a large family of birds which has been truly domes-
