DETERMINING THE AGE OF CATTLE BY THE TEETH. The age of cattle can be approximated closely by the appearance, development, and subsequent wear of their second incisor teeth. Cattle have eight incisor teeth, all in the lower jaw. In the calf at birth two or more of the temporary or first incisor teeth are present. With the first month the entire eight incisors have appeared.Fig.1.—Internal face of... more...

I. FOX-WAYS. Did you ever meet a fox face to face, surprising him quite as much as yourself? If so, you were deeply impressed, no doubt, by his perfect dignity and self-possession. Here is how the meeting generally comes about. It is a late winter afternoon. You are swinging rapidly over the upland pastures, or loitering along the winding old road through the woods. The color deepens in the west; the... more...

THE DISOBEDIENT WOODPECKER ONG, long ago, at the beginning of things, they say that the Lord made the world smooth and round like an apple.

BIRDS IN CAPTIVITY. It was our intention in this article to give a number of instances of a pathetic nature concerning the sufferings of the various species of birds which it has been, and still is, a habit with many people to keep confined in cages totally inadequate for any other purpose than that of cruelty.

PREFACE This little book is but another chapter in the shy 'wild life of the fields and woods' of which "Ways of Wood Folk" and "Wilderness Ways" were the beginning. It is given gladly in answer to the call for more from those who have read the previous volumes, and whose letters are full of the spirit of kindness and appreciation.

THE EAGLE. The Eagle is often called the King of Birds, and therefore it is of him that we ought to speak first. Very likely you have often seen eagles in the Zoological Gardens, and, if so, you know what noble looking birds they are. But they seem very sad in their prison-houses, to which no kindness can ever attach them. They are formed to soar boldly to the top of some lonely mountain height, and... more...
