IN preparing maps showing the geographic distribution of North American lagomorphs, some conflicting statements in the literature have led us to examine the pertinent specimens of the Florida cottontail and the Audubon cottontail with results as given below. The study here reported upon was aided by a contract between the Office of Naval Research, Department of the Navy, and the University of Kansas (NR 161–791). Unless otherwise indicated,... more...

INTRODUCTION Does the fact that a weak mortal sought an unprofaned sanctuary—an island removed from the haunts of men—and there dwelt in tranquillity, happiness and security, represent any just occasion for the relation of his experiences—experiences necessarily out of the common? To this proposition it will be for these pages to find answer. Few men of their own free will seek seclusion, for does not man belong to the social... more...

CHAPTER ONE HOW OUR FIRST ANCESTORS LIVED Before these fields were shorn and tilledFull to the brim our rivers flowed;The melody of waters filledThe fresh and boundless woods;And torrents dashed, and rivulets play'd,The fountains spouted in the shade. William Cullen Bryant,quoted in American Forestry, XIV. 520 The earth is our home. It is a great treasure house filled with the most wonderful things. Although people have lived on the... more...

THE HOLT AMONG THE ALDERS. I first saw Lutra, the otter-cub, while I was fishing late one summer night. Slow-moving clouds, breaking into fantastic shapes and spreading out great, threatening arms into the dark, ascended from the horizon and sailed northward under the moon and stars. Ever and anon, low down in the sky, Venus, like a clear-cut diamond suspended from one of its many twinkling points, glittered between the fringes of the clouds, or... more...

PREFACE. The primary object of the present work, is to give as correct and comprehensive a view of the animals composing the Ox Tribe, as the present state of our knowledge will admit, accompanied by authentic figures of all the known species and the more remarkable varieties. Although this genus (comprising all those Ruminants called Buffaloes, Bisons, and Oxen generally,) is as distinct and well characterised as any other genus in the animal... more...


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 incisors of the calf. As the animal... more...

DEVELOPMENT OF THE DIGESTIVE CANAL OF THE AMERICAN ALLIGATOR By ALBERT M. REESE Professor of Zoology, West Virginia University In a previous paper () the writer described the general features in the development of the American Alligator; and in other papers special features were taken up in more detail. In the present paper the development of the enteron is described in detail, but the derivatives of the digestive tract (liver, pancreas,... more...

INTRODUCTION This beautiful volume has been written for a good purpose. I had the pleasure of reading the proof-sheets of the book while in the Yellowstone National Park, where no gun may be lawfully fired at any of God's creatures. All animals there are becoming tame, and the great bears come out of the woods to feed on the garbage of the hotels and camps, fearless of the tourists, who look on with pleasure and wonder at such a scene. "The... more...

Chapter I. THE AGE OF REPTILES. Its Antiquity, Duration and Significance in Geologic History. Palæontology deals with the History of Life. Its time is measured in geologic epochs and periods, in millions of years instead of centuries. Man, by this measure, is but a creature of yesterday—his "forty centuries of civilization" but a passing episode. It is by no means easy for us to adjust our perspective to the immensely long spaces... more...

INTRODUCTION One of the effects of the modern advance in natural science has been greatly to increase the attention which is devoted to the influences that the conditions of diverse peoples have had upon their development. Man is no longer looked upon, as he was of old, as a being which had been imposed upon the earth in a sudden and arbitrary manner, set to rule the world into which he had been sent as a master. We now see him as one of the... more...
