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... more...

Chapter I. 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... more...

Last Bull That was what two grim old sachems of the Dacotahs had dubbed him; and though his official title, on the lists of the Zoölogical Park, was “Kaiser,” the new and more significant name had promptly supplanted it. The Park authorities—people of imagination and of sentiment, as must all be who would deal successfully with wild animals—had felt at once that the name aptly embodied the... more...

Identification is Important Identifying waterfowl gives many hours of enjoyment to millions of people. This guide will help you recognize birds on the wing—it emphasizes their fall and winter plumage patterns as well as size, shape, and flight characteristics. It does not include local names. Recognizing the species of ducks and geese can be rewarding to birdwatchers and hunters—and the ducks.... more...

UNDERTHE MAPLESITHE FALLING LEAVESThe time of the falling of leaves has come again. Once more in our morning walk we tread upon carpets of gold and crimson, of brown and bronze, woven by the winds or the rains out of these delicate textures while we slept. How beautifully the leaves grow old! How full of light and color are their last days! There are exceptions, of course. The leaves of most of the... more...

THE BLUEBIRD It is sure to be a bright March morning when you first hear the bluebird's note; and it is as if the milder influences up above had found a voice and let a word fall upon your ear, so tender is it and so prophetic, a hope tinged with a regret. There never was a happier or more devoted husband than the male bluebird. He is the gay champion and escort of the female at all times, and... more...

In his excellent taxonomic treatment of the tree squirrels of Mexico and Central America, Nelson (Proc. Washington Acad. Sci., 1:15-110, 2 pls., May 9, 1899) recognized three subspecies of red-bellied squirrels, Sciurus aureogaster aureogaster F. Cuvier, Sciurus aureogaster hypopyrrhus Wagler, and Sciurus aureogaster frumentor Nelson. In his lists of specimens examined, Nelson (op. cit.:42 and 44)... more...

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...

I wish to speak a word for Nature, for absolute freedom and wildness, as contrasted with a freedom and culture merely civil—to regard man as an inhabitant, or a part and parcel of Nature, rather than a member of society. I wish to make an extreme statement, if so I may make an emphatic one, for there are enough champions of civilization: the minister and the school committee and every one... more...

Medicines may be administered to cattle in many ways. The channel and method of administration depend on whether a general or local effect is desired, the condition of the animal, and the nature of the medicine that is to be given. The easiest method, and therefore the most common, is to give ordinary remedies by the mouth with the food, with drink, or separately. There, are, however, some conditions... more...
