JOHN BURROUGHS John Burroughs was born April 3, 1837, in a little farmhouse among the Catskill Mountains. He was, like most other country boys, acquainted with all the hard work of farm life and enjoyed all the pleasures of the woods and streams. His family was poor, and he was forced at an early date to earn his own living, which he did by teaching school. At the age of twenty-five he chanced to read... 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...

In the examination of a sick horse it is important to have a method or system. If a definite plan of examination is followed one may feel reasonably sure, when the examination is finished, that no important point has been overlooked and that the examiner is in a position to arrive at an opinion that is as accurate as is possible for him. Of course, an experienced eye can see, and a trained hand can... more...

In the academic year of 1947-48 Montague studied the geographic variation in Thomomys talpoides of Wyoming. His study was based upon materials then in the University of Kansas Museum of Natural History. Publication of the results was purposely delayed until previously reported specimens from certain adjacent areas, especially in Colorado, could be examined. In the autumn of 1950 one of us, Hall, was... more...

Preface. I have been called upon to write illustrative sketches to a series of engravings, designed by an eminent artist. In performing my part of the work I have thrown the Mammalia into twenty-four groups—corresponding more or less to the picture designs—and have dwelt chiefly on the geographical distribution of the animals. The Cetaceae and Vespertilionidae are properly omitted. In the groups... more...

INTRODUCTION Nature in her ever-constant, ever-changing phases is indispensable to man, his whole existence depends upon her, and she influences him in manifold ways, in mind as well as body. The physical character of a country is reflected in its inhabitants; the one factor of climate alone gives a very different outlook to northerner and southerner. But whereas primitive man, to whom the darkness of... more...

I. THE FEEDING OF CATTLE, Etc. (Read before the Chamber of Agriculture.) As my friend Mr Stevenson and some other members of the Chamber of Agriculture have expressed a desire that I should read a paper on my experience as a feeder of cattle, I have, with some hesitation, put together a few notes of my experience. I trust the Chamber will overlook the somewhat egotistical form into which I have been... more...

The mountains of Coahuila, which are part of the Rocky Mountain-Sierra Madre Oriental Axis, extend in a north-south direction and divide the lower lands into two areas, a larger one, a part of the Central Plateau, to the... more...

The Freedom of the Black-faced Ram n the top of Ringwaak Hill the black-faced ram stood motionless, looking off with mild, yellow eyes across the wooded level, across the scattered farmsteads of the settlement, and across the bright, retreating spirals of the distant river, to that streak of scarlet light on the horizon which indicated the beginning of sunrise. A few paces below him, half-hidden by a... more...
