The subject of inheritance is an immense one, and has been treated by many authors. One work alone, 'De l'Hérédité Naturelle,' by Dr. Prosper Lucas, runs to the length of 1562 pages. We must confine ourselves to certain points which have an important bearing on the general subject of variation, both with domestic and natural productions. It is obvious that a variation which is not... 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...

CHAPTER 1. SUPPLY AND DEMAND. For years there has been a belief that the supply of fur-bearing animals would soon be inadequate to the demand. This belief is well founded and is apparent when the fact is known that the natural haunts and homes of the fur-producing animals are becoming less each year. The draining of swamps and marshes is destroying the homes and breeding places of muskrat and to a... more...

FOREWORD "And in the lion or the frog—In all the life of moor or fen—In ass and peacock, stork and dog,He read similitudes of men." More and more science is being taught in a new way. More and more men are beginning to discard the lumber of the brain's workshop to get at real facts, real conclusions. Laboratories, experiments, tables, classifications are all very vital and all very... more...

The naturalists of yesterday and the naturalists of to-day. — The study of animals, plants, rocks, and of natural objects generally, was formerly called “natural history”; but this term is tending to disappear from our vocabulary and to give place to the term “natural sciences.” What is the reason of this change, and to what does it correspond? for it is rare for a word to be modified in... more...

Our aim is to bring up to date the list of kinds of bats actually known from Barro Colorado Island, Panamá. In 1952 Samuel T. Dickenson, Marguerite Schultz, George P. Young, and E. Raymond Hall spent the first 17 days of April (except Mrs. Schultz who left on April 8) on Barro Colorado Island. On eight evenings a silk net, 30 feet long and 7 feet high with a ¾-inch mesh, was stretched in an open... 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...

CHAPTER I. "Bless me, I do believe I have been asleep!" said a squirrel, one fine morning in early spring, when the delicious warmth of the sun had reached him in his winter retreat, and roused the lazy little fellow from a two months' nap. The truth is, that he and his family had fallen asleep at the first setting in of the cold weather, and had passed the dismal winter in a state of... more...

CHAPTER I THE LITTLE FURRY ONES THAT SLIDE DOWN HILL In the brown, balsam-smelling log cabin on the shores of Silverwater, loveliest and loneliest of wilderness lakes, the Babe's great thirst for information seemed in a fair way to be satisfied. Young as he was, and city-born, the lure of the wild had nevertheless already caught him, and the information that he thirsted for so insatiably was all... more...

INTRODUCTION. A considerable portion of the contents of the present volume formed the zoological section of a much more comprehensive work recently published, on the history and present condition of Ceylon. But its inclusion there was a matter of difficulty; for to have altogether omitted the chapters on Natural History would have impaired the completeness of the plan on which I had attempted to... more...
