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...

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...

RULE I. ON THE CONSTRUCTION OF A BEE-HIVE. A bee-hive should be made of sound boards, free from shakes and cracks; it should also be planed smooth, inside and out, made in a workmanlike manner, and painted on its outside. REMARKS. That a bee-hive should be made perfect, so as to exclude light and air, is obvious from the fact, that the bees will finish what the workman has neglected, by plastering up... more...

INTRODUCTION In the preparation of a book of this nature, to be used in the grade schools, we realize that the one fundamental thing to keep in mind is the economic importance of the insect, be it good or bad. The child wants to know what is good and what is bad and how he can make use of the good and how he can get rid of the bad. And yet there is something more associated with the life, work and... more...

BIRDS OF THE SNOW No fact of natural history is more interesting, or more significant of the poetry of evolution, than the distribution of birds over the entire surface of the world. They have overcome countless obstacles, and adapted themselves to all conditions. The last faltering glance which the Arctic explorer sends toward his coveted goal, ere he admits defeat, shows flocks of snow buntings... 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...

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...

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...

INTRODUCTION Somethirty years ago, while out on one of his landlooking trips in the woods of Northern Michigan, my father came upon a little lake which seemed to him the loveliest that he had ever seen, though he had visited many in the course of his explorations. The wild ponds are very apt to be shallow and muddy, with low, marshy shores; but this one was deep and clear, and its high banks were... 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...
