Introduction GROWING NUTS IN THE NORTH Only a few books have been written on the subject of nut trees and their bearing habits, and very little of that material applies to their propagation in cold climates. For these reasons I am relating some of the experiences I have had in the last thirty-two years in raising nut trees in Wisconsin. To me, this has been a hobby with results both practical and... more...

CHAPTER I HOW TREES GROW AND MULTIPLY   The trees of the forest grow by forming new layers of wood directly under the bark. Trees are held upright in the soil by means of roots which reach to a depth of many feet where the soil is loose and porous. These roots are the supports of the tree. They hold it rigidly in position. They also supply the tree with food. Through delicate hairs on the roots, they... more...

CHAPTER I. PHYSICAL GEOGRAPHY. From a look at a globe or a map of the Eastern hemisphere, we shall perceive between Asia and Australia a number of large and small islands forming a connected group distinct from those great masses of land, and having little connection with either of them. Situated upon the Equator, and bathed by the tepid water of the great tropical oceans, this region enjoys a climate... more...

IMPORTANCE OF RODENT GROUPS. As the serious character of the depredations by harmful rodents is recognized, State, Federal, and private expenditures for their control increase year by year. These depredations include not only the attacks by introduced rats and mice on food materials stored in granaries, warehouses, commercial establishments, docks, and private houses, but also, particularly in the... more...

CHAPTER I. VIOLA. 1. Although I have not been able in the preceding volume to complete, in any wise as I desired, the account of the several parts and actions of plants in general, I will not delay any longer our entrance on the examination of particular kinds, though here and there I must interrupt such special study by recurring to general principles, or points of wider interest. But the scope of... more...

CHAPTER I It is in spring that wild birds make their strongest appeal to the human mind; in fact, the words "birds" and "spring" seem almost synonymous, so accustomed are we to associate one with the other. All the wild riotous singing, all the brave flashing of wings and tail, all the mad dashing in and out among the thickets or soaring upward above the tree-tops, are impelled by the... more...

I The Cute Coyote AN EXEMPLARY LITTLE BEAST, MY FRIEND THE COYOTE If you draw a line around the region that is, or was, known as the Wild West, you will find that you have exactly outlined the kingdom of the Coyote. He is even yet found in every part of it, but, unlike his big brother the Wolf, he never frequented the region known as Eastern America. This is one of the few wild creatures that you can... more...

PREFACE. There is no lack of good manuals of botany in this country. There still seems place for an adequately illustrated book of convenient size for field use. The larger manuals, moreover, cover extensive regions and sometimes fail by reason of their universality to give a definite idea of plants as they grow within more limited areas. New England marks a meeting place of the Canadian and... more...

IN 1949, for the Museum of Natural History of the University of Kansas, Mr. John A. White collected two specimens of the species Microtus montanus in the Bitterroot Valley of Montana, that did not fit the description of any named subspecies. These were laid aside until we could examine the additional specimens from Montana in the Biological Surveys collection in the United States National Museum, some... more...

In coming before the public with a newly made edition of my writings, what can I say to my reader at this stage of our acquaintance that will lead to a better understanding between us? Probably nothing. We understand each other very well already. I have offered myself as his guide to certain matters out of doors, and to a few matters indoor, and he has accepted me upon my own terms, and has, on the... more...
