THE BLUE JAY. URING about three-fourths of the year the American Jay is an extremely tame, noisy and even obstrusive bird in its habits. As the breeding season approaches he suddenly becomes silent, preparing the nest in the most secluded parts of his native forests, and exercising all his cunning to keep it concealed. He is omniverous but is especially fond of eggs and young birds. The Jay may be... more...

SECTION I. In discussions of pathological conditions contributing to lameness in the horse, cause is generally classified under two heads—predisposing and exciting. It becomes necessary, however, to adopt a more general and comprehensive method of classification, herein, which will enable the reader to obtain a better conception of the subject and to more clearly associate the parts so grouped... more...

PREFACE. Before the reader decides that an apology is necessary for the introduction of another work on bees into the presence of those already before the public, it is hoped that he will have the patience to examine the contents of this. The writer of the following pages commenced beekeeping in 1828, without any knowledge of the business to assist him, save a few directions about hiving, smoking them... more...

Information about osteological changes in the groups of reptiles that gave rise to mammals is preserved in the fossil record, but the musculature of these reptiles has been lost forever. Nevertheless, a reasonably accurate picture of the morphology and the spatial relationships of the muscles of many of these extinct vertebrates can be inferred by studying the scars or other marks delimiting the... more...

CHAPTER XXI. THE MOLUCCAS—TERNATE. ON the morning of the 8th of January, 1858, I arrived at Ternate, the fourth of a row of fine conical volcanic islands which shirt the west coast of the large and almost unknown island of Gilolo. The largest and most perfectly conical mountain is Tidore, which is over four thousand Feet high—Ternate being very nearly the same height, but with a more rounded and... 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...

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...

The Swan. The Swan is a very beautiful bird. It is generally white, though a black swan has been discovered in Australia. It is not very often seen in this country. It was brought from Asia and Eastern Europe into England—from whence, most probably, a few specimens have been introduced into this country. The Swan is very graceful in the water, but on land it is an awkward waddler. The Coot is... more...

CHIRP THE FIRST. The winter of 1878 was certainly an unusually dreary one, and so thought a remarkably fine young Blackbird, as he perched one morning on the bare bough of a spreading lime-tree, whose last brown leaf had fallen to the ground some weeks before. With the exception of the Scotch firs and other fortunate evergreens, there was nothing to be seen on all sides but leafless branches standing... more...

Marco Polo, had he confined himself to a sober narration of his travels, would have left to posterity a valuable record of the political institutions and national customs of the peoples of his day in the Far East. He was not satisfied with doing this, but added to his narrative a number of on-dit more or less marvellous in character, which he collected from credulous or inventive persons with whom he... more...
