In 1928 when Miller and Allen (Bull. U. S. Nat. Mus., 144) published their revisionary account of American bats of the genus Myotis, the black myotis, Myotis nigricans, was known no farther north than Chiapas and Campeche. Collections of mammals made in recent years for the Museum of Natural History of The University of Kansas include specimens of M. nigricans from eastern Mexico as far north as... more...

PAL In the depths of the green wilderness, where dark spruce and hemlock guard the secrets of the trail, are still to be found wild creatures who know little of man and who regard him with more of curiosity than of fear. Woodland ponds, whose placid waters have never reflected the dark lines of a canoe, lie like jewels in their setting of green hills; ponds where soft-eyed deer come down to drink at... 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...

DETERMINING THE AGE OF CATTLE BY THE TEETH. The age of cattle can be approximated closely by the appearance, development, and subsequent wear of their second incisor teeth. Cattle have eight incisor teeth, all in the lower jaw. In the calf at birth two or more of the temporary or first incisor teeth are present. With the first month the entire eight incisors have appeared.Fig.1.—Internal face of... more...

OUR PETS. This is Pol-ly's own cat, Top-sy. She looks ve-ry prim and quiet; but if you play with her, you will find she is a ve-ry mer-ry lit-tle cat. She will jump up-on the ta-ble at break-fast, and run off with Pol-ly's toast; and if mam-ma be wri-ting a let-ter, Top-sy will steal soft-ly a-long the arm of the so-fa, and rub her paw o-ver the last word mam-ma has writ-ten, and make a great... 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 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 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...

In his excellent taxonomic treatment of the tree squirrels of Mexico and Central America, Nelson (Proc. Washington Acad. Sci., 1:15-110, 2 pls., May 9, 1899) recognized three subspecies of red-bellied squirrels, Sciurus aureogaster aureogaster F. Cuvier, Sciurus aureogaster hypopyrrhus Wagler, and Sciurus aureogaster frumentor Nelson. In his lists of specimens examined, Nelson (op. cit.:42 and 44)... more...
