CHAPTER I. GRACE CAMPBELL.   was a chilly Scotch spring day. The afternoon sun glistened with fitful, feeble rays on the windows of the old house of Kirklands, and unpleasant little gusts of east wind came eddying round its ancient gables, and sweeping along its broad walks and shrubberies, sending a chill to the hearts of all the young green things that were struggling into life. On the time-worn... more...

HAVING been called upon to make a close and careful examination of the geological formations in the eastern townships of Garthby, Wolf'stown, and Coleraine, situated in the province of Quebec, Canada, I gave special attention to the distribution of the Asbestos-bearing rocks (serpentine), which have been, in my opinion, heretofore only partially traced. Perhaps this was owing to the difficulties... more...

MERCHANTS occasionally go through a wholesome, though troublesome and not always satisfactory, process which they term "taking stock." After all the excitement of speculation, the pleasure of gain, and the pain of loss, the trader makes up his mind to face facts and to learn the exact quantity and quality of his solid and reliable possessions. The man of science does well sometimes to imitate... more...

One evening in the winter, some years ago, my brother came to my rooms in the city of Chicago bringing with him a book by Gertrude Stein. The book was called and, just at that time, there was a good deal of fuss and fun being made over it in American newspapers. I had already read a book of Miss Stein's called and had thought it contained some of the best writing ever done by an American. I was... more...

The plateau pocket gopher, Cratogeomys castanops, inhabits open lands from southeastern Colorado southward onto the Mexican Plateau as far south as southern San Luis Potosí and southeastern Zacatecas and southeastward to the Coastal Plain of northern Tamaulipas. This species occurs at elevations from as low as 26 feet at Matamoras in Tamaulipas to as high as 8700 feet in valleys of south-eastern... more...

The western harvest mouse, Reithrodontomys megalotis, inhabits most parts of the central Great Plains and adjacent regions of tall grass prairie to the eastward, shows a marked predilection for grassy habitats, is common in many areas, and is notably less variable geographically than most other cricetids found in the same region. R. megalotis occurs (see Hall and Kelson, 1959:586, map 342) from... more...

In the course of the preparation of a synopsis of the North American terrestrial microtines by one of us (Cockrum), and the completion of a Master's thesis on the geographical variation of the red-backed mice of Wyoming by the other (Fitch) we had occasion to study the red-backed mice of the southern Rocky Mountain region (see figure 1). Results of these studies are the recognition of two... more...

The hooded skunk, Mephitis macroura Lichtenstein, can be distinguished from the only other species in the genus, Mephitis mephitis Schreber, by the larger tympanic bullae, in the white-backed color phase by having some black hairs mixed with the white hairs of the back, and in the black-backed phase by having the two white stripes widely separated and on the sides of the animal instead of narrowly... more...

In his "Revision of the pocket mice of the genus Perognathus," Osgood (1900:18-20) reviewed the distribution, as then known, of Perognathus fasciatus and recognized two geographic races—Perognathus fasciatus [fasciatus] Wied-Neuwied in eastern Montana and Wyoming and adjacent parts of North and South Dakota, and Perognathus fasciatus infraluteus Thomas, known only from the type locality at... more...

Capitalized color terms in the following accounts are of Ridgway, "Color Standards and Color Nomenclature," Washington, D.C., 1912. The measurements of the skull that were used in this study were made as shown in White (1953:566, fig. 1). These are: Greatest length of skull, zygomatic breadth, cranial breadth, length of nasals, length of lower tooth-row, condylo-alveolar length of mandible, and... more...
