The jack rabbits of the United States

Abstract

The Great Plaius and deserts of the western United States are inhabited by several species of large hares, commonly known as 'jack rabbits.' These rabbits occur almost everywhere, except in the higher mountains and in wooded regions, from the ninety-fifth meridian west to the Pacific, and from the Plains of the Saskatchewan soutliward over the table-land of Mexico to the Isthmus of Tehuantepec. The resem blance of their large ears to those of the well-known pack animal of the West lias suggested the common names of 'jackass hares,' 'jack rabbits," or 'jacks.' In some parts of California jack rabbits are called 'narrow-gauge mules' and 'smull mules,' but fortunately these absurd terms are very local, and not likely to come in general use. 1 n the Southwest and beyond the Kio Grande the large hares are called 'liebres* by the Mexicans, to distinguish them from the cotton-tail rabbits, or 'couejos.' * Several small shotgun drives took place about 1882 and 1883.-J. Ellis McLellan. » Another drive announced for April 15, IS.'^S. " Third di-ivo of the season. Another was planned for^farch 13. 1892, but no repin-t has been received. ' Six drives in all took plac(> during February, Manli. and .Vpril. in which 20,000 were killed. ' About 1,000 more estimated to have escaped. Anollier drive planned for March 18. UESULTS OF THE DRIVES. Altliougli it is practically impossible to give all the rabbit drives which have occurred in California during-the last eight years, still this list of 155 drives, including the more important ones during the twenty years from 1875 to 1895, should be sufficient to show the progress of

Planar Pyrochlore, Quantum Ice and Sliding Ice

“…11 However, it has a unit cell of only two spins, is two dimensional, and has allowed exact diagonalisations of a good number of finite size systems of up to 36 spins. Such diagonalisations have very recently been carried out by Palmer and Chalker 13 and by Fouet et al 14 and other workers have also recently studied this system by several techniques.

The economic value of ensemble forecasts as a tool for risk assessment: From days to decades

“…Because the equations of motion are nonlinear, the dispersion of an ensemble forecast will be dependent on the initial state: small dispersion indicating high predictability, and vice versa. In the past few years, ensemble prediction has become an established part of weather and climate prediction, from days to decades (see, for example, Palmer 2000).…”

The Study of Epidemic Diseases Among Wild Animals

“…In the western parts of the United States, similar epidemics occur amongst wild snowshoe rabbits and jack rabbits (Nelson, 1909;Palmer, 1896;Warren, 1910), and whereas we know nothing about the nature of the diseases which attack the Canadian snowshoe rabbit over an area of some millions of square miles, in the United States some light has been thrown on the matter by recent work. In certain cases rabbits have been found dying of tularaemia, a bacterial disease which is highly infectious to man (Green, 1928;Redington, 1928).…”

“…Subject to occasional epidemics on a large scale in many parts of their range; Western U.S.A. in general (Nelson, 1909), Colorado (Warren, 1910), California, Nevada, Idaho, Utah, and Washington (Palmer, 1896). Proved to be.dying of tularaemia in Utah in 1919 (Redington, 1928).…”
