POCKET , a small bag, particularly a bag-like receptacle either fastened to or inserted in an See also:article of clothing . As a measure of capacity " pocket" is now only used for hops; it equals 168 lb . The word appears in See also:Mid . Eng. as poket, and is taken from a See also:Norman diminutive of O . Fr. poke, pouque, mod. poche, cf . " pouch." The See also:form " poke " is now only used dialectically, or in such proverbial sayings as a " See also:pig in a poke," and possibly in the " poke-See also:bonnet," the See also:coal-See also:scuttle bonnet fashionable during the first See also:part of the 19th See also:century, and now worn by the See also:female members of the Salvation See also:Army; more probably the name of the bonnet is connected with " poke," to thrust forward, dig . The origin of this is obscure . Dutch has poken, gook, a See also:dagger; See also:Swedish pdk, a stick . POCKET-See also:GOPHER (i.e. pouched See also:rat), the name of a See also:group of, chiefly See also:North, See also:American rat-like rodents, characterized by the See also:possession of large cheek-pouches, the openings of which are See also:external to the mouth; while their inner See also:surface is lined with See also:fur . The cheek-See also:teeth, which comprise two pairs of premolars and three of molars in each See also:jaw, are in the form of See also:simple prisms of See also:enamel, which do not develop roots . The fore and See also:hind limbs are of approximately equal length, but the second and third front-claws are greatly enlarged, and all the claws are furnished at the See also:base with bristles . The eyes are small, and the external ears rudimentary .
Pocket-gophers, which typify a See also:family, the Geomyidae, spend the whole of their See also:time underground, and are specially organized for such a mode of existence, their powerful claws being adapted for digging, while the bristles on the toes prevent the See also:earth from passing between them
.
The upper incisor teeth are employed to loosen the ground, like a See also:fork; and the little rodents are able to move both backwards and forwards in their runs
.
The cheek-pouches are employed solely in carrying See also:food, which consists largely of roots
.
In the typical genus Geomys the upper incisors are grooved, but in the allied Thomomys they are smooth
.
The See also:common pocket-gopher, Geomys bursarius, of the See also:Mississippi Valley See also:measures about 8 in. in length, with a tail of between 2 and 3 in.; its See also:colour being rufous See also: |
