ROLL, in the Manufactories, fomething wound and 

 folded up in a cylindrical form. 



Few ilufFs are made in rolls, except fatliu .-., gauzes, and 

 crapes, which are apt to break, and take plaits not eafy to 

 be got out, if folded otherwife. Ribbands, however, and 

 laces, galloons, and padliaa of all kinds, are thus rolled. 



The ancients made all their books up in form of rolls, or 

 littlr columns ; and, in Cicero's time, the libraries con- 

 lifted wholly of thofe rolls. The dcarnefs of parchment, 

 and the cheapnefs of papyrus, of which the rolls were 

 made, was the reafon that fcarcely any but paper rolls were 

 ufed. 



Voflius fays, they palled feveral (hects end to cud, when 

 filled on one fide, and rolled them up together, beginning 

 with the lalt, which they called umbilicus, and to which 

 they fattened an ivory or boxen (lick, to fultain the roll. 



To the other extremity they palled a piece of parchment, 

 tu cover and preferve it. 



Theie rolls were placed in the libraries perpendicularly 

 to the horizon. The Jews flill preferve the ancient ufagc 

 of rolls for the books they read in the fynagogues. 



Roll, To, in Military Language, is to continue one uni-

 of time. When a line is advancing in full front, or in echellons, 

 for any conlidcrable diflance, the mufic of one regulating 

 battalion may, at interval?, be permitted to play for a few 

 feconds at a time, and the drums of the other battalions 

 may be allowed occalionally to roll : drums like wife roll 

 when troops are advancing to charge. For the method of 

 performing the roll, fee licit, under Duum.

 Roll of Tobacco, is tobacco in the leaf, twifted in the 

 mill, and wound twill over twift, about a (tick or roller. 



The generality of tobacco in America is there fold in

 England, Spain, France, and Holland that it is cut. Roll 

 tobacco is what is chiefly ufed, both for chewing and 

 rafping. See Tobacco.

 Roll, Rotulus, in Law, denotes a fchedule of paper or

Of thefe there are, in the Exchequer, feveral kinds ; viz. 

 the great -wardrobe-roll, the coferer's-re/l, the fubfidy-roll, 

 &c. 



The word is formed from the French rolle, of the Latin

 were anciently written on papers, or parchments, fewed or 

 glued together, and thus rolled up : whence the word enrol, 

 and the like.
