MISCELLANEOUS ARTICLES.

I he principal of these are, 1. The bruising-machine ;2. The straw-cutter; and, 3. The mill for making pot orpearl barley.

There are different sorts of machines for bruising grainfor the feeding of horses, one of which consists of two cast-metal rollers or cylinders, between twelve and sixteen incheslong, and generally from six to nine inches in diameter.These rollers must be turned in a lathe perfectly cylindrical,and quite straight in a longitudinal direction ; they are bothplaced into one frame in a horizontal position ; and, whendriven round, the circumference of ea^ch rolls upon that of theOther, by which means the grain is bruised or crushed, as itpasses down between them. Cylinders of this sort may be at-tached to any machine that is driven by water, by wind, or byhorses; there is a sloped hopper placed above them, for con-taining the grain, from which it is conveyed by a suspendedboard, in between the two cylinders. The frame in whichthese cylinders revolve is furnished with screw-bolts, by meansof which they can easily be placed at a greater or less dis-tance from each other ; and of course the grain can be moreor less bruised, as may be found necessary. There is an-other form of this machine, composed of one cylinder, fromnine to twelve inches long, and betwixt live and seven inchesin diameter; there is a concave breast equal in length to thiscylinder, and about five inches in breadth, by one inch thick;they are both made of malleable iron, case-hardened, andfiuted, or have small sharp teeth in a longitudinal direction.This breast is fixed in the frame with its concave or fluted
