J. , of Three Rivers, Mich., certifies that an emery-wheel machinesaves from one-half to two-thirds the labor and time of furrow dressingwith the pick.

Operation of Grinding — Diameter of Burrs — Table of Rim Speeds — Speed of Grinding—Dress andQuality of Stone — Trouble in Grinding — Quality of Burr Flour. Operation of Grinding.—The grain falling into the eye is sweptaround between the two irons until caught between the stones. At first it isonly cracked.
