Js.mes Allen, of Freaee's Store, Ohio, has taken measures to secure a patent for an improvement in clover separators, the nature of which consists in a peculiar arrangement of what is called the " tail-boards " at the outer end of the shoe and sieves, and a chamber or passage containing a screen at the bottom of the shoe, by which arrangement the seed is prevented from passing off the upper screen with the chaff, and as thus more perfectly separated than heretofore.
