These improvements consist in a pe culiar construction and arrangement of the cutters and in the manner by which the grain IS laid in proper order upon the ground after being cut. The cutters are placed in pairs in a spi ral curve round a shart, being set at right angles to it, and are carried round as tbe shaft rotates, c u tt in g tbe grain in their revolution. Directly behind the shaft is the front board of the machine, on the upp e r part of which are s e ri e s o f p oin ted fin g ers, w hich are slotted to r ec eive the c utte rs as the shaft re vo lv e s , and are set at such an angle that the grass o r grain is b e n t i n a suitahle direction affixed a

Measures to secure a patent for an impro ved construction of the above, by which it is rendered more suitable for certain kinds or work have been taken by Thomas J. Alex,.n der, of Westerville, Ohio. The advantage or this plan is that logs can be sawn directly in to broom bandies, chair rounds; &c., without having been preViously sawn � into planks, thus economising an important item of ex pense. One horizontal and two vertical saws adjusted in relative positions, serve to cut the sticks from the logs, the vertical saws being placed underneath the horizontal saw and nearly touching it.
