THE DRILL PLOUGH. 611

with a part of the apertures feen juft appearing from underthe brufhes, X, the’axis of the wheel.

Fig. 6 is a drawing of part of the tin cafe, nearly of the full di- menfions as to breadth and thicknefs, but only à fmall portion of the length; and is intended to fhew more diftin@ly the conftruétion Of it.

Fig. 2 reprefents a fide-view of one of the fix bridges lying over the holes at the‘bottom of the feed-box,:on each fide of which the brufhes are fixed, which ftrickle the holes, when they are full of corn, as the bar flides backwards and forwards.

The fimplicity of this flider at the bottom of the feed-box may be in fome refpects greater, than‘that of wooden and tin cylinders in the former machine; as this has but fix holes to meafure out the corn, and the other has twenty-four. But perhaps in other refpects lefs fo; as in this twelve brufhes are ufed, one on each fide of each of the fix holes; whereas there are only fix brufhes rub upon the tin cylinder in the former machine. And the reciprocating motion of this Îlider muft be quick, as it muft aét once every time the pe- riphery of the wheel of the carriage has pañled nine inches forward; which may not be fo eafy to execute as the cog-wheel, and unin- terrupted movement of the axis and cylinder in the preceding machine.

T have only to add, that the facility of adapting the holes to the dimenfions required in both thefe machines, and their not bruifing or breaking the grain in their operation of delivering it, as well 4s their not being encumbered with an additional hopper, which muft deliver the quantity of feed with great inaccuracy from the unequal fhakKing of the machine, adds much to the excellency and fimplicity of them both. And I hope will render more general the ufe of the

drill hufbandry invented by the ingenious Mr. Fuzz; who was on
