" and that with very great expedition, and very little extraordinary 

 " charge, expence, or hazard. 



" Firft, make a frame of timber, of about two or three inches 

 " fquare, the breadth of the frame about two foot, the height 

 *' about eighteen inches, the length about four foot, more or lefs as 

 " you pleafe, as at u u u u, ^fig. i. Plate IV. Place this frame on 

 " two pair of ordinary wbeels, like plough-wheels. The axle-tree 

 " of the two foremofl; wheels is to lock on either fide, as doth the 

 " fore axle-tree of a waggon, for reafons hereafter (hewn. The 

 *' hindermoft axle-tree, being of iron, and fquare in the middle, 

 ** muli be fixed to the center of the wheels, that the axis and wheels 

 " may move together : then, about the middle of the frame, in the 

 *' bottom, let there be fixed an iron inftrument, or of wood poijited 

 " with iron, like unto a coulter, inade a little fpreading at the bot- 

 ** torn, in the nature of a fliare, made to pafs through two mortifes 

 " on the top for its greater flrength ; and made ahb to be wedged 

 ** higher or lower, according as you will have your furrow in depth, 

 "as at ; the ufe whereof is only to make the furrow : fo that 

 '' you muft make the point thereof of breadth only to move the 

 " earth, and caft it, or force it, on either fide, that the corn may 

 " fall to the bottom of the furrow. Then, over this fliare, or 

 " coulter, a little behind it, may a wooden pipe be made, to come 

 " from the top of the frame to the lower end of the (hare, taper- 

 *' ing downward, as at p, and as near as you can to the (hare : to 

 " deliver the corn immediately, as the ground is opened, and be- 

 " fore any earth falls in ; that what earth does afterwards fall in, 

 •* may fall on the corn. This pipe is to proceed out of a large 

 " hopper fixed on the top of the frame, that may contain about a 

 " bufhel, as at q: but fo that the corn may gradually defcend, ac- 

 " cording to the quantity you intend to beftow on an acre. At 

 " the very neck of the hopper, underneath, in a fquare hollow 

 " thereof, muft be fitted in the edge of a wheel of wood, about 

 " half an inch thick, and proportioned to the cavity of the neck, 

 *• as behind the letter r. The wheel need not be above two or 

 ** inches diameter, and fixed on an axis extending from one fide of 

 " the frame, to the other : on which axis is alfo to be another 

 " wheel, with an edge on the circumference thereof, like the wheel 

 " of a fpit or jack, as at r, which muft anfvver to another wheel 

 " of the like nature and form, fixed on the axis of the hindermoft 

 " of the wheels, as at s : then fit a line, (of filk is beft,) becaufe
