1805.] On Farming in the Northern Counties, 229 will, when thrown open nearly to the line of its highest eleya- tion, return to the falling-post, with'a velocity Sufßicient to re- Sist a moderately Strong wind. This velocity will be either in- creased or diminished, accordingly as the upper hook declines more or less, from a position perpendicular to the lower hook. In order to adapt the thimbles to these hooks;--as the lower hook is one inch and a half farther from the gateway than tbe upper hook, the lower thimble must have its eye an inch and a half farther from the heel of the gate than the eye ofthe vpper thimble, in order that the Bars of the gate may be in a horizontal position when it is Shut. And, as the upper heok projects half an inch less from the hanging-post than 0. Wa hook, the upper thimble:Should be fixed half an inch nearer the Forer Side of the heel of the gate, than the lower thimble, in order that the gate may be in a perpendicular position when Shut. Ifthe thimbles have straps embracing the heel of the gate, and proceeding a few inches along each zide of the bot- tom and top bars, and if they are fixed to the heel bars and braces, by means of iron pins and Serew nuts, great firmness wil] be given to the gate at those two points, which are those that Suffer the greatest Strains." WAISTELL.

THIS is to certify, that I have constructed Several field gates, sfter Mr. Waistell's plan. I approve of them beyond Boe after any other plan, and find them to answer well in use. Allthe field gates 1 have had made, these three or four years, have been after his plan. They take less timber, are less expensive, and are Stronger and more durable than thioze made in the common way.
