An encyclopædia of agriculture [electronic resource] : comprising the theory and practice of the valuation, transfer, laying out, improvement, and management of landed property, and the cultivation and economy of the animal and vegetable productions of agriculture, including all the latest improvements, a general history of agriculture in all countries, and a statistical view of its present state, with suggestions for its future progress in the British Isles. Agriculture. Book IV. GATES APPROPRIATE TO AGRICULTURE. 503 3094. In Parker's unproved swing gate, the diagonal bar rising from the lower part of the heel of the gate meets the middle of the rail, and the two upright bars are placed at proper distances between the middle and the head of the gate : 503 |â] these cross bars must, he thinks, i£| â âp, assist very much in keeping the gate together ; but what is most to be guarded against is its sink- ing at the head, to prevent which this gate is, he says, well con. trived. 3095.

When the head sinks, it is raised by the simple opera- tion of applying a larger washer between the key-wedge, which retains the hook of the upper part of the heel (a), and the hang- ing-post. The fastening latch is protected from the rubbing of cattle by a recess in the falling-post (b). Gates of this description are generally made in Scotland of pine or fir timber, or what is called foreign plank or deal. Mr. Menteath has the good fortune to possess on his own estates extensive plantations of pine planted by himself, and already affording an ample supply for gates and other purposes. We have already adverted to his mode of rendering this timber more durable by steeping it in lime-water; the same process will also render it less liable to warp when applied to the construction of gates.
