and enable any one who may be desirous of erecting a wire fence 

 or trellis to do so, with the assistance of a mason and black- 

 smith, at a very moderate expense. The wire used is known as 

 No. 3^. It is about a quarter of an inch in diameter, and is put 

 up in large coils. Each wire measures from 1 15 to 120 feet in 

 length. The main upright posts, (fii^. 6 a a,) are of iron l| inch 

 square, and from 5 J to 6 feet high, with holes six or seven inches 

 apart for receiving the small screws and nuts to which the wires 

 are attached, in the way shewn at No. 5. At the opposite end 

 the wire is secured by being bent a little at the point, and having 

 a small wedge driven over it in each of the holes of the upright. 

 Both these main posts are ih feet above the level of the ground, 

 and are fixed beneath the surface in large rough blocks of stone, 

 d e, with iron wedges, which are more convenient, and answer the 

 purpose quite as well as if they were run in with lead. The stay 

 bar is round, and 1^ inch in diameter. It varies in length accord- 

 ing to the inclination of the ground, but when the latter is nearly 

 level it is about 7 feet long. The upper end is flattened, and be- 

 velled, so as to square with the upright, to which it is fixed by 

 means of a screw at /. The lower end is only a little bent that 

 it may fit into a somewhat smaller block of stone, than the one 

 at d. The connecting bar, c, is square or round, and need not 

 exceed an inch in either case. It will also vary in length, accord- 

 ing to circumstances. On a nearly level surface it must be about 

 5 feet long, and have an eye at each end large enough for the 

 end of the post and stay to go through. In addition to this, 

 there are uprights of one-inch flat bar by half an inch in thick- 

 ness fixed in stone, at 30 or 40 feet apart, or even nearer if 

 necessary, for the purpose of stiffening the treUis. 



" In the erection of this kind of trellis it is requisite to have 

 an instrument for drawing the wires like the one represented at 

 fig. 4, to the scale of an inch to a foot, which may be made 

 without much difficulty. The one I have sketched was con- 

 structed by our own blacksmith, and is a very efficient contriv- 

 ance for the purpose. After the stones are bored and set in their 

 places, with the earth firmly rammed around them, the next thing 

 to be done is to fix the main post, a, and wedge it tight. It 

 ought to lean about an inch back from the perpendicular, to allow 

 for its giving a little when the whole strain of the wires comes 

 upon it, which will bring it upright. The connecting bar, c, is 

 then slipped down over it, while the lower end of the stay bar, 6, 

 is put through the other eye and into the stone e, and the upper 

 end screwed to the main post at /. The triangle from which the 

 wires are to be stretched is then complete. A similar triangle 

 must be made at the opposite end, and against the main post of 

 which, p, the instrument No. 4, above noticed, is to be placed for 

 the purpose of drawing the wire. This is done with great facility 

 by means of a double piece of rope-yarn twisted several times
