the trenches before it would flow over the panes. H, H, H, H, H, H, H, II, H, 

 trench-drains to convey the water off from the panes. There mould be one 

 on each fide of every trench, unlefs a fence-ditch, or the river, can be ufed in- 

 fte.id. P, P, (luice drains, to convey the leaking of the water out of the mains D, 

 and F, L, I.., L, L, trenches taken out of the fmall mains, to convey the water 

 into the various parts of the rrveadow, which at the lower part increafes in width, 

 T, T, T, T, T, branch-trenches, taken out of the other trenches. N, N, N,N, 

 N, N, N, N, N, various gutters taken out of the ends of fome of the trenches, to 

 carry the water to the longeft corner of the panes, and fometimes taken out of 

 different parts of the trenches, to water fome little irregularities in the panes, which 

 without fuch afliflance would not have any water upon them, I, a matter or con- 

 fiderable drain, into which feveral others empty themfelves, and thence run into 

 the tail-drain. K, a fluice, erected at the end of the fmall main D, to force the 

 water in to the branch trench T, that being the higheft ground. M, the tail- 

 drain, which receives all the water from the other drains, and conveys it into the 

 river at O, the point where the water from the tail-drain runs into the river. 

 R, a fence ditch, being the bounds of the meadow on that fide, and ufedalfo as a 

 drain to convey the water into the tail-drain. 



Fig. 3. A, the head main, taken out of the river, forming an angle of about fixty 

 degrees. The defcent of the land permits the main to overflow it at B, the 

 point where the meadow can be watered, confcquently the place for the main 

 B B to be drawn, at right angles with the ftream, the whole breadth of the meadow 

 intended to be watered, excepting about five yardsat each end. C, D, two wears 

 creeled to turn the water either way ; or, when both are {hut, to keep it in its pro 

 per current. E, another wear for the purpofe of dividing the meadow into turns. 

 F, G, H, 1, K, L, A D, flukes to convey the water into, or flop it out of the 

 trenches, as found neceflary. M, N, two drain fluices. O, P,Q^ R, S, T, V, W, 

 bends to flop the water in thofe trenches which have the quickeft defcent. X,Y,Z, 

 a, b, c, d, e, f, g, h, i, k, gutters to carry the water to the ends of the panes, and 

 little irregular parts in the meadow. C C, the lowcfl part of the meadow, where 

 water is conveyed away. From the main B B, to the principal drain A B, the 

 meadow is watered regularly ; but betwixt that drain A B and the fmall main 

 A C, there is a great flat. To fill it up would be the regular method, fo that the 

 trenches taken out of the main B B fhould go down to the end of the meadow ; to 

 avoid that expenfe, the end of the main B B is continued down to the eaft fide of
