At Fig. i, in Plate XXII. A,A, reprefents the river running through lands. 

 B,B, two mains drawn at right angles with the river, one running north, the other 

 fouth, acrofs the meadow to within about fix yards of the fences. C, C, fence 

 ditches at the head of the meadow, ufed for tail-drains to convey the water that 

 runs over the way-panes, I, I, watered from the upper fide of the mains, B, B ; 

 by thefe fence-d itches the water is conveyed into the fide fence ditches, H, H, 

 to the tail-drains, or lower-fence ditches, G, G, and difcharged by them into 

 the river A again at K. D, a wear creeled acrofs the river to force the water 

 into either of the mains, B, B, which is done by fhutting the wear D clofe. L, 

 L, two wears erected at the mouth of each of the mains, B, B; their ufcs arc, 

 when the wear D is (hut clofe, and there is not water enough, or it is not con 

 venient to water both parts of the meadow at once, by (hutting clofe one of thefe 

 the. current is forced into that main whofe wear is open, thence to be conveyed 

 through the trenches over the panes, to water that fide of the meadow ; then by 

 fhutting that, and opening the other, the oppofite main, B, is filled, and by 

 means of the trenches that fide of the meadow is watered in the fame manner; and 

 laftly, by (hutting them both, and opening the wear D, the water flows in its ufu- 

 al courfe, and the land on both fides is laid dry. E, E, E, E, trenches taken out 

 of the mains B, B, to convey the water over. MMMMMMNM, which are 

 the panes or parts of the meadow that produce the grafs. F, F, are trench-drains 

 to draw off the water from the panes and convey it into the tail-drains. G, G, the 

 weft fences of the meadow, here ufed for tail-drains to convey the water into the 

 river. K, the place where they difcharge themfelves into the river. N, N, two drain 

 fluices, one at the lower end of each main, ufed when the wears, L, L, are either or 

 both of them mut clofe ; thefe drain fluices are opened to convey the leaking our 

 of the mains into the fence drains, H, H, to keep the land dry and healthy. 

 I, I, are the way- (or road-) panes, watered from the banks of the mains B, B, 

 the whole length of the mains. 



Fig. 2. A, the river. B, a wear erected acrofs the river. C, the head main ta 

 ken out of the river above the wear B. S, a wear erefted acrofs the main C, to 

 be kept clofe when the meadow is not watered. D, a fmaller main, taken out of 

 the head main C. E, E, E, E, bends made in thefmall mains, and trenches juft 

 below the places where the branch- trenches are taken out of them, to check the 

 water at thofe places, and force a proper quantity into branch trenches. G, G 

 G, G, G, G, bends made in thofe branch-trenches which have fo much defcent 

 that, were it not for thefe bends, the water would run down almoft to the end of
