Fig. 2. This figure is designed to represent a floated meadowformed in a narrow valley by the aid of two small streams, A i,and A 2.
Here the stream, by being dammed up at B i, is found toforce the water into F i, (without having recourse to fetchingthe water from a distance, as in some of the preceding plates),which floats the upper part of the meadow, and also the edge ofa brae with the gutter E, and waters the space betwixt it andthe drain d 1, and the gutter G, where it is a kind of catch-work.The water that runs off the upper part of the meadow’, and offthe brae, passes down the drain d 1, and fills the feeder againfor floating the lower division at F 3.
The middle division is watered by F 2, which receives theconflux of the small stream A 2, by its being obstructed by thedam B 2. There is an aperture at O, for letting the waste wa-ter out of d 1, down d2, when the first two divisions are laid dry.
N.B. By using a part of the water twice, the whole meadowis watered at one time ; and, by the simple hatches in the mouthsof the feeders, it may be all laid dry, and the water pushed downits wonted channel, by slackening the dams a little ; which mayeasily be done, if they are put in with stakes and sods ; and ifcovered with stones, the water may flow over the top of them.
This meadow is supposed to be made on land of the first orsecond class, mentioned in the Chapter.
Plate VII.
Is designed to represent the different kinds of catch-work appli-cable to the North of Scotland , or any hilly country.
Fig. 1 . represents a few ridges which have formerly beenploughed, lying betw’ixt a hollow at the foot of a hill, and asmall stream of w’ater, marked A.
In floating this piece, it is found that the water can only betaken out into the feeder F, at tire dam B. The stream of wa-ter being but small, with a great descent on the ridges ; in or-der to make the most of the water, the drains are taken up atC G (which signifies catch-gutter), and are angled across thesides of the ridges, until they become floating-gutters again. Alarge ditch is carried round the meadow,- up to D, to keep offthe sink of the hill, and also to drain the hollow. As the feederF is upon a level ; when the water is quite scarce, one or moreof the beds may be floated at a time, by stopping up the mouthsof the other gutters with a sod or two, or a bit of board. Thissimple figure will be immediately understood, by looking at theplate.
Fig. 2. In this figure, floating is represented on the side of asloping brae. The feeder F is taken out of a small stream thathas a great declivity, by means of the dam placed in it at D.This feeder is carried along the face of the brae, diagonally, un-
