Properly to construct a water meadow is much more difficult than is commonlyimagined. It is no easy task to give an irregular surface that regular yet various figurewhich shall be fit for the overflowing of water. It is very necessary for the operator tohave just ideas of levels, lines, and angles ; a knowledge of superficial forms will not besufficient; accurate notions of solid geometry (obtained from theory or practice) areabsolutely necessary to put such a surface into the form proper for the reception ofwater, without the trouble and expense of doing much of the work twice over. ( Irrigation, §c.) 4438. As an example of irrigating a meadow from both sides of a rii<er, we take the following case from 684. Boswells treatise. From the upper part ofthe grounds, two main drains (fig. 684. a, a)are formed at right angles to the river, onerunning north, the other south, across themeadow, to within about six yards of the fenceditches which surround it (b) and are used fortail drains : by means of these fence ditchesthe water is discharged into the river. Awear erected across the river forces thewater into either of the main drains, whichis done by shutting the other wear clo» there is not water enough, or it is notconvenient to water both parts of the mea-dow at once, by shutting close one of thewears, the current is forced into that mainwhose wear is open, thence to be conveyedthrough the trenches over the panes, to waterthat side of the m
