third stick, the water will go to the place desired. The aboveis so simple, that it will be easily understood by tire figure, with-out any farther explanation.
Plate II.
In this plate, I have attempted to delineate a regular formedflat water meadow, on the position of the haugh-land in Scot-land , as mentioned at page 135. This piece of land is sup-posed to be in ridges, of from 10 to 12 yards, designed andformed so by the plough, or left so by accident, with a sufficientdescent down it; but from the cause mentioned at page 135,it is supposed necessary to take the water out of the river a-bove the meadow, as far up as the water might be raised witha low wear of stones, high enough to go to the most elevatedpart of the meadow. For this purpose, the place marked A, isfound high enough, which is a rough stone wear of about 2 feethigh, and is supposed to divert from the river all its water intothe conductor 15, in ordinary times. The conductor B is car-ried along the edge of a brae, to keep up the water to the level,until it enters the meadow, when it is laid out into a feeder, witha bank on the lowest side, to keep the water above the surfaceof the ground, so as to throw it with the more force into thefloating gutters : The bank (and all the feeder banks) is describ-ed with a double line, with notches through it, for distribut-ing the water: The distance betwixt the notches is not fixed,but variable at pleasure, and may be in one place one year, anddifferent in another. The feeders are marked with a C in eachbranch, and each main drain is marked with a D, being 2 in num-ber. The places, marked H, are hatches or sluices, for remov-ing the water from one part of the meadow to the other. Theplaces, marked with I, are small apertures for letting off any wa-ter that may remain in the feeder after the water is removed.The places marked with s, are stops for obstructing the water,Md forcing it over the sides of the feeder, or out at the notches.The small dots in the floating gutters, are stops also for the samepurpose.
Ibis meadow is divided into four divisions, which are marked2, 3, 4. The river is supposed usually to afford water enoughlor two of these divisions at a time; and in floods, for all four ofthem: But in spring, when the water turns scarcer, or too littletor two divisions, then one of them may be done at a time.
I have attempted to show -the water upon, or in, the feeder ofthe first and second divisions. The hatch is supposed to be liftedU P, in the mouth of the feeder that waters divisions 1st and 2d ;»nd the other hatch down, that is, in the mouth of the feeder that"aters divisions 3d and 4th. When this last hatch is lifted up,■} n( l the other let down, it is supposed that the fall in this middleeeder is great enough to draw the water in the head feeder be-
