branches, to suit the position of the land, the ridges lying in twqdirections, and being, of different sizes. Division 4th, is the low-est corner of the meadow, and is found low enough to convertthe drain marked D, belonging to No. 2, into a catch-feedcr atC F, (which signifies catch feeder.) Division 2d, being ratherlarger than the 4th, it gives a small additional quantity of water,■which makes up a little for the quality, as should always be tlu>case where the water is used a second time. It is supposed, thatin ordinary times the river gives water for F i, or the doublefeeder F2, at a time, and, in floods, for all of them together.When the water is very low, one division may be done at a time.By having a meadow in divisions this way, the process of float-ing may be alternate throughout the whole winter or floatingseason.

N. B. From the height of the land on the back side, it is sup-posed that the conductor marked C must be taken out of the ri-ver at A; and that, from the height to which the water is want-ed to be raised, a frame of hatches is wanted at B, which are tobe taken out and put in at pleasure, that the water may be let.down its channel in the summer. As, by keeping it up, it mightoccasion damage to the adjacent lands in heavy rains, the hatchmarked H in the conductor, is placed at a considerable distanceflora the river; as far so, as to prevent the water from getting inbehind it in summer floods, when they overflow the banks. Thismust, alwaj's be attended to on rapid streams.

Cj* If the feeder becomes drv when the water goes down thechannel, the hatches at the mouths of the feeder will supersedethe necessity of one in the conductor. The 3 principal drains ofthis meadow are marked with a D. II, at the mouths of thefeeders, signifies hatches.

N. B. This meadow is supposed to be irrigated, in its naturalstate, just as the plough left the ridges.

This plan is quite easy to be understood on inspection, withoutany farther directions.

This, and the former plate, is designed to answer the first classcf land, mentioned in the Chapter.

Plate IV.

This 4th plate is supposed to represent a piece of water-mea-dow, made from a piece of haugh land, lying between a streammarked B, for driving a mill, and the river from which the saidwater is taken out, by means of a rough-built wear of stones atA> which lets as much water pass over it as goes down the mill-stream perhaps:—(These kind of -wears are called Intakes in theNorth of Scotland , and the mill-stream is called the Mill-Lead.)In this case, it is supposed that the intake, as it is called, is madea little closer, and the mill-lead serves for a main feeder. Thepiece marked E, is too high for the water, and cannot be float-
