powerful than on other forts of lands, Someftrong adhefive four wet lands, fuch 

 as arc common in the vicinity of large rivers, are alfo capable of being improved 

 by watering; but the beneficial effects are not in thefe cafes fo foon produced as on 

 thofe of the above kind, nor is the procefs fo advantageous to the farmer, on ac. 

 count of the very heavy expenfe to which he mud, in many cafes, be put by pre 

 vious draining. Such lands as contain coarfe vegetable productions, fuch as heath, 

 ling, or rumes, may alfo be greatly improved in this way. There is another circum-* 

 fiance in regard to the different foils that may be benefited by irrigation,^ hich is, 

 that the more tenacious the foil is, the greater the command of water ought to be. 



A flream capable of watering fifteen or twenty acres of light dry land, would be 

 found to be beneficial in but a fmall degree if applied to watering half the fame 

 extent of cold clay foils, fuch as in their natural ftate abound with rufhes. All 

 foils of the laft fort require a confiderable body of water for the purpofe of float 

 ing them, in order to produce much effect. If this cannot therefore be procured, 

 fuch means of improvement will feldom anfwer the farmer s expectation, or turn 

 out to much account. 



Thofe grounds which admit of being benefited in this way with the mofl fuccefs 



Way -pane. The ftrip of land left for cartage along the fide of the main, being watered from the 

 banks of the main, and drained by a parallel ditch. 



Bend. A ftoppage made in various parts of thofe trenches which have a too quick defcent,inorJer 

 to check the water and force it out of the trench. This is done by having fmall dams of the natural 

 fward at proper places, arid cutting a fod out of them wedge-ways, fo as to ftop the current and give a. 

 more equal diftribution to the water 



Gutter. A fmall groove cut from the tails of the trenches occafionally, to diftribute the water to 

 the utmoft extent of the panes more equally than by the regular works. 



Catch-Drain. An occafional ditch which is fometimes cut to carry the fame water into a fecomi 

 main, for the purpofe of irrigating a lower meadow, or pane, with the fame water which has been ufed. 



Pond. Is applied to any fpot of ftagnant water which is left on the ground in the procefs of irriga 

 tion. 



Turn of Water. As much as can be diftributed at a fingle operation by the management of th 

 hatches within the reach of the labourers employed, and as the ftream will fupport. 



Head of the Meadow. That part into which the main firft enters. 



Tail. That part where the water laft pafies cffby the tail-drain into the natural river,, or fewer ; OP 

 where that fewer itfelf leaves the meadow. 



Upper Side of a Main. That which, when made at nearly right angles to the river, fronts the point 

 it which the river enters. 



Lower Side. The reverfe of the above. 



Upper Pane. That which lies above the main, if fuch be left*
