flows to the other fide ; and from thence 

 it is again by very narrow channels car- 

 ried to all the places where it feems ne- 

 celTary. To raife the water the higher, and 

 in order to fpread it more, there are high 

 dykes built near the fprings, between which 

 the water rifes till it is fo high as to run 

 down where the people want it. Indus- 

 try and ingenuity went further : when a 

 brook runs in a wood, with a dire<flion not 

 towards the meadow, and it has been found 

 by levelling, and taking an exad furvey of 

 the land between the meadow and the ri- 

 vulet, that the latter can be condudled 

 towards the former; a dyke is made, 

 which hems the courfe of the brook, 

 and the water is led round the meadow 

 over many hills, fometimes for the fpace of 

 an Englijh mile and further, partly acrofs 

 vallies in wooden pipes, till at laft it is 

 brought where it is wanted, and where 

 it can be fpread as above-mentioned. One 

 that has not feen it himfelf, cannot believe 

 how great a quantity of grafs there is in 

 fuch meadows, efpecially near the little 

 channels ; whilft others, which have not 

 been thus managed look wretchedly. The 

 meadows commonly lie in the vallies, and 

 one or more of their fides have a declivity. 

 The water can therefore eafily be brought to
