wear, it will here be observed, is entirely- 

 free from water, or empty ; therefore the 

 returning water is drawn off the meadow 

 by that depth of the bed of the river, added 

 to the descent which is found in the dis- 

 tance bet;ween the wear and the mouth of 

 the master-drain. The hatches, in the 

 mouths of F. 2, F. 3, are shut, and no wa- 

 ter, of course, is upon that part of the mea- 

 dow which they are made to float ; when, 

 however, that part which is supplied by 

 P. 1, has had the water a sufficient time, 

 its hatch will be let do^vn, and these two 

 opened ; for the stream will afford water 

 enough for F. 2 and F. 3, at one turn, as 

 they both are not required to supply a 

 greater extent of floating-gutters than F. 1 

 supplied. Thus, in this meadow, the 

 process of floating may conveniently be 

 alternate through the whole winter.
