Water at pleasure. Tliis conductor, (tr^ 

 will say, for the sake of illustration,) has 

 only four inches descent in its whole 

 length, but the stream in the same dis- 

 tance falls ten inches ; therefore six inches 

 of power are gained by means of the con- 

 ductor, which power, or fall, is abundantly 

 sufficient to cause the water to work well 

 upon the meadow. This mode of gain- 

 ing or reser%^ing descent is well worthy of 

 public attention, and, if generally adopt- 

 ed, would bring thousands of acres within 

 the fertilizing power of this practice, which 

 are now thought to be utterly beyond the 

 reach of the water. I have seen water 

 thus conducted for more than the dis- 

 tance of a mile, which lias afterwards 

 amply compensated for the expense of 

 the work. The feeder in this Plate is 

 cut along the higher part of the meadow, 

 and from it, at right angles, the floating- 



' gutters
