Description of the Plates* 



tLATE I. 



By Plate 1, 1 have endeavoured to repre- 

 sent a meadow, which has no material 

 irregularity in its surface, but has one 

 gradual descent, in the same direction 

 with the current of the river or stream. 

 This meadow is supposed to be too high 

 to be floated from that part of the stream 

 which is nearest, and immediately oppo- 

 site to it ; and therefore, in order to gain 

 fall, or power, the water is taken out at a 

 higher part of the stream, and conveyed 

 by the conductor, marked C, into the 

 feeder, which has a flood-hatch placed in 

 the mouth of it, to admit or exclude the 



water
