WATER-WORKES. 



third, commands the same River a mile 

 below, at the lowest part of my ground : 

 So, you see, that within the running of 

 two miles, I plant three sluces ; the maine 

 Silles being forty foote long. The reason 

 why I planted so many within the length 

 of two miles, was this : the river being 

 thirty foote broad, and ten-foote deepe, 

 my Trench-royall beeing but ten-foote 

 broad, and foure-foote deepe, it received 

 no more water then the breadth and 

 depth would give leave. 



Not-with-standing the quantity of wafer 

 my Trench-royall received, I did not find 

 the want of any in the maine-river ; which 

 caused me to raise those two other sluces : 

 grieving so commodious an Element, so 

 rich and substantiall, should fall into the 

 Bowels of the sea, with-out profit. I call 

 that a Trench-royall^ where part of the 

 maine-river is commanded by since into it. 

 I call that a counter-trench^ where part of 

 the river is stolne in by the rising of the 

 flood to the levell of the banke with-out 

 sluce. My topping or braving-trench is that 

 which hand-maides the maine-river (side by 

 side) unto the end of the worke. The 

 Winter and Summer-trenches^ bee those that
