EMBANKING. 437 



of the improved salt-marsh, but not the cliadelphia family, 

 which come afterwards. 



Long before it is raised enough by successive deposits 

 of mud from high tides, it lets to the farmers of the con- 

 tiguous improvement for 5s. per acre ; some years since at 

 2s. 6 J. Broken as it is by holes and little creeks of water, 

 it lets, immediately after embanking, at from 20s. per 

 acre ; a few years ago to 40s. ; and 42s. at present. I 

 observed one or two pieces within Count Bentinck's 

 new bank, that were left in that rate \^:r cattle, but in 

 general they were under the plough, and the grass-fields 

 laid down after a course of tillage. 



The business of embanking to take in a new piece of 

 marsh, is done sometimes at the expense of the farmers, 

 who make the bank, to have tlic land rent-free for 21 years. 

 Adjoining to the Bentinck improvement, is a piece of 80 

 acres thus taken, but the bank very ill made, at no greater 

 expense than 40s. a rod. Those constru61ed by landlords, 

 were deficient in not having slope enough given towards 

 the wafer. Count Bentinck laid out his upon a scale 

 never practised liere before ; and his son, the present pos- 

 sessor, has far exceeded it. The former extends about 

 four miles, and added to his old estate, lOQO acres. The 

 base of the bank is about 50 feet. The slope to the sea, 

 36 feet, forming an angle, as 1 guess from my eye, of 25 

 or 30 degrees. The crown is four feet wide, and the 

 slope to the fields, 17 feet, in an angle, I guess, of 50 de- 

 grees; the slope to the sea, verv nicely turfed. I^iie first 

 expense of this bank was 4I. per rod, but a very high tide 

 coming before it was finislied, not only made several 

 breaches, but occasioned an additional heiglit and sJape to 

 be given to several parts, to bring it to the above dimen- 

 sions, all which made the gross expense about 5I. a rod. 

 The whole cost something above 500^!. X he expense of
