"12 foot above the level of your flream, and will go four times 

 *• round in one minute, and carry up about 1 20 hogfheads of v/a- 

 *' ter in an hour, with 12 or 18 inches penning or flopping of but 

 *' an ordinary current of water, which will water very well 30 or 

 [' 40 acres of land : for if your land be cold and clayey, too much 

 " water does it hurt ; and if it be light, warm, or fandy, a little 

 ** water does it much good. It is alfo to be obferved, that this mo- 

 " tion is conflant, and will lafl many years without repair, fo that 

 " it {land not flill, the one fide drying and waxing lighter than the

**-The view of this wheel we have in PL I. Fig. 2. aaaa iignify 

 ** the wheel ; b, the ciflern that receives the water ; cc, the trough 

 " flanding on treflels, that conveys the water from the ciflern to the 

 ** place you defire ; dy the hatch, or pen-flock that bays up the wa- 

 ** ter to a reafonable height, under v/hich the water drives the 

 *' wheel ; e, one of the floats prefented to your eye, apart from the 

 " wheel ; f, the open place that is to receive the water -, g, the 

 " open place out of which the water iffues ; hh, the two pins or 

 ** ledges riveted on to the forefide of the float, and wherewith you 

 " are to fix the float to the two rings of the wheel. Thefe, or 

 " fuch like wheels are much ufed in Spain, Italy, and France, and 

 " are efleemed the moft eafy and advantageous way of raifing water 

 " in great quantity, to any height within the diameter of the wheel, 

 " where there is any current of water, to continue it in motion, 

 " which a fmall flream will do. 



" How many acres of land lie on the declining fides of hills, by 

 " the fides of rivers, in many places where the water cannot be 

 " brought unto it by any ordinary way .? yet by this wheel placed in 

 *' the river, may the land be continually watered fo far as is under 

 *' the level of the water when raided." 



Mr. Worlidge proceeds to obferve, that there are many large and 

 flat pieces of land, bordering upon rivers, in which the Perfian wheel 

 cannot be placed without trefpafTing upon the oppofite neighbour, 

 &c. but where wind-mills may be ereded on the higheft part of 

 the land you intend to overflow. Though this place may bq at 

 fome diflance from the river, the water may be eafily condudred 

 thereto by an open or fubterraneous paflTage from the river. 



Such miUs are experienced to be of great lervice in draining of 



fens and marfhes, and may likewife be ufed to great advantage in
