dead level, and at every three or four hundred 

 yards, staking it out doubly, one stake on the dead 

 level, and another near it, descending from the 

 dead level, so many inches as an allowance to give 

 the water a current ; two inches in a mile will move 

 it, but twelve to twenty should be allowed, in order 

 that the current may be sufficient. 



7th, Roads need not be any interruption, as 

 they may be passed in a manner hereafter explained; 

 but farm-houses, yards, gardens, cottages, &c. 

 may intervene ; and if they do, a much greater 

 descent per mile must be allowed, that such inter- 

 ruptions may not be quite suddenly, but gradually 

 provided for ; as the former occasions inconveni- 

 ences. 



8th, In this manner let him proceed to the ex- 

 tent f his property, leaving stakes at all his sta- 

 tions, so firm in the ground, that they cannot be 

 removed. 



Qth, If both sides the stream be his own farm 

 or property, let him go back whence he started 

 at his highest spot, and do exactly the same on the 

 other side of the vale, staking out his level there also. 



10th, Having proceeded thus far, let him view, 

 and carefully examine all the land on both sides 

 the river below his lines of levelling, for he has the 

 power of watering all or any part of it, if the stream 

 be sufficient. The breadth will depend on the 

 degree of the declivity between his first and last 

 station ; and on the diverging and fall of the 

 higher grounds or hills ; but in every case he will 

 find a vastly greater quantity of land than he had 



any
