MAY. 307 



1st, The great benefit to be derived from power 

 to take water from a river, or stream, or lake, &c. 

 will much depend on taking the first level from 

 the highest spot on the water to which the opera- 

 tor's property or farm extends. If he is a land- 

 lord, and has several farms on a stream, and some 

 out of lease, others in lease, he must either wait 

 till the leases are expired, or he must purchase of 

 his tenants liberty to run his grand carrier through 

 their farms (the property of the water retained to 

 himself) wherever the level may point out. 



2d, If the stream be any thing considerable, he 

 may probably find water-mills the greatest impedi- 

 ment to his project, whether his own, if leased, or 

 belonging to other landlords : he must make him- 

 self thoroughly acquainted with this circumstance, 

 or, after having been at considerable expences, he 

 may meet with a prohibition against taking" the 

 water, when he is just ready to open the sluices 

 and set it a-flowing. 



3d, If the river be the boundary of his property, 

 and his neighbour on the other side has an equal 

 right to the water with himself, he may be in the 

 same predicament, and a deed of sale, or transfer, 

 or permission, must be obtained before he begins, 

 not possibly in the power of the person to grant. 

 All this must be well understood before he com- 

 mences his operations. 



4th, If, in running his first and highest level, he 

 meet with a field or fields not his property, which 

 intervenes by elbowing into his estate, and cuts
