give it no more fall than necessary to bring the 

 water in a very gentle current. The stream is to be 

 made to overflow out of this carrier-trench all the 

 way it runs: the trench must be made gradually 

 smaller to the end, as the body of water it brings 

 lessens as it advances. 



I would advise the proprietor to see the expe- 

 rience of a year or two, watering with no further 

 expence than I have described (which is evidently 

 too trifling to be an object). If he find the effect 

 great, as in all probability he will, I should then 

 advise his levelling the spaces aver which he throws 

 the water, to that exactness which is necessary for 

 mowing ground : this, in many mountains, is the 

 most expensive part of the business ; for rains 

 which drive down their sides, in almost universal 

 torrents, work thousand* of little channels round 

 the tufts of heath, that are so deep and sharp, as 

 every sportsman knows, who has been tired with 

 walking, or rather tumbling over them : these 

 must all be levelled, and the. water let gently over, 

 which will soon cover them with grasses, and other 

 beneficial plants. The heath lives in its own acid 

 water, that stagnates in the moss and peat, as in a 

 dish, but will die away by being hooded in tlic 

 manner I have described. The progress of the 

 work will naturally arise from success ; if the pro- 

 prietor be attentive, he will find his success so great 

 and obvious, as to be induced to go into the busi- 

 ness with the utmost spirit. He will then level all
