ARTERIAL DRAINAGE. 153 



measures of drainage, not only along the Lough Corrib 

 district, but in the various other adjacent drainage dis- 

 tricts of Oranhill, Dunkellin, Lavally, Turloughmore, 

 Monivea, Dunmore, Shrule, Kilmaine, Lough Mask, 

 and river Robe." 



The advantages of the drainage, increase of water- 

 power, and connexion of Lough Corrib with the sea 

 for purposes of navigation, cannot be over-estimated. 

 The lowering of the level of Lough Mask, and the con- 

 sequent drainage of the adjoining country and the basin 

 of the river Robe, are also matters of the highest im- 

 portance ; but the extension of the navigation between 

 Lough Corrib and Lough Mask, by means of locks and 

 a canal cut through the solid limestone rock, however 

 desirable, will, I fear, be attained only at a cost dis- 

 proportioned to the ultimate advantage. The naviga- 

 tion for steamers must stop at Cong, at the head of 

 Lough Corrib ; and the distance to this point from the 

 surrounding country, including both sides of Lough 

 Mask, is not great. 



The peace and good order of the country have been 

 greatly promoted by the execution of these works. The 

 system of task-work introduced by them, with its stimu- 

 lus to energetic labour, the regular cash payments, and 

 the evident utility of the works, have all enlisted the 

 confidence of the people. During the excitement of 

 last year, the regular employment afforded by them is 

 understood to have been the means of preserving the 

 peace of many districts, besides lessening the tempta- 

 tion to crime.
