 Bridgewatery promoted by my Lord Gower, 

 and carried on by fablcription, to join the 

 ports of Ht^// and Liverpool, is carried 

 acrofs the kingdom, without any very ma- 

 terial interruption, except at Harecajlle i 

 but there it follows a valley, which, ccn^^ 

 trary to moft, terminates againft hills, with- 

 out any winding around them ; fo that the 

 navigation muft either be here flopped, 

 and a land carriao-e, like the American ones, 

 at the falls in their rivers, be the confe- 

 quence, or the range of hills which faced 

 them pierced through : The attempt was 

 an immenfe one 5 but it is made, and will 

 undoubtedly fucceed. 



The tunnel, in the Duke o( Bridge-ivaters 

 navigation, is of a fmall breadth, as it is 

 the termination of the canal, and boats 

 made on puipofe for entering it ; but Hare- 

 cajik being almoft in the center of a navi- 

 gation of an hundred miles, a fubterrane 

 muft of necefTity be fpacious enough to ad- 

 mit all the traffic of the canal, pafling and 

 reoaffing, or it would be ufelefs. The ca- 

 nal is therefore carried under-ground in its 

 common breadth and depth ; it is twelve 

 iect v/idc, and nine high ; and will extend 

 under an high range of country above a 



mile
