408 CANAL BETWEEN THE 



vigate thofc of 100, or upwards, built and ringed on 

 a proper conftrucl ion. Ships paffing thii nghc 



to be built on the fame plan with thole employed by 

 the Dutch, Hamburghers, Dantzi< ;id other 



towns on the Baltic ; that is, long and flat bottomed 

 with lee-boards. All veflels or lighters proper for 

 navigating large canals, fhould befitted out and rig- 

 ged wi;h one mad, either as a (loop or galliot ; having 

 on yards aloft, they can take no wind-hold, fo that 

 they can eafily pals the canal, when a fquare n 

 fhip could not attempt it, befides the detriment done 

 to the locks and banks by high rigged veflels. 



There are veflels at prnent in the London trade, 

 from Lcith, that carry 130 tons, drawing only 

 feet water, and a fmall alteration in this model 

 will bring them to feven feet; confequently, when 

 the canal is completed, veflels of that burden 

 trade from the Clyde to the Baltic, Holland, and 

 all parts of Great Britain, without unloading at the 

 entrance of the canal, or any impediment what- 

 ever, except from occafional frofts in the winter, 

 and droughts in the fummer, to which all inland 

 navigations, whether natural or artificial are lub- 

 jeft. 



Canals, unlels frequently cleaned, are apt to fill up 

 in certain parts, and though the above-mentioned 

 cut was originally feven feet, no vclFc! drawing 

 above fix feet and a half can navigate on it, unlefs 

 the practice of (hipping in fliallow bar harbours be 

 adopted. As mod veflels draw more water in the 

 flem than in the bow part of the (hip, they are 

 med on an even keel, till they have patted the 

 ih allows, and by this method, half a foot water may 

 be gained. 



Bufles, and other unavoidable (harp-botto 

 vrflels belonging to the Clyde, may alfo pafs the 

 canal by means of lighters, the expence of which 

 cannot be great, nor would any additional tonnage 

 be charged.
