A. D. 1788. 179 



By defire of the committee of the privy council for trade, the in- 

 fpedor-general of imports and exports laid before them 



A coviparative view of the produce imported into Great Britain from the 

 Briti/h Wefl-lndia iflands and fettlements in the years 1787 and 1788 *. 



The value is here rated at custom-house valuation. The real selling prices are considerably higher. 



A navigable communication 



was made between Donnington-wood 



canal and the River Severn in Shrop-ihire. The chief reafon of men- 

 tioning it, is that the barges on it are raifed to 455 feet of perpendi- 

 cular afcent, not by a great number of locks, but by means of three in- 

 clined planes, whereof 



the upper one has 1 22 feet of ascent with 960 feet in length, 

 the middle one 126 1758, 



and the lower one 207 QOO. 



Upon thefe planes the vefTels are towed up by the power of fire engines ; 

 and this method is found more economical than the elevation by locks.
