List of Patents for New Inventions. 317 



arise from this navigation are not merely local :— The Messrs. 

 Pickfords lately sent boats from Manchester, and instead of their 

 passing from the Grand Junction to Brentford, and there being 

 unloaded, and the goods re-embarked in other vessels for Dept- 

 ford they went direct bv the canal to Limehouse, and crossed 

 over' without anv delay; whereby not only time but a heavy ex- 

 pense, with probable loss and damage, were saved to the pro- 

 prietors. The dock too at Limehouse, being calculated to re- 

 ceive ships of considerable burthen, admits colliers, which dis- 

 charge their cargoes upon the wharfs, or into canal barges : and 

 thus the plunder and waste of coal, which so notoriously take 

 place in the Pool, are avoided, and many of those criminal acts, 

 the list of which heretofore has been frightful, are prevented.
