In conclusion it is encouraging to know that the few 

 Corporations who have been in earnest are satisfied with 

 the results of their afforestation schemes. Liverpool, Leeds, 

 Birmingham, and Manchester have all done notable work, 

 an account of which may fittingly conclude the present 

 chapter. 



Liverpool. — The most important work of this kind is 

 probably the systematic afforestation that has been carried 

 out during recent years by the Liverpool Corporation on 

 their catchment areas at Vyrnwy and Eivington (12). 



The Vyrnwy gathering ground (13), with a total area

 areas drain into it, namely, the Eiver Vyrnwy area, 18,000

 the Vyrnwy area some disputed boundaries near the tops 

 of the watershed lines not yet settled. In the Cownwy and 

 Marchnant areas the Corporation have, to suit the con-

 extend beyond the catchment areas. The land, in great
