1904.] Afforestation of Catchment Areas. 



471 



most of the land of catchment areas would seriously limit the 

 cultivation of deciduous trees, with the exception of the larch. 



In the case of Liverpool, Mr. Joseph Parry, Chief Engineer 

 to the Liverpool Corporation Waterworks, gave some particulars 

 to the Committee as to the steps taken towards planting the 

 catchment area round Lake Vyrnwy. The direct drainage 

 area is 18,500 acres, of which 1,000 acres have an altitude of 

 from 825-1,000 ft. ; 2,000 acres between 1,000 ft. and 1,250 ft. ; 

 3,600 acres between 1,250 ft. and 1,500 ft. ; and 8,000 acres 

 between 1,500 ft. and 1,750 ft., the rest of the drainage area 

 being at a still higher elevation. The trees planted include 

 larch, Scots pine, Douglas fir, Spruce fir, Corsican pine, Wey- 

 mouth pine, beech, sycamore, ash and alder, the plantations 

 being supplied from the nurseries established on the estate by 

 the Corporation. The total expenditure on the plantations has 

 been at the rate of about ,£200 per annum, while in the five 

 years up to 1902 a total of about £300 had been spent on the 

 nurseries.

The Llandudno Urban District Council state that they have 

 considered the question, and have decided not to plant trees on 

 account of the bleakness and inaccessibility of the position, and 

 because most of the area above the lake levels is considered 

 unsuitable for the purpose.
