NOTES ON THE BOTANY OF WIDNES. 297 
To sum up. Undoubtedly in years past the chemicals 
have had a most deleterious effect on the trees and hedges. 
There are, however, unmistakable signs of recovery. 
Hedges are being planted again in the Farnworth district, 
notably on the Sheffield and Midland Railway (and a 
railway company usually makes very sure before incurring 
expense). Blackberries, and even young oaks, are © 
springing up. The great drawback to vegetation is the 
unchecked violence of the gales. This is a direct result 
of the destruction of the trees. Houses only intensify the 
evil by collecting the wind into eddies and draughts. 
Some trees, a kind of balsam poplar and the golden elder, 
are planted and flourish fairly, and we may improve in 
this respect.
