190 TOWN PLANTING 



ations from alkali and other chemical works 

 are most disastrous in their effects on vegeta- 

 tion generally, the Sycamore, but particularly 

 the variegated leaved variety, is one of the 

 few trees that will grow satisfactorily. At 

 Bermondsey, Lambeth, and other equally 

 confined and smoky parts of London, the 

 Sycamore can be seen in a thriving condition, 

 and, what is equally valuable, it reproduces 

 itself freely from self-sown seed. In a dry, 

 confined corner near Camden Town, where 

 the sulphurous emanations from the railway 

 cause even the hardy Elder to wince and 

 seem unhappy, the Sycamore does well, and 

 seedlings grow with a rapidity that is quite 

 surprising. Few soils would seem to come 

 amiss to the Sycamore, for even on rubbish 

 heaps self-sown trees may be found in the 

 perfection of health and growing freely. In 

 Warrington, too (one of the most chemically 

 impure of town atmospheres), Sheffield, and 

 Liverpool, the Sycamore is a favourite tree 

 and planted extensively.
