WILD GARDENING ON WALLS OR RUINS. 91 
A few seeds of the Cheddar Pink, for example, sown in a 
mossy or earthy chink, or even covered with a dust of fine 
soil, would soon take root, living for years in a dwarf and 
perfectly healthful state. The seedling roots vigorously into 
the chinks, and gets a hold which it rarely relaxes, A list of 
many of the plants which will grow on walls will be found 
among the selections near the end of the book. 
The Vellow Fumitory on wall (Corydalis lutea).
