THE DAWN OF SPRING 



crevices which are bare. In rock walls "planting" in March 

 the ordinary sense is impossible, and one could hardly I0-3I 

 expect a plant that had so insecure a hold to thrive. 

 But with a good squeeze in, and a handful of moist 

 earth pressed after them, they manage to retain their 

 place, and soon anchor themselves securely with their 

 own roots. One odd bit so thrust in developed in such 

 an astonishing way on my wall, that it attracted the 

 attention of a pair of wagtails, who regarded it as 

 splendid cover. Any way, they found a comfortable 

 ledge under its long streamers, built a nest, and reared 

 a brood. Some rock plants are not easily propagated 

 by division, because the growth (and it may form a 

 considerable mass) is found to depend from one long 

 tough stem. Cuttings or seeds must be resorted to in 

 these cases.
