THE PINK FAMILY 67 



Remedy: A bare summer-fallow, with thorough cultivation, 

 will suppress it. Prof. G. E. Day, of the Ontario Agricultural 

 College, Guelph, states that the roots are fleshy and hard to kill 

 unless dragged right up to the surface of the soil. If there is a 

 little earth covering any part of them, they will continue to 

 grow and try to produce seed. When spudded below the surface, 

 they will grow again but do not produce seed that season. A 

 short rotation of crops will keep it in check. Discing bare stubble 

 will help prevent it from seeding late in the season. Thick 

 seeding with clovers will restrict it by smothering. Pastures 

 following a single cut of early clover should be trimmed with a 

 mower about the middle of August to prevent the maturing of 



ALLIED SPECIES : Several species that are found 

 growing as weeds have escaped from gardens. 



Dusty Miller (Lychnis coronaria (L.) Desr.) is a showy plant 

 with crimson flowers and white foliage. 



Ragged Robin (Lychnis Flos-cuculi L.) is occasionally met 

 about old gardens in the Maritime Provinces. It has a slender 

 stem and rose or pink flowers, the corolla divisions 4-cleft. 



Scarlet Lightning (Lychnis chalcedonica L.) is also some- 

 times found naturalized in localities where it has escaped from 

 cultivation. 



Red Campion (Lychnis dioica L.) is a coarse, hairy, some- 

 what viscous plant, quite common in some localities in the 

 eastern provinces where it has become naturalized, apparently 

 from cultivated forms. 



Drummond's Pink (Lychnis Drummondii Hook. Wnts.) is 

 characterized by narrow leaves, small pink flowers, and a stem 

 almost leafless above ; quite common in Manitoba. 



All weeds, as such, are pernicious, but some much more than others ; some do more 

 injury, and are more easily destroyed; some do less injury and are harder to kill; others 

 there are which have both these bad qualities.
