Valeriana. Valerian, 

 Tripteris, Phu, calcitrapa. 



Viola. Violet. 

 Calcarata,odorata, and thirty-eight other species. 



This sweet little flower is an universal favourite. The 

 odorata and its varieties are most valued ; but they cannot 

 be had in perfection unless a good deal of pains is bestowed 

 on them. Slugs are very destructive to the violet, devour- 

 ing the flowers as much before as after they are in bloom. 

 Where the flowers are in much request, beds are made on 

 purpose for them, composed of a layer of coal-ashes on the 

 bottom, covered with a compost of peat-earth, loam, rotted 

 cow-dung, and sand ten inches thick. On this young 

 runners are planted, six inches apart, in July, carefully 

 attended ; and, when the cold of autumn sets in, they are 

 covered with a frame and lights, and defended from the 

 frost throughout the winter. Violets should be potted in 

 August for forcing, which is most successfully done in a 

 mild hot-bed. The double Neapolitan is the best for 

 forcing.
