blooming, take them up, divide them, every piece with a 

 root will make a plant, and set them in a damp, sheltered 

 spot in the garden, to make plants for the next autumn. 

 Put away the frame and sash in a dry place, for fu- 

 ture use. 



A good plan is to have the beds laid in masonry; then 

 they are permanent, and require only to be filled in with 

 compost and planted. 



A wooden frame will, however, with care, last from three 

 to five years. 



The best varieties to plant are, 



The SINGLE ENGLISH. This is very early and fragrant, 

 and an abundant bloomer. 



The DOUBLE ENGLISH. Dark blue. 



The DOUBLE ENGLISH WHITE is pretty, but forces 

 badly, usually having a green centre. 



The DOUBLE LIGHT BLUE, called the Neapolitan Violet. 



It is not well to mix the varieties in the same bed, 

 as they come to perfection at different times. 



THE POLYANTHUS. 



This variety of the Primrose, commonly called Cowslip, 

 may be bloomed in the same way as violets.
