may be shaken out so as to get rid of all the soil, and the roots 

 allowed to dry ; but except ouce in two or three years, in 

 order to remove offsets, and to limit the size of the pots, this 

 violence need not be done ; indeed, they will always bloom 

 better the second year after replanting than the first. By 

 crossing hundreds of really beautiful varieties, and thousands 

 good for nothing, have been raised. Those who desire to 

 cultivate them should see collections in bloom, and select 

 from them only ; for, although twenty handsome hybrids 

 might be named, there are inferior ones to be met with under 

 the same titles. The seed may be sown in pots in the stove 

 or hotbed, and the young plants pricked out an inch apart as 

 soon as possible, unless they have been sown at this distance, 

 and then kept growing the first season. After this change 

 the pots for larger eveiy year till they flower. The species 

 and varieties are perpetuated by offsets from the bulbs. The 

 species are few ; but from the circumstance of their having 

 been taken in hand by florists, and crossed in every con- 

 ceivable direction, the seedling varieties are in proportion to 

 the originals as fifty to one, and the cross-bred varieties are 

 far more beautiful than the distinct species.
