absorption by the rays of the sun. and the consequent necessity of frequent 

 watering, which bakes the soil, and does much mischief to seeds of slow 

 growth. Toward the middle or end of May, many of the seedlings will l)e 

 ready for transplanting to borders: but previous to this exposure, it will be 

 necessary to harden them, preparatory feo removal, by gradually admitting air 

 to the frame both day and night. 



Biennials are those plants that do not generally flower the first year, and 

 are only in perfection one season. Perennials continue to flower several years 

 in succession. The seed may be sown, as has already been stated, at times 

 when the ground is moist, but not very wet, from the first of April to August. 

 Many of them may be raised in the open ground like hardy annuals, and trans- 

 planted; but tender, or half-hardy kinds should be sown as dij-ected for haU- 

 hardy annuals. As they do not generally bloom the first year, they may be 

 thinned out or removed from the seed beds as soon as they are well rooted, and 

 planted either into different parts of the garden, or into nursery beds, in rows, 

 a foot apart. The half-hardy or tender biennials must be kept during the 

 winter in a green bouse or dry cellar, and tender perennials must be protected 

 from frost, by a cloth or mat l)eing tied or fastened around them, and covered 

 afterward with leaves or litter.
