 HARDENING-OFF. By this term gardeners intend the 

 gradual preparation of plants to endure exposure to a 

 colder and more airy situation. Thus, before bedding- 

 out geraniums, or ridging-out cucumbers, in open beds, 

 the plants that have been nursed under glass are, by 

 degrees, exposed to more air and less warmth, by opening 

 the lights wider, and for a greater length of time, not 

 only by day, but by night, until they become inured to 

 so low a temperature as to suffer no check by being 

 placed in the open ground.

HARDY PLANTS are those which endure uninjured 

 our seasons without protection. 



HAREBELL. Campanula rotundifo'lia. 



HARES and RABBITS are deterred from injuring trees 

 and shrubs, by mixing night-soil and clay hi water, 

 and daubing it over the stems, with a brush, in November ; 

 and, if the winter proves very wet, in February. The 

 November dressing is, however, generally sufficient. 

 This mixture has stopped their depredations entirely, 

 even when they had commenced operations.
