grow freely in any light rich soil. 

 They are propagated by seed, or divi- 

 sion of the roots. The name is said 

 to be derived from the juice of these 

 plants being formerly given to hawks, 

 to clear and improve their sight ; and 

 it is still used for bathing the eyes in 

 ophthalmic disorders.

Hoe. — There are many different 

 kinds of hoes ; but they may be all 

 reduced to two classes : the draw-hoes, 

 which have broad blades, and are used 

 for drawing up the earth to the roots 



of plants, being pulled to the operator ; 

 and the thrust or Dutch hoes, which 

 are principally used for loosening the 

 ground and destroying the weeds, 

 and which the operator pushes from 

 him. 



Hoeing is an operation used for loos- 

 ening the earth, and destroying weeds, 

 where both digging and forking would 

 be injurious to the roots of the plants 

 forming the crop. It is also used to 

 draw the earth up to those plants 

 which send out numerous fibrous roots 

 close to the surface of the ground. 

 This last operation is called hoeing 

 up, and it is generally practised with 

 annual culinary crops.

 yellow loam ; and the plants are pro- 

 pagated by offsets, which should be 

 taken off and replanted in September 

 or October.

Honey Dew is a clammy substance 

 often found on the leaves of trees and 

 shrubs in hot weather ; and it is by 

 some supposed to be produced by in-

 it does injury by stopping up the pores 

 of the leaves ; and it should be washed 

 off as soon as it is discovered.
