HORSE-CHESTNUT. JSscuIus. 

 There are the following species and

 chestnut. Asia. Seeds sown in March. 

 Flowers in May. Height forty feet.

crowns of the roots, form the best ; 

 those taken from the centre never be- 

 coming so soon fit for use, or of so fine 

 a growth. If the latter are, however, 

 unavoidably employed, each set should 

 I have at least two eyes ; for without one 

 ' they refuse to vegetate at all. For the 

 obtaining a supply of the crowns, any 

 inferior piece of ground, planted with 

 sets six inches apart and six deep, will 

 furnish from one to five tops each, and 

 may be collected for several successive 

 years with little more trouble than 

 keeping them clear of weeds ; but the

 characteristics as the preceding, but 

 are propagated by grafting in March.

Horse-chestnuts all require a light, 

 rich, well-drained soil, and a sheltered 

 situation, being much injured by violent 

 winds. When in blossom they are 

 strikingly beautiful, and their round 

 Leads group well with trees having 

 more pointed forms. They may all be

 latter season for moist ones. 



The sets are inserted in rows eighteen 

 inches apart each way. The ground 

 should be trenched between two and 

 three feet deep, the cuttings being 

 Pale scarlet horse- 1 placed along the bottom of the trench, 

 and the mould turned from the nest 

 one over them, or inserted to a similar 

 depth by a long blunt-pointed dibble. 

 They should be placed in their natural 

 position, which has considerable influ- 

 ence over the forwardness of their 

 growth; the surface raked level, and 

 kept clear of weeds until the plants 

 are of such size as to render it unneces- 

 sary. The mould ought to lie as light 



grafted on the common horse-chestnut, as possible over the sets ; therefore,

HORSE-RADISH. Cochlearia Armo-

 soil, kept as much as possible in a mo- 

 derate but regular degree of moistness. 

 Hence the banks of a ditch, or other 



treading on the beds should be carefully 

 avoided. The shoots make their ap- 

 pearance in May or June, or even ear- 

 lier if they were planted in autumn.
