which grows a foot and a half high, sending up many 

 stalks crowned by double fragrant flowers. Varieties 

 red and white j and blows from May to August. Pro- 

 pagated by parting the roots in autumn j or by cuttings 

 of the stalks of the flowers, which, being cut into con- 

 venient lengths, you make three splits in the end of each, 

 of about half an inch up j force the split end into the 

 ground, and they will readily take root if you put a 

 hand-glass over them, and place them where none but 

 the morning sun can get to them. Better still to strike 

 them under a propagation glass in a gentle hot-bed. 

 There are very few prettier, and still fewer sweeter flowers 

 than the double rocket ; but it is said by theorists not 

 to thrive near large cities I think that the smoke of 

 London or Manchester is incompatible with the health of 

 anything animal or vegetable ; but I do not think smoke 

 prejudicial to this plant in particular, for I have seen it 

 remarkably fine in the neighbourhood of London, but 

 never have I seen it so fine as in the .vicinity of the 

 smoky towns of the North of England, where it grows 

 most freely in a strong clayey soil.
