by cutting close away, with a sharp knife, 

 the lateral young shoots proceeding from 

 the upper part of the stems, in July and 

 August ; which will otherwise incline the 

 steins to lean or fall sideways. 



Culture of Heli antJius Tuberosus. 

 THE root of this plant bearing some re- 

 semblance to that of potatoe, may be con- 

 sidered by some persons in its nature as ana- 

 logous ; but such idea is erroneous, the 

 former being perennial, and the latter an- 

 nual in duration; that like most other pe- 

 rennial herbaceous plants, the Jerusalem ar- 

 tichoke being planted early in autumn, its 

 root being impervious to frost, will more 

 early and freely vegetate the following 

 spring^ and effect a far more speedy and 

 effectual shade than these planted in the 

 spring ; observing to plant them soon after 

 they are out of the ground as possible, as 

 on the roots becoming dry their vegetation 

 will be retarded.
