planting off-sets from the roots in the latter end of summer, when 

 their stems and leaves decay. The roots may be divided every se- 

 cond or third year. 



In the two first sorts, the off-sets may be planted out in nursery- 

 beds for a year or two, to become sufficiently strong, when they may 

 be removed into warm sheltered dry borders; the first being shel- 

 tered from frost in severe winters, and the latter in very severe wea- 

 ther, by being covered with tanner's bark, straw, or peas-haulm. The 

 second sort may also be increased by seeds sown in pots, and plunged 

 in a hot-bed. 



The other sorts must be planted out in small pots filled with 

 light earth, scj)arately plunging them in the bark-bed of the stove. 

 They should be kept constantly in the tan-bed, and have the ma- 

 nagement of other tender bulbs. In this way they generally succeed 

 well. 



The two first sorts afford variety in the dry warm borders of the 

 pleasure-ground, and the other kinds produce variety as well as 

 fragrance in the stove collections.
