they advance. The first, or short stakes, 
are merely to mark where the lar.ojer are 
meant to be driven into the ground when 
wanted ; otherwise there Avould lie danger 
of injuring the plants. Three stakes, five 
feet long, will be necessary for every clus- 
ter or large root : they must be tied round 
from stake to stake, Avith soft tarry spun- 
yarn, or strong double strands of bass-mat. 
Hollyhocks, &c. should be tied up in the 
same manner. 
The roots of the Dahlia are said to be 
nutricious and wholesome ; and the French 
gardeners enumerate them among their

nament to the dower garden.

It Avould be a very neat and not expen- 
sive improvement, to have a number of co- 
ver-pots of various sizes, according to the

to furnish the stages. 
The doAver-pots which I wish to recom- 
mend are made a^ the potteries. They are 
of the same materials as the common pots.
