GENERAL REMARKS. 
Plants which produce luxuriant tops, so as to shade the 
land, to be succeeded by such as yield small tops, or narrow 
leaves. 
Plants which during their growth require the operation of 
stirring the earth, to precede such as do not admit of such 
culture. 
Ground which has been occupied by Artichokes, Aspara- 
gus, Rhubarb, Sea Kale, or such other crops as remain long 
on a given spot, should be subjected to a regular rotation of 
crops, for at least as long a period as it remained under such 
permanent crops. Hence, in all gardens judiciously man- 
aged, the Strawberry bed is changed every three or four 
years, till it has gone the circuit of all the compartments ; 
and Asparagus beds, &c., should be renewed on the same 
principle, as often as they fail to produce luxuriantly. In- 
deed, no two crops should be allowed to ripen their seed in 
succession in the same soil, if it can be avoided ; because, if 
it be not exhausted by such crops, weeds will accumulate 
more than on beds frequently cultivated. 
Manure should be applied to the most profitable and ex- 
hausting crops ; and the succession of crops should be so 
arranged, that the ground may be occupied by plants either 
valuable in themselves, or which may contribute to the in- 
creased value of those which are to follow ; and the value of 
the labour required to mature vegetables, and prepare them 
for market, should be always taken into consideration. 
Many kinds of seed, such as Asparagus, Capsicum, Celery, 
Fetticus, Leek, Lettuce, Onion, Parsnip, Parsley, Rhubarb, 
Salsify, Spinach, &c., will not vegetate freely in dry weather, 
unless the ground be watered or rolled; where these is no 
roller on the premises, the following contrivance may answer 
for small beds as a substitute : after the seed is sown, and the 
ground well raked, take a board the whole length of the bed, 
lay it flat on the ground, begin at one edge of the bed, and walk 
the whole length of it ; this will press the soil on the seed, 
then shift the board till you have gone over the whole bed.
