22 GENERAL REMARKS. 



Plants which produce luxuriant tops, so as to shad^ the 

 land, to be succeeded by such as yield small tops, or narrow 

 leaves. 



Plants which during their growth require the operation of 

 Stirling 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 there 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.
