GENERAL REMARKS. 15 



Plants which produce luxuriant tops, so as to. shade the 

 land, to be succeeded by such as yield small teps, 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 rota- 

 tion of crops, for at least as long a period as it remained 

 under such permanent crops. Hence in all gardens ju- 

 diciously managed, 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 re- 

 newed on the same principle, as often as they fail to produce 

 luxuriantly. Indeed, no two crops should be allowed to 

 ripen their seeds 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 

 exhausting crops ; and the succession of crops should be 

 so arranged, that the ground be kept occupied by plants 

 either valuable in themselves, or which may contribute to 

 the increased value of those which are to follow; and the 

 value of the labour required to mature vegetables, and pre- 

 pare them for market, should be always taken into conr 

 sideration. 



Many kinds of seed, such as Asparagus, Capsicum, 

 Celery, Fetticus, Leek, Lettuce, Onion, Parsnip, Parsley, 

 Rhubarb, Salsify, Spinage, &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 may 

 answer for small beds as a substitute : after the seed is sown 

 and the ground well raked, take a board (or boards) the 

 whole length of the bed, lay them flat on the ground, begin- 

 ning at one edge of the bed, walk the whole length of the, 

 ted, this will press the soil on the seed, then shift the boaads
