HOW, WHKN, AND WHEKE TO SOW SEEDS. tl 



1st. Plants, of the same family, should not be planted to 

 succeed each other. 



2d. Plants, which occupy the ground for a number of 

 years, such as Rhubarb and Asparagus, should be succeeded 

 by annual plants. 



3d. Crops, grown for heads, such as Cauliflower, Cabbage, 

 etc., should be succeeded by crops grown for their bulbs or 

 roots. 



It is hardly practicable to vary crops according to any set 

 rule, the demand in different localities for certain articles 

 being greater than in others. Generally variety enough is 

 demanded to allow of sufficient rotation. Our system of 

 heavy manuring, deep culture, and taking two crops from 

 the ground each season, seems to do away in a great meas- 

 ure with the necessity for systematic rotation, which would 

 often be found to be very inconvenient. The crops of all 

 others, that we find most benefitted by change are, the 

 Cabbage tribe, together with the allied Turnip, Radish, etc., 

 while on the other hand we have grown Onions successively 

 on the same ground for ten years the last crop just as 

 good as the first ; but as a rule of safety, vary whenever you 

 can. 



QUANTITY OP SEEDS PER ACRE. The quantities given 

 below are somewhat higher in some kinds than the usual 

 estimates, our experience showing us that in weak vegetat- 

 ing seeds, such as Parsnips, Carrots, etc., it requires num- 

 bers, particularly on stiff soils, to force through plants 

 enough to form a crop ; more seed is required when sown 

 during the dry hot months of summer, than if sown in the 

 cooler and moist seasons of spring and fall, hence quantities 

 are regulated accordingly.
