GENERAL REMARKS. 21 



in wheat : after being heated in a kettle until it becomes 

 thin, it may be stirred in among the grain until it becomes 

 saturated. The wheat should afterward be mixed with a 

 sufficient quantity of wood ashes to dry and render it fit for 

 sowing. 



To prevent depredations from crows, steep corn in strong 

 saltpetre brine, sow it over the land, or steep your seed corn ; 

 and if the crows once get a taste, they will forsake the field. 



Perhaps the next important point to be attended to is the 

 most proper rotation of crops. Virgil, who was a philoso- 

 pher as well as a poet, very justly observes, that " THE TRUE 



REPOSE OP THE EARTH IS A CHANGE OF ITS PRODUCTIONS." 



It is a curious fact, that a plant may be killed by the 

 poison which it has itself secreted, as a viper may be de- 

 stroyed by its own venom. Hence it has been very gene- 

 rally noticed, that the soil in which some particular vege- 

 tables have grown, and into which they have discharged the 

 excretions of their roots, is rendered noxious to the prosperity 

 of plants of the same or allied species, though it be well 

 adapted to the growth and support of other distinct species 

 of vegetables. 



It is proved by experience, that fall Spinach is an excellent 

 preparative for Beets, Carrots, Radishes, Salsify, and all other 

 tap, as well as tuberous rooted vegetables. 



Celery or Potatoes constitute a suitable preparative for 

 Cabbage, Cauliflower, and all other plants of the Brassica 

 tribe; as also Artichokes, Asparagus, Lettuce, and Onions, 

 provided such ground be well situated, which is a circum- 

 stance always to be duly considered in laying out a garden. 



Lands that have long lain in pasture are, for the first three 

 or four years after being tilled, superior for Cabbage, Tur- 

 nips, Potatoes, &c., and afterward for culinary vegetables in 

 general. 



The following rules are subjoined for farther government : 



Fibrous rooted plants may be alternated with tap or 

 tuberous rooted, and vice versa.
