SUCCESSION OP CROPS. 127 



that ought to enter into the system of cropping, but these 

 plants require a deep and not too compact soil, in order that 

 their roots may fix themselves firmly. 



Flax, hemp, and corn require a good soil, and can be 

 admitted as a crop only upon those lands that are fertile 

 and well prepared. 



Light and dry soils cannot bear the same kind of crop as 

 those that are compact and moist. 



Each kind of soil, then, requires a particular system of 

 crops, and each farmer ought to establish his own upon a 

 perfect knowledge of the character and properties of the 

 land he cultivates. 



As in each locality the soil presents shades of differ- 

 ence, more or less marked, according to the exposure, 

 composition, depth of the soil, &/C., the proprietor ought 

 SO to vary his crops, as to give to each portion of the land 

 the plants for which it is best adapted ; and thus establish a 

 particular rotation of crops upon the several divisions of his 

 estate. 



The wants of the neighbourhood, the facility with which 

 the products may be disposed of, and the comparative value 

 of the various kinds of crops, should all be taken into the 

 calculation of the farmer, in forming his plan of proceed- 

 ings. 



In England and some of the northern countries, the cul- 

 tivation of barley returns frequently in their successive 

 crops, because the number of breweries afford a sure mar- 

 ket for that grain. In Belgium, Russia, and upon the bor- 

 ders of the Rhine, rye is generally cultivated on account of 

 immense distilleries of spirit : the wants of the great num- 

 bers of animals that are supplied by the malt and refuse of 

 these works, gives every encouragement for the cultivation 

 of that particular kind of grain. 



The cultivation of woad and madder would be more ad- 

 vantageous in the vicinity of great manufactories, where 

 coloring is executed, than in those countries which afford 

 no consumption of these articles. In France, where the 

 abundance and low price of wine will not permit us to hope 

 for any market for beer; in France, where the greatest por- 

 tion of the people live principally upon bread made from 

 wheat, that grain is cultivated everywhere, where it can be 

 made to grow ; only the inferior soils are appropriate to the 

 cultivation of other grains. 



There is another point in regard to crops that ought to
