ed that a course that is suitable 

 for one soil, may not be so for ano- 

 ther. 



In countries where a spirited at- 

 tention to agriculture has lor a long 

 time subsisted, one would expect, 

 that people have nfiost probably 

 adopted the best courses. It is 

 not amiss, then-fore, to observe 

 what courses they generally prefer 

 in Biitai.j and Ireland, taking care 

 not to go into a rash and inconsi- 

 derate imitation of them, without 

 making allowance for local differ- 

 ences, (fee. 



A cornmon course in Ireland is, 

 turnips, barley, clover, wheat : or, 

 potatoes, barley, clover, wheat. 



From the account that Mr. 

 Young gives of the courses in dif- 

 ferent places, wiiich he passed 

 through in his northern tour, the 

 following things are observable. 

 That where they do not fallow, 

 green and white crops follow each 

 other alternately; and thit wheat 

 follows clover oftener than any 

 other crop : That where fallowing 

 is practised, wlieat is nest, and 

 after it sometimes another white 

 crop; but not generally. It ought 

 to be never. 



The courses of crops in Ireland, 

 will furnish nearly the same obser- 

 vations. 



The judicious farmer knows, 

 that some regard must be had to 

 the nature of the soil in a course oi 

 crops. Those crops wliich require 

 a liyht soil, should tn .ke no part of 

 the course in a stitf one, and vice 

 versa. 



But supposing the European 

 courses to be the best that can be. 

 some variation is surely to be made 



in this country ; what that varia- 

 tion is, experience must discover. 

 Not only our climates, but also 

 our crops are ddferent. We raise 

 some crops that they do not, and 

 not all that they do raise. But a 

 rule that is fit to be extended to all 

 countries, is, that two impoverish- 

 ing crops should seldom, or never, 

 succeed each other in a course. 

 And it is certain, that white or grain 

 crops in general, are apt to impover- 

 ish the soil, as they continue to draw 

 nourishment from the earth, for 

 some time after the leaves are 

 dead, and cease to receive nour- 

 ishment from the air. And all 

 plants that bear an oily seed, rob 

 the soil of nuich of its vegetable 

 food : Such are flax and hemp, sup- 

 posing them to continue in the 

 soil till (he seed is ripe. 



Reasoning from experience and 

 observation, I am led to believe, 

 that the following are as good 

 courses, as may be expected to be 

 introiiuced in this country. On 

 light wartn soils, the hist year, 

 corn dunged, pease, or potatoes : 

 2d year, rye, barley, or buck wheat : 

 the 3d, and 4th, clover: the 3th, 

 wheat : the 6th, and 7th, clover. 

 On cold and stiff soils, first, oats or 

 potatoes : 2d, potatoes well dunged : 

 3d, flax, or wheat : 4th, grass, and 

 so on till it needs to be broken up 

 again. Though these may serve 

 tor general rules, yet as there is a 

 great variet} in soils, and some far- 

 mers car; obtain manure in greater 

 plenty than others, each farmer 

 must ei'.deavour to accommodate 

 his courses to his soil and other 

 circumstances.
