Explanation of the first two rows of figures in ike prece- 

 ding Table. 

 The number of heaps consisting" of one load each, 

 laid at five yards distant, is 193 to cover one acre; at 

 two heaps to a load 98 ; 2ii three heaps, 64; at four., 43; 

 and so to the end: — each of the following rows is to be 

 read in a similar manner. 



CULMIFEROUS CROPS. 



The varieties of corn ranked as culmiferous, or rob- 

 bing ones, are, wheat, barley, oals, and rye ; to which 

 may be added Indian corn, and millet. These we are 

 inclined to consider as bearing hard upon the soil. Du- 

 ring the ripening of the seed, they draw probably their 

 whole nourishment from tha soil ; as the leaves by this 

 time, being dry and withered, must have lost their pow- 

 er of drawing nourishment froni the air. But such 

 plants, while young, are all leaves ; and in that state 

 draw much of their nourishment from the air. Hence it 

 is, that when cut green for food to cattle, a culmiferous 

 crop is far from being a robber. It is by fixing upon 

 the most proper of each for the soil cultivated, that the 

 judgment of the farmer is correctly ascertained. In 

 other respects, such as the exhaustion of the ground, 

 we view it as a matter of little importance Avhich of 

 them is preferred. The above are also called whiie 

 crops. 



LEGUMINOUS CROPS. 



Though culmiferous crops have, in all ages, been re- 

 garded as most profitable, there is no doubt, but that ru- 

 ral management is most saitably exercised when due 

 attention is paid to the preparative crops, orthose which 

 are naturally calculated to enrich or fertilize the soil, 

 and to furnish an increased stock of manure. These 

 preparative or enrichiu'r crops are usually called iegu- 

 miaous ; under this head are ranked, beans, peas, clov- 

 er, potatoes, ruta-baga, mangel-wurlzel, turnips, cabba- 

 ges, carrots, parsnips, and buckwheat. The above are 

 also called green crops. 



ROTATION OF CROPS. 



No branch of husbandry requires more skill and sa- 

 gacity than a proper rotation of crops, so as to keep
