CARROTS, MANGOLDS AND SUGAR BEETS. 5- 



the deleterious effects to animals, when fed too liberally, by 

 actual experiment it has been found that the wear and tear 

 to the crop, incidental to the plucking of these leaves by an 

 average farm hand, injures it more than the value of the 

 leaves after they are gathered. 



Were it not for the enormous bulk that an acre will pro- 

 duce in roots when compared with its yield in hay or grain, 

 there would be a serious argument against the growing of 

 them to any extent beyond what might be needed for medic- 

 inal purposes, in the fact that the manure made from them 

 is of so low a value ; and the practical weight of this argu- 

 ment would grow in proportion as farmers acquire a knowl- 

 edge of the most important department of farming. To 

 most farmers a cord or load of manure of cow or horse is a 

 cord or load of equal value ; now this is far, very far from 

 being the fact, as will be seen by the following table which I 

 take from the Scientific Farme?-, compiled by the celebrated 

 Mr. Lewis, who, by his careful experiments has laid the agri- 

 cultural world under lasting obligation. In this table a ton 

 of English hay is taken as the standard, and were all the ma- 

 nure saved, both solid and liquid, from a ton of each of these 

 varieties of food, the ingredients at the market value of the 

 Ammonia, Potash and Phosphoric Acid would be worth as 

 follows : —
