This table is very suggestive in many ways : — by it we see. 

 that there are varieties of food, the manure from which is 

 worth more than the cost of the food itself. In its appli- 

 cation to the feeding of Mangolds, it at a glance suggests 

 the wisdom of feeding at the same time a portion of some- 

 thing richer and more concentrated. By so doing the qual- 

 ity of the manure is vastly improved and the crops will not 

 be slow to discover it. There is still another reason for 

 feeding these rich foods while using roots ; it enables the 

 armer to feed with profit Lis straw or inferior varieties of 

 hay. Says Prof. Stockhardt, "the full benefit to animals de- 

 rivable from feeding roots is secured only when the pro- 

 per proportion of substances rich in nitrogen are fed with 

 them ; accordingly, about two pounds of oil-cake should be 

 fed with each hundred pounds of beet root, or other foods 

 may be substituted in the same proportion as they are rich 

 in nitrogen." 



Recent researches have determined a fact of great value 

 to agriculture ; that to get the most profitable results from 

 food the Albuminoid and Carbohydrate elements should 

 bear a certain proportion to each other, and that while a de- 

 crease in either of them from this proper proportion means 

 insufficient food, and a consequent loss of flesh, fat or milk, 

 an excess of either means money wasted. The proportion 

 for cows that are dry and oxen when not at work, is about,
