HI. Not Lacking in Carbohydrates. 



It will also be seen from the table that the 

 leguminous hay only lacks about 5 per cent, of 

 being as rich in the heat-producing elements, 

 carbohydrates and ether extract, as the hay of 

 grasses. On the other hand, it will require in 

 most cases no supplementary nitrogenous food 

 in the form of expensive meals as wheat shorts, 

 gluten meal, and cottonseed-meal, as does the 

 hay of grasses. 



Leguminous plants are valuable, then, in that 

 (i) they do not exhaust the soil of its nitrogen, 

 but may be made (through their relation with 

 the bacteria) to add to the soil's supply of 

 nitrogen from that of the air; (2) they are deep 

 feeders, and bring up from below and deposit 

 near the surface other kinds of plant-food; (3) 

 they make a more economical food than grasses; 

 (4) that the manure from such crops makes a 

 better fertilizer than that obtained by feeding 

 the hay of grasses. 



D. SPECIFIC CASES. 



I. Red Clover ( Trifoliitm pratense} 

 need only be mentioned, as it is already well 

 known and its value recognized. It is widely 

 grown in the Northern and Eastern States, but 

 is not generally grown so successfully in the 

 South and West as other legumes. It is best to 

 cut it when not more than 20 per cent, of the
