drouth than any other clover ; it is hardy enough 

 to produce well at our higher altitudes and is so 

 strong in its growth that it will produce a large 

 amount of vegetation to plow under as a green 

 manure. 



Sweet clover is one of the strongest nitrogen- 

 gathering legumes. The bacteria on the roots of 

 sweet clover are said to be the same as those 

 which live on the roots of alfalfa, and soil from 

 sweet clover land can be used to innoculate al- 

 falfa fields with the nitrogen-gathering bacteria. 

 We have never examined sweet clover roots with- 

 out finding the nodules. On this account it is 

 one of the very best plants to grow for enriching 

 the soil in nitrogen. 



Sweet clover makes a stock feed which is 

 valuable if it is properly treated. Breeding this 

 plant has been commenced with the hope of pro- 

 ducing a variety which will not have the bitter 

 and sweet flavor which makes it unpalatable to 

 stock. As it is, hay properly cured and fed, 

 give remarkably good results. A number of cat- 

 tle men have testified that they had little diffi- 

 culty teaching their stock to eat sweet clover hay 

 and that they did well on it. In some experi- 

 ments carried out at the Wyoming Experiment 

 Station, sweet clover hay was fed to fattening 

 lambs with corn and other grain, and the butcher 

 who dressed the lambs testified that they were 

 the heaviest and fattest he ever saw.
