tubercle-forming germs. It should be borne in mind that such inoc- 

 ulations are usually not necessary in soil that is already producing 

 tubercles. While the introduction of fresh organisms will generally 

 considerably increase the number of nodules, the effect upon the crop 

 is not appreciable, and it is hardly worth the expenditure of time and 

 labor necessary to make the inoculation. Wherever legumes that fail 

 to produce tubercles are being grown, however, orm those localities 

 where the soil is so poor that legumes will not grow and because of 

 the lack of the proper organisms they can not make a start, every 

 effort should be made to get the bacteria into the soil. — [_Year Booh
