 Through courtesy of Dr. Fulton I have received 

 the following note: 

 In August 1912, peanuts {Arachis hypogaea) of the Spanish 

 variety growing in Granville county. North Carolina, on soil 

 known to be infected with Bacterium solanacearum (Erw. Sm.), 

 were observed to be dying to the extent of 15 per cent of the 

 planting. Examination of stem and root of the affected peanut 

 plants showed discoloration and disorganization of tissues 

 closely similar to those characteristic of Granville wilt of 

 tobacco. The newly affected parts contained numerous bac- 

 teria. Pure cultures were obtained from which both young 

 and old peanut plants were successfully inoculated on several 

 occasions, the disease induced being similar to that observed 

 in the field. The organism was reisolated from such artificially 

 infected plants, and this culture again used for infecting the 

 peanut. Young and old tobacco plants were inoculated with 

 the original cultures from peanut, with the production of dis- 

 ease similar in all respects to Granville wilt of tobacco, and the 

 typical organism was reisolated from these artificially infected 

 tobacco plants. Cultures from naturally infected tobacco 

 and pepper plants produced the disease in peanut. 



Cultures of three strains of the bacterium from peanut were 

 compared with cultures from tobacco and from pepper on 

 various media, such as potato agar, nutrient gelatin, potato 

 strips, peptone broth, glucose broth, beef broth, potato broth, 

 milk, and litmus milk. The cultural features on these several 

 media were similar for alt the strains tested, and agreed with 

 the original descriptions for Bacterium solanacearum. 



In size and shape, and in reaction to the ordinary stains, 

 these several strains agreed with Bacterium solanacearum. 



The facts lead to the conclusion that peanut is susceptible 

 to attack by Bacterium solanacearum.

No advantage was obtained from flooding infected fields 

 for some weeks. Very hopeful results were obtained Irom 

 the planting of selected sound seed.
