A new disease of sweet corn. — Mr. Stewart has given consider- 

 able time to the study of a new disease of sweet corn to which 

 the early varieties of this crop are much subject in the market 

 gardens of Long Island. He has demonstrated that this disease 

 is bacterial in its nature, which is the first step necessary to a 

 discovery of methods of prevention. The subject needs further 

 study, and no remedial measures can now be recommended. Pre- 

 vention may perhaps be secured by care in the selection of seed 

 and by the planting of resistant varieties. 



Potato scab. — ^The ploughing in of a crop of green rye had no 

 effect in preventing potato scab. The disease appeared to be 

 aggravated rather than checked. 



Potato stem hlight. — This was not communicated by planting 

 diseased tubers, neither were peppers, tomatoes, egg plants or 

 plants of other species infected by contact with diseased potato 

 tubers. 



Carnation rust. — The application of a solution of common salt 

 neither prevented the rust nor benefited the growth of the car- 

 nation plants.
