Describes a disease of muskmelons said to lie widely prevalent 

 and attributes it to bacteria. From a statement on the bottom 

 f P- 354 respecting the appearance of some of the leaves it 

 is possible that a portion of these plants were attacked by 

 Bacillus tracheiphilus. but all could not have been, since this 

 organism does not cause a moist soft rot of the stems such as 

 Dr. Halsted particularly describes. He says it is a disease com- 

 plained of especially in the South (Mississippi) and also that: 

 "This disease is quick acting, and healthy tissues, when inocu- 

 lated, soften and decay in a few hours" Possibly this disease 

 was due to the soft rot organism since described by (biddings as 

 Bacillus melonls.

The first three pages are on bacterial wilt. Spraying experi- 

 ments in several localities were made with Bordeaux mixture, 

 potassium sulphide, sulphur, and Laurel green, but no con- 

 clusive results were obtained. " It is probable that the suscepti- 

 bility of melons to contract the bacterial wilt is unaffected 

 by the fungicides commonly used against fungous diseases. 

 Removing and destroying all wilted vines is the only practical 

 method of preventing the spread of the disease."

 than usual." An excellent figure of wilting and wilted squash- 

 vines is given.

Kirk believes that he has observed the wilt of cucumbers 

 due to Bacillus tracheiphilus. in New Zealand, but the specific 

 organism was not isolated.

" It is difficult to isolate this bacillus or to keep it alive, for 

 it grows feebly or not at all in the ordinary media of the labora- 

 tory, especially in gelatin media. We have devised, prepared, 

 and tried many special media and have found several in which 

 the organism grows freely, the growth in certain gelatin media 

 being especially copious and characteristic.
