with this species. By inoculations of varying depths, grrdations 

 in development between the natural rot and that just described were 

 obtained, showing that the fungus is aerobic.

Spotted tomatoes were left on the vines 

 for weeks after ripening, but no further growth 

 of the spot took place. The first indication 

 of decay was the usual watery softening of 

 the tissue, leaving the spot as dry as pre- 

 viously. As before stated, the rot appeared 

 with the first fruits. It continued for about 

 eight weeks, and then disappeared entirely. 

 It was then about the middle of May, and the 

 plants were on the decline. Galloway states 

 that, " however long continued, the rot always 

 begins on the first fruit." This is the only 

 previous observation made as to duration. 



Tf^e smallest infected fruit found by the 

 writer measures three-fourths of an inch in 

 diameter, and inoculation experiments with 

 fruit under this size have been unsuccessful. 

 These results agree in a general way with 

 those of Galloway and Whitehead. In the 

 former case the fruit was one-third to one-
