IV. The disease of Baldwin applies, known in New York as 
the Baldwin fruit-spot, is characterized by small brown sunken 
spots which occur on the fruit about the time it is gathered. Un- 
derneath the spots the tissue is light brown and spongy. ‘T'he 
diseased tissue contains no fungus hyphe. In moist chamber the 
spots do not enlarge and no funens appears on them. On various 
culture media the affected tissue produces no growth. The con- 
clusion is that the disease is not caused by fungi or bacteria. How- 
ever, the work of other investigators indicates that similar spots 
on the Baldwin and other varieties may be due to parasitic organ- 
isms and hence the desirability of greater care in the writing of 
descriptions. 
_Y. A species of Fusarium has been found producing a serious 
leaf spot disease of carnations at Syracuse. It occurred upon 
plants so situated that the direct sunlight could not reach them. 
The fungus gains entrance through breaks in the epidermis made 
by rust sori. It is not improbable that it may be identical with 
the carnation stem-rot Pusarvum. 
VI. Chaetomium contortum Pk., a rare fungus hitherto found 
only:on lily bulbs on Long Island, has occurred at Geneva under 
circumstances which aroused the suspicion that it is parasitic on 
barley seedlings; but an inoculation experiment showed that it is 
not parastic. 
I. A BACTERIAL ROT OF ONIONS.* 
In the autumn of 1898 the report came to the Experiment 
Station that the onions in Orange Co., N. Y., were rotting badly. 
Upon investigation it was found that in nearly all of the fields in 
this great onion growing district there was a considerable amount 
of rot. In many cases from one-third to one-half of the crop had 
to be rejected on account of it, and the remainder was not readily 
salable because news of the rot had reached New York city pro-

motion of Agricultural Science, August 22, 1899, and will subsequently be 
published in the Proceedings of that Society.
