Control. 
The tests showed that the thirteen inoculated seedlings were 
severely infected, while the two controls remained healthy. 
Thus all plants inoculated developed the disease. Evidence of 
infection could be observed one day after inoculation, because 
of a blackening of the tissues about the points of insertion. 
The controls, which were injured in the same way, and into 
which sterile water was introduced, remained perfectly healthy. 
The rapidity with which the organism attacks the tissues is 
shown by the fact that it advanced 10 centimeters in a period 
of ten days. Microscopic examination of the diseased portion 
showed in all cases the presence of the large, thin-walled, ir- 
regular, nonseptate, granular mycelium, characteristic of Phy- 
tophthora faberi Maubl. No bacteria had gained entrance at this 
early stage. Only a, slight odor was evident, showing that the 
stench in older cases is produced by putrefying bacteria that 
follow the attacks of the fungus. In all cases reisolations were 
positive. 
With other hosts . — In order to find out whether the fungus 
was omnivorous in its habits, and to determine whether it was 
similar, in this respect, to Phytophthora faberi Maubl. isolated 
from cacao, inoculations were made in fruits of cacao and pa- 
paya, and in seedlings of Hevea rubber. The cacao fruits were 
upon trees in the field, while those from papaya were placed
