rot began to develop around the point of inoculation in every 
fruit. -(Plate XN} 'Fig-'3.) 
This is conclusive proof that the low temperature of the cold 
storage house will hold the disease in check, but that it does not 
kill the spores of the fungus, and as soon as the fruit is taken 
into a warm place the rot begins to develop. 
Therefore, the recommendation is made that if it is desired to 
hold the rot in check, fruit believed to be seeded with spores of 
the disease be put into cold storage just as soon after it is picked 
as possible and not taken out until wanted for immediate use. 
Dryness and low temperature.—W hile commercial cold storage 
may not be feasible in many cases, certain conditions can be made 
that will very much decrease the amount of damage that this fun- 
gus can do. 
It is of the greatest importance that any building intended as 
a storehouse for fruit be dry and well ventilated. In every case 
of the disease that has come to our notice the damage done was 
very much greater where the fruit was stored in a room or build- 
ing that was damp and poorly ventilated. 
In experiments that we have made by putting cultures of the 
fungus in a room in which the temperature ranged from 41° to 
46° F., the average being 44°, there was no growth at the end 
of a week. The cultures were then taken out and placed in a’ 
warm room and made a good growth in one day. 
In a temperature between 50° and 60° F., the average being 
565° I*., there was a small growth of the fungus at the end of a 
week. 
These observations and experiments indicate that if fruit is 
stored in a building or room that is dry and well ventilated, and 
the temperature kept at 45° F. or below, the growth of this 
fungus will be retarded and the fruit saved from the rot. 
Dipping the frwit— Theoretically, if a fruit seeded with the 
spores of a destructive fungus disease is dipped in some solution 
known to be able to kill the spores, the liability of damage to the 
fruit from the fungus diseases ought to be greatly reduced. 
Iixperiments to determine the practicability of this theory have 
been made. Rhode Island Greening apples badly affected with 
the scab were secured for the work. This variety was selected
