worms. Diseased bulbs were left on the surface of the soil throughout 
the whole of the winter. The thermometer at Wisley registered as 
much as 37 ° of frost. The bulbs on being brought into the laboratory 
were examined and eelworms in an active state of life were found. 
Planted diseased bulbs were lifted after being subjected to alternate 
freezing and thawing, and live eelworms were present in the bulbs. 
Conclusion. 
The preventive method which promises best results is that of 
soaking the bulbs for a period of from 2 to 4 hours in water at a constant 
temperature of no° F., and, providing a suitable apparatus be found 
so that the bulbs may be given correct treatment, it will afford an 
economical means of combating the disease. 
At the same time it must here be pointed out that this soaking 
will not prevent attack by eelworms present in the soil. 
Other experiments are on foot this autumn, and the treatment of 
infected ground, and susceptibility of crops to attack, are phases of 
the subject which are under experiment.
