Fig. 1. Seed-inoculated peas (variety Solo) to 
the right; the control to the left. 
We may summarize the results of the inoculations 
in the following way. 
1. Soil-infection gave positive results in all varie- 
ties used. Some of the garden-peas (Stensärt, Champ, 
of Engl.) seem to be more readily infected under labo- 
ratory conditions than others. In these infections the 
root-system became infected and developed but poorty. 
2. With stem-inoculation infection resulted readily 
in the garden-peas when a mycelium-containing medium 
was applied to artificially produced wounds on the stem, 
less readily in the case of intact stems. Infection did 
not follow when mycelium alone was used on intact 
stems. The garden-pea varieties seem to be more su- 
sceptible than the field varieties, with the exception of 
Gröpärt, which readily became infected. 
3. Infection followed most readily when the seeds 
were inoculated and then put to germinate. A typical 
rot was developed at the base of the stem, and the root- 
system became infected as well. 
4. Methods of controlling the disease. 
As to the methods of infection in nature, field-in- 
fection seems to be the only one of importance. A 
great number of samples of seeds taken from badly
