had become branched end septate. Only two of the agar cells 
had germinated spores. The others probably got too hot in 
drying over the flame. There was still no change in the fusoid 
spores. More transfers to potato-agar tubes were made. 
FIELD INOCULATIONS (IN 1907). 
Ascosporic and pycnidiosporic inoculation of muskmelon.— 
Two hills of muskmelons, which grew vigorous, healthy vines, 
having some full grown melon fruits attached, were selected in 
the garden, and on August 12 the plants of one hill were inocu- 
lated with pycnidiosporic and that of the other with ascosporic 
mycelium. The inoculating was done on the internodes by 
making tangential cuts into the cortex, inserting a bit of my- 
celium from potato-agar tubes and covering with grafting wax. 
Eight ascosporic and seven pycnidiosporic inoculations were 
made. Three checks were prepared for each group. 
On August 24 seven of the ascosporic inoculations had pro- 
duced the disease on the infected parts of the vine, showing the 
usual water-logged conditions of the green tissue farthest re- 
moved from the center of infection. The cortex nearer the in- 
oculations was dead and dry, having a greyish color, and specked 
with dry drops of gum here and there. The general appearance 
of all but one of the plants was fresh and green, in fact, aside 
from the dead cortical girdles at the points of inoculation, 
the vines seemed normal. However, one of the vines looked 
rather flaccid and its leaves drooped slightly. Only four of 
the seven points inoculated with pycnidiosporic mycelium had 
become infected, producing a result just like the one described 
above; but two of these infections had a few pycnidia at the 
edges of the grafting wax. 
The plants were reexamined on September 16. The two 
formerly wilted plants and one inoculated with pyenidiosporic 
mycelium had died while two of those infected with ascosporic 
mycelium were very much wilted. AI] diseased parts contained 
fruiting bodies of the fungus. Both pycnidia and perithecia 
were present on several infections of each hill, but the asci
