New York AGRICULTURAL EXPERIMENT STATION. 291 
SUMMARY. 
Although the fumigator was severely tested in two of the more 
important points in its construction, the danger of leakage and 
spreading at the base, it proved entirely satisfactory. Heavy 
charges of sulphur smoke and hydrocyanic acid gas were used 
to ascertain whether there was any leakage between the felts, 
but none could be detected. The frame has also remained rigid, 
there being no indications of spreading at the base or otherwise 
becoming out of shape. 
In constructing the fumigator, a ight but rigid frame should be 
aimed at and much care should be taken to make the adjustable 
side a fairly tight fit. The small metal flanges at the base of the 
frame are also of special importance, as they prevent the door 
from slipping down and thus allowing the gas to escape at the 
top.
