washes, representative areas of the trees selected for treatment 
were first carefully wrapped with paraffin-paper, the outer edges 
being bound with bands of cotton and string to prevent any seep- 
age by the liquids. After the applications of the sulphur washes 
were dry, the paper was removed, the cotton bands being retained. 
As a basis for estimating results, areas of bark having 180 to 
200 old scales to the square inch were marked off with pins on the 
check and treated trees. On June 15 these areas were examined 
to determine the effects of the treatment upon the young scales. 
The results upon one treated tree and one untreated tree, both 
with smooth bark, are indicated by the accompanying table. 
The figures given show the number of young scales to each area 
respectively.

The results of a sulphur wash upon a much infested tree with 
rough bark are shown by the following comparison of the condi- 
tions of a sprayed and not sprayed tree with respect to the number 
of young scales settled upon areas of similar dimensions which, 
as before, consisted of representative sections of bark selected 
previous to the treatment. The date of the application of the 
wash and the time of the examination of the young scales are the 
same as with the preceding trees.
