DISEASES AND ENEMIES OF BEES. 223 
scarcely one could at first be discerned. The good results 
claimed to follow a thorough painting of the hive, within 
as well as without, may arise from the closing of its pores 
by the paint, and the 
consequent exclusion 
of these insects. Un- 
der certain circum- 
stances, however, this 
gain may be counter- 
balanced by disadvan- 
tages otherwise men- 
tioned. A common 
seed-glass, such as are 
sold by opticians (fig. 
87), for detecting adul- 
terations or impurities 
in seeds will answer. 
Better still, as afford- 
ing a higher power, 
and being more con- 
venient in use, for observing these parasites, is the 
American Agriculturist Simple Microscope (fig. 88), of- 
fered by the Orange Judd Company. 
The progressive bee-keeper will here find interesting 
ground for investigation, which has a more direct bearing 
upon Vital points in his pursuit than may at first be sup- 
posed. I anticipate that the discoveries of the near fu- 
ture in this direction will not only be surprising, but en- 
lighten us materially in regard to many mysteries for 
which we are as yet unable to furnish a solution. 
BEE-MOTH. 
If we combine into one phalanx all other enemies of the 
bee, and compare their ability for mischief, with that of 
the bee-moth, we shall find their powers of destruction
