A note of caution is perhaps also warranted to the agents of the Bureau of Entomology 
and others concerning the advice offered inquirers as to remedies for various insects. The 
natural impulse on the part of the expert is to recommend some standard remedial action in 
relation to any insect difficulty reported. Very often, however, the remedial action recom- 
mended, while perfectly sound, is not necessarily applicable to the particular condition 
reported, and may result in a vestly greater cost and harm than the insect complained of. A 
housewife, discovering a silver fish or a small quantity of ants, or a single bedbug recently 
arrived, naturally becomes very much alarmed as to the future security of her house and its 
contents, but it is always a wise precaution, before recommending fumigation with hydrocyanic- 
acid gas or elaborate treatment with powders or other expensive applications which may be 
more or less detrimental to walls, floors, or furniture, to advise Listes remedies and to make 
sure that the insect complained of is more than a chance discovery which may not be repeated 
perhaps for years. The same advice applies to indoor and outdoor plants, whether garden or 
field culture. Many of the insects which are ordinarily complained of and sent for determina- 
tion are undoubtedly chance occurrences which have naearally aroused curiosity and perhaps 
excited fears, but which will doubtless disappear through natural agencies without any 
treatment. 
The wise use of insecticides will repay many times their cost, and any damage to the plants 
will be largely offset by this gain, but the unintelligent or unnecessary use of insecticides may 
often do much harm and at least will be money and time wasted. [C. L. M.]

account of the destruction of the apple blossoms in New Mexico, went to Benton Harbor, Mich. 
Mr. George S. Demuth went to Winchester, Va., recently to assist the county agent there 
in establishing apiaries in two county schools. Interest in beekeeping among farm demonstra-
