The utilization of fish in this way is an old suggestion, and a very 
practical one under some circumstances. Many people suffer from the 
mosquito plague when the insect breeds in a circumscribed and easily 
accessible place, and where it could be destroyed by some such method 
as that used by the level-headed Englishman. 
THE TRUE BUGS OR HETEROPTERA OF TENNESSEE.” 
No. 3 of Vol. rv of the Bulletins of the Tennessee Experiment Station 
is devoted to the Heteroptera of that State, and in it Prof. Summers 
has given an excellent series of keys to the families and genera of this 
division of insects. In an introductory note he treats of the general 
characters of the group, describes the structures mainly depended upon 
in classification, and presents a figure in which these structures are 
earefully explained. 
The keys for the determination of the genera are models, and it is 
only to be regretted that such families as the Capside, Lygeide, Coreide 
and Pentatomidz could not have been treated in the same manner, but 
any one familiar with the Hemiptera can appreciate the difficulty of 
presenting adequate keys in these families at present. 
The bulletin closes with a brief discussion of remedies to be used 
against the Hemiptera and is naturally devoted to the preparation 
and use of kerosene emulsion, which is recognized as of most general 
use in the treatment of these suctorial insects. 
With the exception of a few oversights in proof-reading, leaving some 
misspelled technical names, the typography is excellent, and the figures 
will add much to the usefulness of the bulletin to the general public. 
The description of species would in many cases be insufficient for 
certain determination, but, for the purpose intended, the treatment of 
the species mentioned is commendable.—Herbert Osborn. 
THE PHYLLOXERA IN FRANCE AND THE AMERICAN VINE. 
We have not before noted the encouraging Associated Press dispatch 
published in our papers of last summer concerning the relief which has 
come to the vine-growing industry of France through the use of Amer- 
ican stock upon which to graft the European vine. 
Pasteur says: ‘‘I have often heard our wine-growers praise the American vines.” 
Senator Meinadier says: ‘‘My department, the Gard, was the first invaded by 
the Phylloxera. We had 93,000 hectares of vineyard, of which only one-eighth 
escaped. To-day we have about 1,000 hectares treated by submersion, about 1,000 
by insecticides, and nearly 30,000 planted with American vines.” 
Dr. Menudier, Vice President cf the Department Phylloxera Committee, says: 
“Since 1889 the territory in the Department of the Lower Charente covered with 
American vines has nearly doubled.” 
In the department of which Marseilles is the capital that region planted with 
American vines equals that planted with French vines. A professor of agriculture
