A State in arms against a caterpillar, F. Osgood (Harper's Monthly Mag., 95 

 (1897), S<>- 567, pp. 458-465, figs. 4; rev. in Review of Reviews, 16 (1897), Xo. 91, pp. 

 $06, 207). 



Delarvation, 1'. Tertrix (L'Apiculteur, 41 (1897), Xo. .;, pp. 113-119). — The history 

 of the subject is hriefly reviewed and modern French legislation (law of 1888) and 

 processes noted. 



The destruction of the white grub, P. Tertrin (L'Apiculteur, 41 ( 1897), Xo. 4, pp. 

 165-168). — Among the remedies noted are crude naphthalin used at the rate of 400 gm. 

 for each square of 20 to 25 cm., benzin, and ammonia. 



Destruction of Luperus fiavipennis, Mexegaux and Cociiox (L'Apiculteur, 41 

 (1897), Xo. 4. pp. 164). — Besides Riley's formula for kerosene emulsion the following 

 of Yassiliire is given : Black soap, 2 kg. ; sodium carbonate, lkg.; petroleum, 1 liter, 

 and water, 100 liters. The mixture is prepared warm with 20 liters of water and 

 finally the rest of the water added. 



The employment of calcium carbid to destroy the phylloxera (L'Apiculteur, 

 41 (1897), Xo. 8, pp. 333-335). 



Hydrocyanic gas for greenhouse fumigation, P. H. Dorsett (Florixl*' Exchange, 

 9 (1897), Xo. 41, p. 915, figs. 2). — The advantages of the gas over other insecticides are 

 summarized and an improvement of the older methods of using it in greenhouses 

 suggested. This consists of a series of strings reaching to the door. To the inner 

 ends of these the potassium cyanid is suspended in paper bags (using two of the 

 bags to insure against one giving away on account of moisture gathered by the 

 cyanid before all is ready and thus endangering the life of the experimenter) over 

 dishes containing the necessary acid. When all is ready merely releasing the ends of 

 the strings near the door drops bags into the acid. His uearness to the door allows 

 the experimenter to escape. The method should not be useduuless the external tem- 

 perature is sufficiently high to allow of the houses being ventilated for as much as 

 30 minutes after the experiment. 



Notions about the spraying of trees, with remarks on the cankerworm, L. H.

 larvae, F. Y. Theobold (Entomologist, 30 (1897), No. 409, pp. 162-165, figs. 3).— It is 

 noted incidentally that experiments to infect other areas than those already infected 

 with the spores of the fungus have not thus far been very successful. 



An unlawful pursuit, T. G. Newman (Amer. Bee Jour., 37 (1897), No. 3, p. 36). — 

 In his report of the twelfth annual meeting of the National Bee Keepers" Union, the
