EXPERIMENT STATION RECORD. 



pp. SDG-3DS). — A review nf the method of combating phylloxera by destroying all 

 vines attacked, disinfecting the ground with carbon bisnl])hi(l, and replanting with 

 American stocks. The apparatus and process of injecting the tluid into the ground 

 are described in detail. The Government is aiding iu the work of exterminating the 

 insects.

Bisulphid of carbon as an insecticide, J. B. Smith {Ent. News, 5 {1S94), No. 7, 

 pp. 221, 222). — Notes on treating the melon louse on musknielons, by placing an open 

 cup containing a drachm of the chemical at each hill, and covering the plant with 

 a large inverted bowl or wooden box, and leaving for one hour. In nearly every 

 case all the aphides were killed, and the method is recommended. 



Experiments -with bisulphid of carbon as an insecticide, G. Battaxciion {La

 against the Phylloxera gave very unfavorable results. It was effective only iu 

 exceedingly permeable soils, and theie merely temporarily.

FOODS— ANIMAL PRODUCTION. 



Hay from Norwegian grasses, F. H. Werenskiold and E. Sol- 

 berg {Tidslcr. norslce Landbr., 1 (IS!) I), pp. 190-198). — Analyses are 

 given of 39 samples of tiniotliy hay, 12 of tall meadow fescue, 3 of tall 

 oat grass, 6 of orchard grass, and 5 of meadow foxtail. The samples 

 were grown in different i)arts of oSTorway, and were properly identitied, 

 pure specimens. The average composition of the various samples was 

 as follows, all results having been calculated on basis of a uniform water 

 content of 15 per cent :
