in the spray, as is often the case, a slight advantage is gained by dissolving the 

 soap in the water before rather than after extraction of the nicotin." 



The other data reported upon are as to the keeping properties of tobacco ex- 

 tracts, the denaturing of tobacco, and field experiments on denaturing tobacco 

 intended for spraying purposes. The best denaturauts were found to be from 

 150 to 200 gal. of a 10 per cent copper solution and 50 gal. of turpentine per 

 acre, applied separately by spraying on the growing leaves. The use of turpen- 

 tine, however, would be impossible on a commercial scale owing to the high 

 price of the substance. 



Bibliography of the pulp and paper industries, H. E. Sueface (U. S. Dept. 

 Agr., Forest Serv. Bui. 123, pp. 48). — This bibliography of the pulp and paper 

 industries includes formal works and treatises, important pamphlets and re- 

 prints, and a number of works on cellulose, which do not bear directly upon 

 the pulp and paper-making industries. General reference works and periodicals 

 which do not deal specifically with pulp and paper, but print material from 

 time to time which is of importance to paper makers, are included in the ap- 

 pendix.

 are the results of analyzing musts and wines, a study of the distillation method 

 for determining the losses which occur under ordinary conditions, the use of 

 the von der Heide ether extraction apparatus for determining lactic acid in 

 wine, the fermentation of some musts with and without pure yeast, the isola- 

 tion and testing of some pure cultures of yeast, and the treatment of abnormal 

 wine with milk or charcoal.
