 sugar industry of the world, the use of milk sugar, the methods of obtaining 

 and refining milk sugar, the machinery required therefor, the by-products of 

 milk sugar manufacture, and analyses of the ash of milk sugar and its by- 

 products. 



The oil of Douglas fir; a preliminary study of its composition and prop- 

 erties, II. K. Benson and M. Darrin {Jour. Iiidus. and Engin. Chcin., 3 (1911), 

 A'o. II, pp. 818-820). — The conclusion drawn from these tests is that not less 

 than one-third of fir oil consists of teii)ineol and that fir oil is so closely similar 

 to pine oil in its properties that it may be substituted for it in its commercial 

 ai)pllcation. It is pointed out that pine oil is beiug used very extensively as a 

 solvent for varnish gums in the cold, for rubber, for nitrocellulose lacquer, in 

 the manufacture of metal polishes, and for general use as an essential oil, and 

 that this market shotild be opeu in the future to fir oil. 



METEOROLOGY— WATER. 



A new service of agricultural meteorology in France, P. Klein (Vie Agr. 

 et Rurale, 1912, No. 7, pp. 169, 170; Internal. Innt. Agr. [Rome], Bui. Bur. Agr. 

 Intel, and Plant Diseases, 3 (1912), No. 3, pp. 607-609).— The service which is 

 now being established in France is described. This service will collaborate 

 with the general meteorological service established in 1S85. The new service 

 will be directeil by a central committee assisted by technical exi)crts. 



District stations will be centrally locate<^l in regions having similar meteoro- 

 logical conditions and will as far as possible be attached to scientific institu- 

 tions, such as observatories and schools of agriculture already existing. These 

 will act as centers for the distribution of forecasts and other meteorological 

 information of regional importance, as well as for the collection of data which 

 may be of importance to the central office. 



There will be numerous information and warning stations, also connected 

 where possible with local agricultural institutions. These will receive from 

 the regional stations and give out daily telegraphic reports and other informa- 

 tion concerning the principal weather conditions and advice regarding means 

 of protection against unfavorable conditions (storms, frosts, etc.). They will 

 in addition give particular attention to the study of the effect of varying 

 climatic factors on the development of plants and their parasites. 



Daily observations in agricultural as well as in pure meteorology will be 

 made at a large number of so-called agricultural posts attached both to the 

 district stations and to the information and warning stations.
