 of electric lights, the purification of water, etc. The possibilities of the Cooper- 

 Hewitt mercury-vapor lamp are briefly referred to.

Report of the committee on rural engineering of the Association of Amer- 

 ican Agricultural Colleges and Experiment Stations, W. E. Stoxe et al. ( U. S. 

 Dep/t. Agr., Office of Experiment Stations Circ. 53, pp.10). — This report reviews the 

 present status of instruction and research in rural engineering in this country and 

 points out the necessity for improvement along these lines. It recommends the 

 creation of separate departments of rural engineering in the agricultural colleges 

 and commends the efforts of the Secretary of Agriculture to extend work of this 

 character in his Department. 



MISCELLANEOUS. 



Growth and management of American agriculture, F. T. Carlton (Ann. 

 Amer. Acad. Polit. and Sue. Sci., 22 (1903), Xo. 3, pp. 79-91). — A discussion based 

 upon the statistics of the last census. Attention is especially called to the following 

 conditions indicated by an analysis of these statistics: The readjustment and localiza- 

 tion of production as a result of better transportation facilities; and concentration of 

 population in cities and decline of small towns and villages, accompanied by unhealthy 

 unrest in the former and idleness in the latter. It is suggested that long-distance 

 transmission of electrical power Avill do much to remedy this condition by reviving 

 small industries and providing local markets. 



Improved educational facilities in the country, it is believed, will do much to check 

 the influx of rural population into the cities. The advantage of country training 

 over city training in developing the power of adaptability is pointed out, and it is 

 urged that rural schools should always keep in view the training of men and women 

 for farm duties.
