Storms, storm tracks, and weather forecasting, F. H. Bigelow 

 (U. 8. Dept. Agr., Weather Bureau Bui. 20, pp.87, charts 20). — It is 

 stated that the purpose of this bulletin is "to present the latest 

 phases of the science of meteorology as regards practical forecasting 

 of weather conditions." It contains chapters, on the construction of 

 daily weather maps; weather forecasting by months, including discus- 

 sions of the origin and tracks of storms, frost formation, cold waves, 

 droughts, and other meteorological phenomena; weather conditions at 

 ^Yashington, D. C, for 26 years (1871-'96); circulation of the atmos- 

 phere in the upper levels — the international cloud observations ; descrip- 

 tion of the solar magnetic period of 20.68 days and its relation to the
