METEOROLOGY. 259 



number of the special stations, or, in lieu thereof, a large number of 

 stations with self-registering apparatus, so located as to represent for 

 any country the greatest variety of typical altitudes, valleys, slopes, 

 summits, forests, shores, i)lains, &c. Climatic data from such statious 

 for ten years would answer any question bearing on auy new locality, in 

 addition to which are needed two or three temporary experimental fields 

 on which ten or twenty stations can be arranged. [The general weather 

 service of the Signal Office offering about two hundred stations, or about 

 one station to every 10,000 square miles, if it could be extended over 

 the whole world, would offer a fair basis for the general study of me- 

 teorology as a dynamic problem. It is only when we study the innu- 

 merable applications of this science to the wants of mankind that we 

 are confronted with the practical impossibility of securing enough sta- 

 tions and observations to satisfy all requirements. The best solution of 

 the difficulty seems to be the maintenance of first and second chiss sta- 

 tions for weather telegraphy and general storm study, and the main- 

 tenance of third-class and special stations to deal with the special 

 questions that are suggested by the meteorological student, as well as by 

 the various branches of human industry.] (D. 31. Z., i, p. 437.) 



2. [The progress of meteorology in America promises to be greatly 

 stimulated by the formation of state weather services, which will, it is 

 hoped, give for the respective states a detailed study of local climate 

 and its relations to agriculture and to human industry. These services 

 will also be the medium through which predictions of local thunder 

 storms, tornadoes, cold waves, &g., can be communicated to the people 

 in detail. The first organization of this kind dates from early in the 

 century, when New York, Penusjlvania, and possibly other states, 

 showed some activity in this direction. After a long period of neglect, 

 the subject was revived in 1875 by Professor Hinrichs, who started a 

 state service for Iowa, which has ever since been carried on most suc- 

 cessfully. The formation of additional services has been the direct re- 

 sult of a circular and other correspondence between General William B. 

 Hazen and the governors of the respective states. Similar services now 

 exist in some fifteen different states, some of which publish very excel- 

 lent monthly reviews, while others contribute their observations directly 

 to the Army Signal Ofiflce for use in its monthly weather review. It is 

 evident that in this way the study of meteorology and the utilization of 

 the work of the Signal Office will both be furthered, and that, on the 

 other hand, the general service, namelj', the prediction of general storms 

 and weather features, will be more especially fostered by the Signal 

 Service.] 



3. An important step for American meteorology has been the start- 

 ing of The American JNIeteorological Journal, a monthly review of 

 meteorological matters, edited by Prof. M. W. Harrington, of the Uni- 

 versity of Michigan, at Ann Arbor. The desirability of some such 

 journal has been for a long time felt, but the definite impulse to the
