 maps 2. — This is an account of observations made during a trip to tlie United 

 States and Canada during the summer and fall of 1907. The object of this trip 

 was to study the oi-ganization of the meteorological service, especially the 

 weather service, and the telegraphic and other methods of distributing infor- 

 mation about the weather in the United States, with a view to improving the 

 German weather service. The author states in conclusion that the organization 

 of the weather service in the United States may be taken as a model and that 

 its methods of distributing meteorological information, weather maps, and fore- 

 casts are the best in the world. He was particularly impressed with the rap- 

 idity with which the daily weather maps were prepared, printed, and dis- 

 tributed, and with the dissemination of the weather forecasts l)y means of 

 telegraph, telephone, and weather signals. 



Third annual report of the nieteorological committee (Ann. Rpt. Met. Com. 

 \Gt. Brit.^. .? ( li)OS). PI). Kl'i. pis. 5. fif/x. J). — This consists as usual of adminis- 

 trative reports regarding organization and operations (during the year ended 

 March 31, 1908) in marine meteorology, forecasts and storm warnings, clima- 

 tology, publication, investigation of the upper air (by AV. H. Dines), and miscel- 

 laneous subjects, with appendixes as follows : Report by the liquidator of the 

 meteorological council, supply of information to the public, lists of observers 

 who sent in " excellent " meteorological logs during the year and of logs and 

 flocuments received from ships, distribution of instruments, report on inspection 

 of meteorological stations, list of jiersons and institutions from whom publica- 

 tions and meteorologiciil data have been received and to whom publicMtions are 

 sent, and financial statement. 



The report calls attention particularly to jirogress ni;ide in the (irganizntion 

 of international cooperation during the year. 



During the year 1907 the percentage of complete success in the forecasts fcir 

 the whole of the British Isles was 54, of the sum of complete and pjirtial suc- 

 cesses 91, the average for 10 years 80..5. 



The daily normal temperature and the daily normal precipitation of the 

 United States, F. II. Rigelow iU. S. Dcpt. A(/i:. Wcatlicr Bur. Bui. /?, pp. 

 ISC)). — The results of the c.-ilculatiou to a uniform basis of the reliable available 

 data on temperature and precipitation in the United States are given in tabular 

 form in this bulletin. It is stated that "these tables of daily normal tempera- 

 ture and precipitation are imw in use in the climatological work of the Bureau 

 throughout the United State.s. and they have superseded all the daily normals 

 which were prepared several years ago from much less extensive data than were 

 availaltle in the formation of these tables." 



Monthly Weather Review {Mo. Weather Rer., .J.J (l!K)7). No. 13. pp. A7A + 

 <:i'7-616-\-19, pt.s. ,J/, rhart.s (>). — The reitort contains the usual summaries of 

 general climatic conditions with regard to pressure, temperature, precipitation, 

 relative humidity, climatological tables, tal)le of contents, index, etc., of the 

 Monthly Weather licview for 1907, and an api)endix containing the annual 

 report of the Chief of the Weather Bureau for the year ended June 30, 1907. 



The most notable abnormal meteorological features -of the year were the 

 wide fluctuations in the seasonal temperature, resulting in " the extreme warmth 

 of the latter part of March over the districts east of the Rocky Mountains, and 

 the continued cold attending the progress of the later sining and early sunnner 

 mouths over the greater part of the same districts. . . .
