work of the year. 



ocean forecasts and international cooperation. 



An important extension of the forecast work of tlie Bureau was 

 made during the year. By an arrangement with the secretary of the 

 meteorological office at London, England, the transmission by cable 

 from London to Washington of meteorological reports from certain 

 points in the British Isles and on the Continent of Europe, and from 

 Ponta Delgada, Azores, was begun December 18, 1900. These reports, 

 with observations from Nassau, Bermuda, and Turks Island, have 

 been regularly published on the daily weather maps issued at Wash- 

 ington, Baltimore, Philadelphia, New York, and Boston, together with 

 forecasts of the force and direction of the wind and the state of the 

 weather for the first three days out of steamers bound east from Ameri- 

 can ports. 



The Atlantic forecasts, which are based on the American, Atlantic, 

 and European telegraphic reports, were begun January 7, 1901, and 

 on June 1, 1901, they were made a part of the regular general night 

 forecasts issued at Washington. In a number of instances, when 

 storms of marked strength were passing eastward off the American 

 coast, forecasts were issued of the character of the weather which 

 would probably be experienced by steamers leaving European ports 

 westward bound, and by an arrangement with Lloyd's, of London, 

 these advices have been cabled to England. 



In addition to the daily forecasts of wind and weather and special 

 storm warnings, predictions of fog were issued when conditions favor- 

 able for fog development had been indicated in the steamer tracks 

 west of the fiftieth meridian. Reports from trans-Atlantic steam- 

 ships sliow that these forecasts and special warnings have been well 

 verified. 



In November, 1900, arrangements were made with Portugal to 

 receive reports from the meteorological observatory at Horta, in the 

 Azores. Observations are now regularly received by cable from that
