42 MONTHLY WEATHER REVIEW. JANUARY, 1919 requirements, and it is most likely that the fact that many people were unable to get in communication with this office tended to increase the excitement. The best means of meeting a situation of this kind is the issue of a short bulletin on the ordinary forecast card, which is given wide distribution in the city by mail carrier in the early morning delivery or in the afternoon, as conditions warrant. By multigraph process 2,000 or more of these bulletins can be prepared in a few minutes. In this way we have been able to reach the public more effectually than by telephone, and to do so several hours before the afternoon papers are issued. because of the short interval of time between rainfall and the resulting crest stage in the river, which is approsi- niately 12 hours in the upper and 18 hours in the lower stremi. This was most clearly brought out in July, 1915. A heavy rainstorm occurred over the watershed on July 7, most o$ the rain fallin between 8 p. ni. and midnight. miles above Dayton, about 11 a. m. of the Sth, and the river at Dayton had risen to within a foot of the highest stage by 2 p. m. of the Sth, although it continued to rise slowly till about midnight. It is exceedingly difficult to give timely warnin floods in a river the size and character of the h rl iami Of The crest stage from t fl is rain was reached at Piqua, 40 GEIPEBAL CLASSIFICATION OF METEOROLOGICAL LITEBATWE.
