Summaries of climatological data by sections {U. S. Dept. Agr., Weather 

 Bur. Bui. W, vols. 1, pp. [562], figs. 116; 2, pp. [508], figs. 99).— These are 

 bound sets of summaries first issued by Weather Bureau stations, volume 1 

 embracing sections 1 to 57, west of the Mississippi River, and volume 2, sections 

 58 to 106, east of the Mississippi River, each volume also containing a title page 

 and introduction. 



Meteorological observations, J. S. Stevens (Maine Sta. Bui. 208, pp. IfSl. 

 J/GS). — Observations at Orono, Ma, on temperature, precipitation, cloudiness, 

 and wind during 1912 are compared with the means of similar observations for 

 44 years. The mean temperature for 1912 was 42.68° F.. the mean for 44 years 

 42.-19° ; the precipitation for 1912 was 48.45 in., for 44 years 43.42 in. ; the snow- 

 fall for 1912, 46 in., for 44 years 90 in. ; the number of days on which there was 

 a precipitation of 0.01 in. or more was 102, the number of clear days 105, and 

 the number of cloudy days 99 ; and the total movement of wind in miles, 50,096. 



Meteorological observations at the Massachusetts Agricultural Experi- 

 ment Station, J. E. Ostbandee and H. W. Angieb (Massachusetts Sta. Met. 

 Bills. 291, 292, pp. Jf each). — Summaries of observations at Amherst, Mass., on 

 pressure, temperature, humidity, precipitation, wind, sunshine, cloudiness, and 

 casual phenomena during March and April, 1913. The data are briefly discussed 

 in general notes on the weather of each month. 



The relation between the precipitation over the watershed of the Ohio 

 River above and the stream flow at Cincinnati, J. W. Smith (U. S. Dept. 

 Agr., Weather Bur. Bid. 40, pp. 40, figs. Jf). — This subject is discussed on the 

 basis of observations on precipitation at seven stations and on river stage rec- 

 ords at Cincinnati during the 50 years from 1861 to 1910, inclusive. The con- 

 clusions reached are as follows : 



"(1) River stages at Cincinnati depend upon the precipitation over the whole 

 watershed above that city. (2) There has been a very slight decrease in flood 

 days in recent years, with the same rainfall. (3) The same amount of rainfall 

 causes a better flow of water in the river during the low-water period than 

 formerly. ' The number of low-water days was 14 per cent less during the past 

 25 years than during the preceding 25, calculating for the same rainfall. Dur- 

 ing the 10 years ending with 1910 the tendency for low water, vdth an equiva- 

 lent rainfall, was not so great as for any preceding 10-year period for the past 

 50 years. (4) Floods do not occur at Cincinnati during February and March
