EXPERIMENT STATION RECORD. 



Meteorology, C. H. Pettee (JVew Hampshire Sta. Bui. 68, pp. 161f.^ 

 165, 168-192). — This gives brief notes on additions to equipment of the 

 meteorological department and on the weather of the year, and a 

 monthlj^ and annual summary for the period from July, 1898, to 

 June, 1899, inclusive, of observations at Durham, N. H., on tem- 

 perature, precipitation, cloudiness, and prevailing winds. The mean 

 temperature for the year was 45.9°, for 1 years ending June 30, 1899^ 

 ■45.8°; total precipitation for the year 43.6 in., average for 4 3'ears 45.5; 

 snowfall 82 in., average for 4 j^ears 67; number of da3^s on which 

 there was precipitation of 0.01 of an iiich during 1898 to 1899, lo7, 

 average for 4 years 105; prevailing direction of the wind, northwest; 

 clear days 114, partly cloud}' days 161, cloud}" days 80. 



"The last 3 months of the year [1898-99] were abnormally dry, with a total precip- 

 itation of only 3.6 in. Indeed this lack of rain was the chief feature of the weather 

 for the year, and had a marked effect upon farm crops, especially grass, the amount 

 of hay harvested in this vicinity being about one-half of that of the previous year. 

 Hoed crops on heavy soil did not suffer seriously." 



Meteorological summary for Ohio, 1898, C. A. Patton {Ohio 

 Sta. Bid. 109, pp. 37S-386). — Notes on the weather and tabulated 

 daily and monthl}' summaries of observations at the station on temper- 

 ature, precipitation, cloudiness, direction of the wind, etc., are given, 

 and for comparison similar data for previous years and for other parts 

 of the State. The following is a summary of results:
