inches; February, 3 inches; March, 2 inches; April, 2 inches; December, 3? 

 inches. The last snow of spring was on April 15; the first autumn snow was 

 on October 27, not enough in the latter case to whiten the ground. The 

 annual amount of snow, as given above, is 4.90 inches above the average for 

 the five preceding years. 



FACE OF THE SKY. 



Average cloudiness of the year, 42.46 per cent, of the sky, which is 3.77 

 per cent less than the average. The number of clear days (less than one- 

 third cloudy) was 173; half-clear days (between one-third and two-thirds 

 cloudy), 91; cloudy days, 101. There were 37 days without a cloud, and 29 

 days without a trace of sky, 10 of the latter being in December. There was 

 not one entirely cloudy day from May 15 to November 1. August was the 

 clearest month — mean cloudiness, 23.87 per cent.; December was the cloudi- 

 est month, the mean being 61.50 per cent. The mean cloudiness at 7 A. M. 

 was 47.15 per cent.; at 2 p. m., 46.47 per cent.; at 9 p. m., 33.75 per cent. 



DIRECTION OF WIND. 



During the year (three observations daily), the wind was from the north- 

 west 261 times; southwest, 218 times; south, 153 times; southeast, 142 

 times; northeast, 105 times; north, 88 times; east, 72 times; west, 35 times; 

 calm, 21 times. The south winds (including southeast, south and southwest) 

 outnumbered the north winds (including northeast, north and northwest) in 

 the ratio of 513 to 4-')4. 



VELOCITY OF WIND. 



The number of miles traveled by the wind was 154,508. This gives a 

 mean daily velocity of 423.31 miles and a mean hourly velocity of 17.63 

 miles, the latter being 6.63 miles above the mean hourly velocity at Phila- 

 delphia. The position of the anemometer cups at an elevation of 105 feet 

 above the ground, the most elevated point for full fifty miles in all directions, 

 secures exposure to the full force of the wind. The maximum velocity was 

 attained June 27, when in 222 minutes the instrument registered 31 i miles, 

 or at the rate of 85 miles an hour. The greatest daily velocity was 1,502 

 miles, November 18. The strongest winds were in March, April and Novem- 

 ber; the lightest were in July and August. 



BAROMETER. 



Mean height of barometer column, 29.093 inches. Mean at 7 A. M., 29.114 

 inches; at 2 p. M., 29.071 inches; at 9 p. M., 29.093 inches. Maximum height, 

 29.727 inches, at 2 p. m., February 1; minimum, 28.533 inches, at 9 p. M. 

 April 3; yearly range, 1.194 inches. The highest monthly mean was in 

 December, 29.199 inches; the lowest was in May, 28.947 inches. The 

 barometer observations are corrected for temperature, but not for elevation, 

 in accordance with the rules of the Smithsonian Institution. 



RELATIVE HUMIDITY. 



Mean for the year, 64.06 ; at 7 A. m., 75.14; at 2 p. M., 45.77 ; at 9 p. m., 71.28.
