ALLISON ON METEOROLOGY. 395 



noon — and clearing with wind veering W. in afternoon. On the 

 22nd we had snow in the morning. At 8 a. fine rain and sleet till 

 10.30 a ; and occasional sleet showers and snow squalls p. m. A 

 gale blew from S. E. early, and from S. W. to W. afternoon and 

 evening. On 23rd it still blew very hard from W. S. W. and W. 

 all day. Other phenomena were about their averages. 



March still kept rather low in pressure. Its temperature was 

 higher than usual, and presented a marked difference from the 

 abnormal deficiency of heat in March 1872; being as 30.^09 to 

 22.^91 ; nor did the Thermometer touch — which it does in this 

 month in two years out of three. The whole precipitation 4.09 

 inches was a. very little below the average, but the deficiency 

 happened both in rain and snow. Velocity of wind was much 

 increased, with a general N. W. direction. The aurora was observ- 

 ed seven times and fogs three. Three times the wind reached a 

 gale. On the 4th when, after nearly six inches of snow the pre- 

 ceding night with strong IST. E. wind, it backed and blew from 

 N. N. W. At 6h. 30m. of morning of 5th, the minimum thermo- 

 meter remstered 3.'^8. On the 21st we had snow and sleet in the 

 morning, and S. E. gale till 11 a., then heavy rain nearly all day. 

 Height of gale was at 9 a., when it blew 32 miles per hour. Wind 

 veered gently S. E. to S. W. between 6 and T p., but blew in S.W. 

 gusts during night. Barometer was lowest at 6 p. Last sleighing 

 on following day, on 22nd. On the 30th another gale was experi- 

 enced, but not so strong. The wind was hardest from S. S. E. at 

 2 a. = 22.5 miles per hour. It gradually fell till 4 a. when it 

 was quite moderate. The rain was heavy that morning from 1 to 

 5 a. Fog closed in from 9 to 10 a., and then the wind rose again 

 from S. to S. W., blowing strongly all day with rain and snow 

 squalls occasionally p.m. Cleared morning of 31st with W. breeze. 



The mean pressure of April was as close as possible to the nor- 

 mal of eleven years, being 29.724, or but one-thousandth part of 

 an inch below. The temperature also, 3 8.° 07, was most regular; 

 and only .05 below its normal. The N.W. wind still was in excess , 

 and the velocity 7.99 but very little less than that of March — the 

 most windy month of the year. But 1.93 inches of rain, which, 

 with a snow fall of 6.5 inches, gave a total melted of 2.86 inches.
