ALLISON— ON MEfEOROLOGr. T7 



fotce was extreme, never being equalled by any month that I 

 have recorded shice May 1857, either here or in Windsor. A 

 beautiful display of Aurora Borealis on the night of the 8th was 

 followed on the 9th by a high S.W. wind, rising to a gale about 

 5 p.m., and continued till midnight of 10th, at times blowing 

 very heavily, darting from S.W. to S. and back; finally settled 

 through W. to J^.W., and broke on the morning of 11th, when 

 the temperature which had been high fell quickly to only 

 5°. We had 11 days sleighing, but mostly bad. The mercury 

 was below on 2 days. A Lunar Halo on the 12th was followed 

 by mist, drizzle, and mild rain for the greater part of two days. 



March 1867 was rather clearer than usual ; but we had thre& 

 snow storms, besides considerable snow in other lighter falls,, 

 reaching altogether the great depth of 27.41 inches. Rain was 

 very scarce. The maximum tempefature, 50° 4 was low, and 

 the minimum high. The thermometer never marking below 

 6°, being a range of but 44". However, though extraordinary 

 cold was absent, a steady low temperature I'educed the mean of 

 the month to 26.94 which is over 1° below the mean of March 

 since 1863, and a figure seldom reached in this month. But one 

 day, the 27th, passed without frost. N.W. wind prevailed, 

 which is common in March, though scarcely more so than N. or 

 W. In this month the winds are very variable. The mean 

 force was again extreme ; only being equalled by last year, but 

 though the winds were brisk and strong almost continuall}^ they 

 never roise to gales. Gentle snow showers fell during a partial 

 eclipse of the moon on the night of 20th with alight W. breeze, 

 and during the day the wind passed slowly through N. to N.E. 

 There with some trifling viiriations, it remained till the night of 

 the 26th, the weather being dry during the whole period, when 

 rising very high from S.E. we had on the 27th a warm rain, 

 followed by a long succession of snow, and cold rain, in storms 

 and squalls, for many days. There was sleighing, generally 

 good, from 3rd to 21st, which was the last of the season. 

 Robins were seen near Windsor on the 23rd, but did not appear 

 generally in the open fields either there or here till the 5th of the 

 next month, or about the time that they are usually heard first. 

 Snow drops blossomed at Windsor on the 30th.
