During February frost was registered on twenty 

 nights. Five degrees were recorded during tlie night 

 of the 1st, after which the mean temperature, both day 

 and night, was unusually high until the night of the 

 t)th, when it again fell to the freezing point. This 

 sudden rise of temperature Avas no doubt owing to 

 the earthquake which was felt here about 5 o'clock 

 on the morning of the 3rd. From the 10th to the 

 end of the month frost was more or less severe, the 

 lowest reading being on the night of the 15th, when 

 16* of frost were registered. Total frost, 88°. The 

 rainfall was exceedingly light this month. Vegetation 

 w^as in an advanced state during the early part of

 Tussilago, etc.,. were blooming away at their usual 

 season underneath the snow ; but vegetation gener- 

 ally was little in advance of what it was in the early 

 part of last month. 



During April the weather was very changeable, 

 with an unlimited supply of cold east and north-east 

 winds, but only a moderate rainfall. Frost was 

 registered on eleven nights; the lowest reading was 

 seven degrees during the night of the Stli. Total, 37°.
