Tlie barometric readings were fairly high and within a mode- 

 rate range until the latter days of the month, when there was a 

 sharp fall. The notable variations were from 30'20 inches on 

 the ^nd to 29-50 inches on the 8th ; then rising to 30'20 inches 

 on the 10th and 11th, afterwards falling to 29-40 inches on the 

 13th. The pressure gradually increased to 30'30 inches on the 

 24:th ; after which the sharp declension already alluded to 

 occurred, when tiie pressure fell to 29 '00 inches on the 30th. 



Although frost was registered on 15 days, the total amount 

 was only 61°. The cold, drying winds and the frequent frosts 

 tended to keep the temperature low. The average maximum 

 temperature was 44°. and the average minimum 32°. 



The absence of heavy rain is very notable, as only 1 "43 inches 

 were registered. The greatest fall for one day was 0*35 inch, on 

 the 21st. There were 19 dry days. The dryness of the month 

 is best exemplified by comparing the figures with those of March, 

 1903, when there were only two dry days, a rainfall of 8*31 

 inches, while on 13 da.ys the amount registered exceeded one 

 quarter of an inch (0-25). 



The frosts during the month were not of such severity as to 

 hinder outdoor operations ; consequently farmers and gardeners 

 were enabled to work their land under satisfactory conditions. 

 The cold dry weather, however, decidedly checked the forward 

 tendency of vegetation, and growth, on the whole, was later 

 than at same period of preceding year. Willows were in bloom 

 by the 15th, followed closely by Daphne Mezereum and Erica 

 carnea, while the Crocuses were at their best between the 10th 

 and 20th. 



April. — The month began with wet weather, and throughout 

 did not belie its reputation for showers, frequently accompanied 

 by high winds, notably on the 6th and 24th, which days were also 

 bitterly cold. The remarkable feature of the weather was that 

 few days were out-and-out wet. Much of the rain fell in the 

 evenings or early mornings. 



The character of the weather is fairly shown by the varied line 

 of atmo.spheric pressure, as indicated by the barometric readings, 

 which, however, do not exhibit very severe changes, as only two 

 are in any way notable. From the 1st to the 11th the range
