APPENDIX C LXXXIX 
SEISMOLOGY 
The Milne Seismographs at Toronto and Victoria have yielded 
some very interesting records. A Seismograph for registering the 
vertical component, recording on smoked paper has recently been 
installed at Victoria, and is working very satisfactorily. During 
the year the total number of disturbances recorded at Toronto was 
123 and at Victoria 129. Of this number, three were very large. 
Fourteen were of a more moderate character, and the remainder 
show trace amplitudes ranging from 0-1 to 2mm. Not only was the 
total number greater than that which we usually record, but from 
May 1st there was a marked increase in the intensity of the disturb- 
ances. The most important of the series occurred on September 
7th, October 3rd, and January 1st. The latter disturbance was one 
of the largest we ever recorded at Toronto. The earthquake centres 
were located respectively in Guatemala, Nevada, and in the South 
Pacific, the latter being submarine; possibly in the vicinity of the 
New Hebrides. The more moderate disturbances were recorded 
on May Ist; June 1st; July 31st; October 11th; November ist, 21st; 
December 12th, 31st; January 13th, 19th; February 1st, 6th, 20th, and 
27th. The majority were of submarine origin, the earthquake centre 
being in the vicinity of the Kurile Islands, Alaska, and off the coast 
of Central America. 
PHENOLOGICAL OBSERVATIONS, CANADA, 1915 
Mr. F. F. Payne of the Central Office of the Meteorological 
Service makes the following report on the Phenological Observations 
of 1915 :— 
“Of the phenological reports received five were from British 
Columbia, four from Alberta, nine from Saskatchewan, six from Mani- 
toba, six from Ontario, two from Quebec, and two from New Bruns- 
wick. The total number from these provinces shows a marked 
falling off in the interest displayed in past years, and this can only 
be accounted for by the distraction of the war. The averages for 
Nova Scotia are excellent as usual and are full of interest. In British 
Columbia vegetation was unusually forward in the spring, and these 
conditions, though less marked, were continued until the ripening of 
grain crops. In Alberta, Saskatchewan and Manitoba, the spring 
conditions were similar to conditions in British Columbia, but some- 
what later in the summer vegetation was retarded and the date of 
ripening of grain crops was later than in 1914. In Ontario, spring 
vegetation was generally earlier than the average, and although this 
was not so marked the ripening of grain was earlier than in 1914. In
