APPENDIX C LXVII 
The network of stations equipped with these instruments has 
been augmented during the past year by the addition of 13 new stations 
in various portions of the world and the Committee of the British 
Association which has undertaken the discussion of results obtained, 
has now a wide field of observation and much valuable data is being 
obtained. It is intended within the ensuing year to supplement the 
Victoria equipment by the addition of several seismological instruments, 
which will enable Mr. F. N. Denison to continue his investigations 
under more favourable conditions. 
PHENOLOGICAL PHENOMENA, CANADA 1911. 
Of the phenological reports received for 1911, six are from British 
Columbia, five from Alberta, five from Saskatchewan, eight from 
Manitoba, seven from Ontario, two from Quebec, and averages for 
ten regions or belts in Nova Scotia. Of these, the latter, which are 
taken from a much larger list, and which were kindly supplied by Dr. 
A. H. Mackay, F.R.S.C., Superintendent of Education, Halifax, take 
first place in importance. The dates from which these averages are 
computed are chiefly collected by the school children under the guidance 
of their teachers, who forward the schedules to the inspector for the 
superintendent, by whom they are sent to a staff of phenologists, the final 
computation for 1911 for the various regions being made by Mr. J. B. 
Reid of the Educational Department. This practical use of nature 
study has now been carried on in Nova Scotia for many years under 
Dr. Mackay’s superintendence and it is to be hoped that similar work 
will soon be undertaken in other provinces. The climatic slopes or 
regions of Nova Scotia, which in any province could seldom be coter- 
minous with the boundaries of the counties, are subdivided into coast, 
low inland, and high inland belts. To obtain the averages ten or 
fewer good phenological observations are selected from those belonging 
to any given belt as shown in the tables. If there are not ten from 
each belt, two or if necessary three belts are combined, and the average 
so computed is the “region” phenochron. If a full sheet can be made 
out for each belt, the average of the phenochrons for the three “belts” 
will give the phenochron of the “region.” To find the phrenochron 
for each phenomenon for the province the phrenochrons of each of the 
ten regions are averaged. 
The reports received from other provinces are in most cases excel- 
lent and many observers evidently take great interest in the work. 
This gives great hope for the future and as several departments of
