TIDAL OBSERVATIONS. 
Annual report of the Engineer in charge of the Survey of Tides 
and Currents in Canadian Waters for the year 1899. In charge of W. 
Bell Dawson, C.E., F.R.S.C. :— 
The principal tidal stations have continued in operation; and nearly 
all of them have been visited during the season. One secondary tidal 
station has also been established this season at the outer end of Belle 
Isle Strait. Considerable progress has also been made in working out 
practical results from the tidal observations which have been secured. 
The last report, containing information as to the tides of the Bay of 
Fundy with observations on the tidal bore in the Petitcodiac River, has 
met with much appreciation. 
As the Survey becomes more widely known, the requests for infor- 
mation continue to increase. Many examples could be given of the 
accessory ways in which this Survey often proves of value, in addition 
to its direct service to the shipping interest. The tide-levels especially, 
which require to be carefully worked out for the reduction of the tidal 
observations themselves, have been of important service in connection 
with harbour works, in several instances during the past year. 
Tidal information has also been received from outside sources, with 
relation to the following places:—Moncton, N.B.; Shubenacadie River, 
N.S.; Chicoutimi; Annapolis, and Seymour Narrows, B.C. This in- 
formation consists of observations secured by tidal instruments loaned; 
observations of tidal currents; and bench marks establishing tidal levels; 
as explained in the Report of Progress. 
The total expenditure on this Survey during the fiscal year from 
June, 1898, to June, 1899, was $5,186.35. This includes, in addition to 
the ordinary fixed charges, the sum of $973.22 for the tidal observations 
in the Bay of Fundy in the summer of 1898; and $834.15 for repairs to 
the crib-work of the gauges at Forteau Bay and St. Paul Island. 
BAY OF FUNDY.—TIDAL DIFFERENCES. 
In the summer of 1898, eight secondary stations were established 
around the Bay of Fundy, in order to extend the usefulness of the tables 
for St. John, N.B., to the whole of this region. The extent of the region 
is 210 miles, from Yarmouth to Moncton.
