PHENOMENA OF THE TIDES AT INDIANTOWN. 
By D. Leavitt Hutchinson, 
Director St. John Observatory. 
In the Autumn of 1907 a Richards recording tide gauge, 
with the necessary appliances and protection, was installed on 
the face of wharf adjoining the ferry slip at Indiantown. This 
type of gauge gives a continuous record of the tide from high 
to low and low to high, the curve being traced on a paper diagram 
placed on the cylinder which is revolved once every twenty- 
four hours by clockwork inside the cylinder. The pencil carrier, 
being connected by suitable gear, is moved up and down in 
accordance with the movement of the float. The diagrams used 
in these observations were scaled 0.50 of an inch to the foot. 
The purpose of installing this gauge was to determine the differ- 
ence in time of high and low water compared with the Kelvin 
recording tide gauge which the Tidal and Current Survey have 
had in operation at Reed’s Point, St. John Harbor, for many 
years, also to measure the tidal range at Indiantown. 
The following table is the result of nearly one month’s ob- 
servation, and shows by comparison the difference in time between 
high and low water at Indiantown and in St. John Harbor, 
also the range of tide at Indiantown.
