PHENOMENA OF THE TIDES AT INDIANTOWN . 
49 
When the first of the tabulated records was made (October 
7th) the' high water reading on gauge was 5.90 feet; on the 
morning of the 9th, 6.70 feet; afternoon high of the same date, 
6.90 feet. This increase of water level was due entirely to a 
heavy fall of rain on the 8th, when 1.42 inches was recorded 
between 9 a. m. and 9 p. m. After that date there was a gradual 
decline in the water level, the last record of high water on 
November 1st registering 3.25 feet on the gauge. 
The comparisons show that the high water at Indiantown 
occurs, on an average, 1 hr. 6 m. later than the St. John Harbor 
high, and the low at Indiantown, on an average, 2 hr. 20 m. 
later. During the period under observation the minimum time 
of delay of high water at Indiantown was 0 hr. 45 m., the 
maximum 1 hr. 35 m. For the low tide, the minimum was 2 
hr. and the maximum 2 hr. 40 m. The average range was 1.30 
feet; the greatest range 1.73 feet and the least 0.65 feet. 
The Indiantown tide rises faster than it falls. On an average 
one hour and a quarter less time elapses from low to high water 
than between high and low water. This, possibly, to a less 
extent, is a phenomenon of all tidal rivers. While Indiantown 
is less than a mile distant from St. John Harbor, the rising tide 
must flow through the narrow gorge at the falls and reach the 
level of the basin above before its effect becomes noticeable 
on the Indiantown gauge. The tidal current continues running 
up river after high water and until mean water level has been 
reached with the falling tide. The ebbing current down stream 
continues flowing until the following high water in the Harbor 
has again brought the water to its mean level in the Indiantown 
basin. 
It is proposed that a more prolonged series of observations 
be made at Indiantown, if possible, beginning early in the spring 
and carried through the summer and autumn.
