The figures in the tables are taken from the register kept by the Dock 
Master at Boston Dock. 
From the tables it will be seen that out of 2,822 tides recorded in the 
four years, 655, or about 23 per cent., were affected by the wind. Taking 
the yearly average number of tides affected as 163, 56, or 35 per cent., 
were increased ane to winds blowing from a northerly Gisecvica: or with 
the flood tide, and 62, or 38 per cent., were decreased by southerly winds 
blowing in the opposite direction to the tide, leaving about 27 per cent. 
affected by the winds in an opposite way to that which might have been 
expected. 
The number of tides raised by northerly winds is about the same as 
those depressed by southerly winds.
