« According to Mr. Binns, the tower is 97 feet 6 inches high, and the

 tenths; togetlier 157^ feet, or 1 foot more than by the above measure- 

 ments. Taking the mean, the church tower top will be 157 feet above 

 the canal, and 187 feet 4 inches (= 157+30-4) above the top of the 

 Breakwater Pole.
