TABLE No. 9. Computation of Zj^for E-W axis, Lake Erie. 



In the fifth column there is shown the continuous summation of step 



D 3 



by step from the extreme eastern part of Lake Erie, near Buffalo, to the 



far side of the strip. The values of S shown in this fifth column were 



D 3 



obtained by adding successively the values of computed as shown in 



D 3 



table No. 8. For example, S-- for the west (or far) side of strip 1,200 to 



JD 3 



1,205 is shown as 185 in the fifth column of table No. 9. The value of 



D 3 



for strip 1,205 to 1,210 is shown as 5.00 in the last column of table No. 8. 



In the fifth column of table No. 9 the value of S for the west (or far) side 



D 3 



of strip 1,205 to 1,210 is shown as 190 (which is 185+5.00). 



Each value in the sixth column of table No. 9, called (6) for convenience, 



is the mean of the values of S at the two sides of the strip as shown in the 



D 3 



fifth column.
