HARMONIC ANALYSIS AND PREDICTION OF TIDES 105 
columns are to be numbered consecutively, beginning with one (1) 
for the first day of the series. 
304. The series analyzed should be one of the lengths indicated in 
paragraph 152. Series of observations very nearly equal to one of 
these standard lengths may be completed by the use of extrapolated 
hourly heights. If the observations cover a period of several years, 
the analysis for each year may be made separately, a comparison of 
the results affording an excellent check on the work. 
305. The hourly heights on each page of form 362 are first summed 
horizontally and vertically. The total of the vertical sums must 
equal the total of the horizontal sums, and this page sum is entered in 
the lower right-hand corner of the page.
