^ The record of five days was missing and the month was taken at 28 days one- 
seventh being added to bring the amounts up for comparison with other years and 
other places. 
Note: The areas of the sheets at the Desert Laboratory and the Coastal Labora- 
tory are as 5 to 4 and hence data from the first-named place are to be multiplied by 
.8 to reduce to equivalent terms.
