There appears to have been a general upward trend of the rate values throughout the whole series, to about September 7. There is here also a suggestion of a periodicity. Rains were frequent and plentiful until the latter part of the series of observations. Oxford, Ohio (fig. 8): Here there was a general increase in evapora- tion intensity throughout the season, until about August 31. The rates vary irregularly, from a minimum of 78 (week ending May 25) to a maximum of 249 (week ending August 3), the highest ones being nearly as great as those for San Diego. 1 Livingston 1907, 1.
