Old Unfaithful^

For an unknown reason, the famed geysers of Yellowstone Park in recent months have acted up. Eruption schedules have been disrupted. Old Faithful spat its steam to a record height of 223 ft. But according to a U. S. Department of Interior report last month (TIME, July 4), Old Faithful was still true to its name: it still blew off for five minutes every hour, like clockwork.

A subsequent report by Science Service disclosed last week, however, that even Old Faithful's schedule was no longer to be counted on. Once the geyser waited for 115 minutes between eruptions--its longest interval in 68 years.
