By my count, this is the fifth time travel story in the February 1959 issue of
F&
SF, which is a record. Maybe they were anticipating the release of
The
Time Machine in the subsequent year.
In this story, four orphans are sent to live in
the past with the rather odd Aunt Martha and the slightly less odd Aunt Harriet, who together
give the children only one commandment: Never play under the willow tree!
When the four O
::
children, Lucy, Robert, Charles, and May, were orphaned by a freak of circumstances, they
were sent to live in the Past with two spinster relatives, ostensibly because of crowded
conditions elsewhere.
