nine o'clock
We made the flag that night , by lantern light , out of Tish 's red silk petticoat . Hutchins was curious , I am sure ; but we explained nothing . And we fastened it obliquely over the river , like the one on the other side . Tish 's change of heart , which occurred the next morning , was due to a most unfortunate accident that happened to her at nine o'clock . Hutchins , who could swim like a duck , was teaching Tish to swim , and she was learning nicely . Tish had put a life-preserver on , with a clothes-line fastened to it , and Aggie was sitting on the bank holding the rope while she went through the various gestures . Having completed the lesson Hutchins went into the woods for red raspberries , leaving Tish still practicing in the water with Aggie holding the rope .
