Douglas still felt terror-stricken when he was alone in the pool.
The remnants of the old terror would return, but he would rebuke it and
go for another length of the pool. He was still not satisfied. So, he
went to Lake Wentworth in New Hampshire, dived off a dock at Triggs
Island and swam two miles across the lake. He had his residual doubts.
So, he went to Meade Glacier, dived into Warm Lake and swam across to
the other shore and back.Thus, he made sure that he had conquered the
old terror.
