“There comes Doctor Joe,” Andy announced, as Doctor Joe, walking up from the landing place, passed the window, singing in a rich tenor voice:

“The worst of my foes are worries and woes,

And all about troubles that never come true.

And all about troubles that never come true.

The worst of my foes are worries and woes,

And all about troubles that never come true.”

“I wonder, now,” said Thomas, “if ’taint true—that song Doctor Joe is singin’.”

Just then the door opened and in walked Doctor Joe himself.

“Always just in time!” he exclaimed.

“Set in! Set in!” said Thomas heartily, visibly cheered by Doctor Joe’s coming.
