"Sing, then."

"Will you lie still if I will?" asked Polly.

"It's a go!"

So Polly sang the old, old song of "The Drummer Boy of Waterloo," one that her grandmother had taught her when she was a wee girl.

The boy was true to his promise, and remained motionless until the last note ceased.

"Sing it again!" he commanded. "That's a dandy!"

Twice, three times more, the sad little ditty was sung; then the sweet voice slipped softly into Holland's "Lullaby," which had been learned from hearing it sung by Miss Lucy to restless little patients.

"Rockaby, lullaby, bees in the clover,
Crooning so drowsily, crying so low.
Rockaby, lullaby, dear little rover,
Down into wonderland,
Down to the underland,
Down into wonderland go!
"Rockaby, lullaby, dew on the clover!
Dew on the eyes that will sparkle at dawn.
Rockaby, lullaby, dear little rover,
Into the stilly world,
Into the lily world.
Into the lily world gone!"

"Rockaby, lullaby, bees in the clover,
Crooning so drowsily, crying so low.
Rockaby, lullaby, dear little rover,
Down into wonderland,
Down to the underland,
Down into wonderland go!
"Rockaby, lullaby, dew on the clover!
Dew on the eyes that will sparkle at dawn.
Rockaby, lullaby, dear little rover,
Into the stilly world,
Into the lily world.
Into the lily world gone!"

Before Polly reached the last word the song had died almost to a breath, for Burton was "gone"—fast asleep. For a time she watched him. His breathing was slow and steady. Finally she slipped softly from her chair, and glanced across the room. Miss Price nodded and smiled, and Polly tip-toed towards the door, beckoning her to follow.
