Bob took the glass the doctor handed to him, smiling.

“Good for a weary troubled old man, boy,” he said, “but it will kill you. Don’t touch—don’t touch—don’t touch.”

He nodded and went back into the consulting-room, to compose himself upon the couch for his evening sleep, which he took according to custom, and from which he awoke refreshed and ready to work for hours, late into the night, at his wearisome chimerical task, with which he grew more infatuated the more his reason suggested that his work was vain.

The boy began to whistle very softly as the doctor disappeared. Then he washed and wiped the glass, and put it back in its place ready for use. After this he threw himself upon the settee, took hold of his right leg with his left hand, by the ankle, dragged it up, and held it across his body rigidly as if it were a banjo, and began to strum imaginary strings with his right hand, while in a whisper he sang a song about a yaller gal somewhere in the south, with close-shut eyes and a long wide mouth, and so on, through seven verses, with a chorus to each, all of which seemed to afford him the greatest gratification, and which he supplemented by leaping up and going round the surgery, holding out the imaginary instrument for contributions.

These were acknowledged with proper darky grimaces and grins, and seemed to be so abundant that Bob returned to the settee, and this time played the bones with a couple of pair saved from a brisket of beef, but without making a sound.

Another collection and another silent solo, this time on the tambourine, which the boy pretended to beat with frantic energy, ending by going on tiptoe to peep through the keyhole, and satisfy himself that the doctor was in a deep sleep.

There was no doubt about that, so the boy’s hour or two of indulgence, on which he regularly counted, began.

He dashed at the settee, threw it open, stooped down to take something out, but rose again, closed the lid, and listened as if afraid of being caught.

Then shaking his head, he ran to the door, which opened into the lobby and then into the street, from which place he came, helping himself along by the wall to the settee, upon which he sank, and after lying down and laying his leg out carefully, he began to play double parts, that of surgeon and patient. For, after feeling the leg and shaking his head, he said to himself, “Ah, we’ll soon put that right, my man.”

Jumping up, he ran to a drawer, from, which he brought splints and bandages, trotted back to the settee, and with ghastly minuteness—the result of having been present at an accident, and studious readings of Dr Chartley’s books—he proceeded to set a serious compound fracture, assuring himself that he bore it like a man, and that he need not be under the least apprehension, for in such a healthy subject the joint would knit together before long, and he would be as strong as ever.
