"Not under the ground, you silly! Come down and get the fiddle; I can't go in the sitting-room with my boots on."

So the violin was handed out, and poor Gem at last fell asleep, with a vague intention of being a good girl, and giving up the society of Tom and the B. B.'s forever.

About half past twelve Aunt Faith awoke; "I certainly hear music!" she thought. Opening the blinds she heard the faint strains of "Nelly Bly," with the well known "Hi," E flat; "Hi," E natural; "Hi," F natural, and at the same time saw a light proceeding mysteriously from the ground. Hastily dressing herself, she ran over to Tom's room; it was empty. Much disturbed, she knocked at Hugh's door; "Hugh! Hugh!" she called; "something is wrong. Please get up."

"What is it, Aunt Faith?" said a sleepy voice.

"Get up at once! Tom is gone; there is music somewhere, and the strangest light coming out of the ground in the back garden."

"The B. B.'s, I'll be bound," said Hugh with a laugh, as he threw on his clothes. "Don't be frightened, Aunt Faith; it's Ruin, Riot and Revenge."

"Dreadful!" murmured Aunt Faith outside the door.

By this time the whole household was awake, and a group of persons stole out of the back door and went down the garden walk. Finding a barricade of boards at the base of the hill, they opened it, and discovered a little den in the earth containing one chair, a table, the three dogs, and Tom; a candle stuck in a bottle gave light to the scene, and the table was covered with the remains of a feast, cake and pies having evidently once filled the empty dishes. Tom was playing dismally upon his violin, and the three dogs sat mournfully at his feet.

"Thomas, what does this mean?" said Aunt Faith severely.

Tom looked up and saw the extent of his audience. "It's just my underground shanty, Aunt Faith," he said dejectedly; "I've worked like a slave over it all day, and the B. B.'s agreed to sit up here all night and have lots of fun, so I climbed out of the back window and came down. But first they wanted things to eat, and I had to get 'em; and then, when they'd eaten up everything, they said if I didn't play they'd go home, so I had to get my fiddle. And I only knew one tune, and they got tired of it after a while, and a few minutes ago they all skedaddled and left me here alone with the dogs. However, I wasn't going to give it up, so I was just playing to amuse myself a little before daylight."
