whistle-belly vengeance

While East was making his toilet, Tom turned to the table, and made an assault on the bread and bacon, and then poured himself out a glass of beer and began to drink it, but was pulled up half way, and put it down with a face all drawn up into puckers by its sharpness.¶ "I thought you wouldn't appreciate the widow's tap," said East, watching him with a grin. "Regular whistle-belly vengeance, and no mistake! Here, I don't mind giving you some of my compound, though you don't deserve it."
