?In that condition, our old friend was bundled into a box on wheels, and made ready for his departure to the new life. Before going we all shook him by the paw, patted his head, and wished him a happy future, and, as he disappeared in the distance, there was a general expression of regret that we had seen the last of poor Tim. ‘Captain Dan’s’ lip trembled, and I feel sure if he had had it to do over again, he wouldn’t he done it.”
