An express on the Long Island Railroad was tearing away at a wild and awe-inspiring rate of six miles an hour, when all of a sudden it stopped altogether. Most of the passengers did not notice the difference; but one of them happened to be somewhat anxious to reach his destination before old age claimed him for its own. He put his head through the window to find that the cause of the stop was a cow on the track. After a while they continued the journey for half an hour or so, and then - another stop.
"What's wrong now?" asked the impatient passenger of the conductor.
"A cow on the track."
"But I thought you drove it off."
"So we did," said the conductor, "but we caught up with it again."
