Are you going to sail on the ship ?" asked Bob politely.
"I expect to, if this is the right vessel.

I wish I was sure.
Perhaps you might be mistaken," and he glanced nervously around.
"No, I am positive.

There is Captain Spark now," he added as the commander came up a companionway.
"Oh, yes.

I shall speak to him." The nervous man started off.

Just then Captain Spark, having received his clearance papers by messenger, gave orders to cast off.
The _Eagle_ was about to sail.
"All ashore that's going ashore!" called the first mate.
The 'longshoreman started down the gangplank which was about to be hauled in.
"Wait, I must pay you!" called the nervous passenger, turning back toward the man who had brought his trunk aboard.
The 'longshoreman waited.
"Cast off that stern line!" shouted the captain.
"Oh, dear! I wish I was sure this was the _Eagle_!" spoke the nervous passenger.
"It is," Bob assured him, smiling at the man's manner.
