who can tell what the Suez Canal connects, it will be my turn to
pay for the dinner."

There was a silence following Grant's words while the Go Ahead
boys looked foolishly at one another. Not one of them was able to
answer the simple question.

"The Suez Canal," began Grant, "connects the Mediterranean Sea
with the Red Sea."

"How do you know?" demanded Fred. "You have never seen it."

"I don't have to see it to know. I have never seen London, but I
am quite confident there is a city by that name. By the way,
fellows, if you'll wait a minute I'll show you something I put in
my bag. I saved it for a day just like this."

Rising from his seat Grant hastily sought his bag and in a brief
time rejoined his companions.

"What's the matter?" demanded John, as he saw an expression of
consternation on the face of his friend.

"Matter!" retorted Grant. "Matter enough. Somebody brought the
wrong bag."

"Let me see," said John, rising and examining the bag, which
Grant had placed on the seat near him. "That's not mine."

"It surely isn't mine," said George.
