"Now, hush up," warned Benson, suddenly. "Here comes Lieutenant Ulwin, who has undertaken to present us at the United Service Club. Idiots are barred from the club, you know, Eph."

By a great exercise of will power Eph managed to straighten his face by the time that the lieutenant overtook them. They entered a cab. By this time the young naval officers were beginning to understand that it is the usual custom to go about Washington in a carriage.

"Have you ever been at a Service Club before?" inquired their guide.

"We breakfasted at the club at Norfolk this morning?" Jack answered.

"Your acquaintance with our Service clubs is not very large, then?"

"We have also been at the club at Fort Craven."

"Oh!" smiled Lieutenant Ulwin. "I guess you gentlemen have been about a little more in the two branches of the service, than I had suspected. You have seen the officers of both the Army and the Navy at play?"

"Mostly at table, I should say," laughed Benson.

"The club is the only place where we can go and get away from shop-talk," continued Ulwin. "As a rule the Army and Navy men at our club do not talk much shop. It may be different to-day, however."

"Why to-day?" asked Jack.
