"The special appointments, Mr. Secretary, are duly approved, and are now on their way over from the White House."

Two minutes later, a messenger entered, handing a sealed envelope to the Secretary of the Navy.

Breaking the seal, Mr. Sanders drew forth three heavy, folded sheets of parchment.

"Here you are, Mr. Benson," resumed the Secretary, handing over one of the parchments. "This document confers upon you, for the time being, the rank, pay and command of a lieutenant, junior grade, in the United States Navy. You, Mr. Hastings, and you, Mr. Somers, will rank as ensigns under your special appointments."

Jack's head swam a bit as he thanked Mr. Sanders; then he started to glance over this marvelous document.

But the Secretary of the Navy now cut in, briskly:

"That is all, gentlemen. You know your instructions, in general, Lieutenant Benson. You will now go to my chief clerk, who will swear you into the service. He will also give you an order on a local tailor for the uniforms of your ranks. In one hour and twenty minutes your train starts south. On arrival at Norfolk you will report without an instant's delay at the Navy Yard. Aboard the 'Sudbury' you will receive all further instructions, wired from this Department. Good morning, gentlemen."

Then, indeed, things moved fast. At the desk of the chief clerk of the Navy Department the three budding naval officers stood with their right hands raised while the official at the other side of the desk administered to them the oath binding them to loyalty to the government and to obedience to all lawful orders of their superiors.

"And now, gentlemen," continued the chief clerk, "I will send for Ensign McGrath, who is on duty here, and present you to him. He will go with you to the tailor's, and will see that you are properly rushed to the train that you are to take. Remember, you are not to pay for your uniforms or equipment. The bill will be sent here."

Ensign McGrath looked sleepy, but proved to be a hustler. One of the Department's autos was out in the grounds, and into this McGrath bundled the three submarine boys. Five minutes later they were in the tailoring establishment, where a good many ready-made uniforms were kept for sale.
