"The eyes of the world are upon you."

A few minutes later the Captain and the executive officers are upon the forward bridge, discussing the minor details of the plan of action, and casting apprehensive glances at the low line of black smoke on the eastern horizon.

The former is a fine-looking young officer, who has been rapidly advanced to commanding rank through his zeal and untiring labors to perfect the navy of his country.

Many an article from his pen on how a ship should be fought has been published in the scientific papers of America; but now he must put his theories to the test—to learn by experience, bitter or sweet, whether he merited the commendation which his numerous articles on naval science have won for him.

The Kearsarge, which was launched in 1900, is an armored cruiser of 9000 tons displacement, 420 feet in length, and 64 feet in breadth. The main battery consists of four 10-inch breech-loading rifles, firing projectiles weighing 500 pounds; two mounted in a 10-inch armored turret forward on midship line, and two in a similarly placed turret aft, and four 8-inch breech-loading rifles, firing projectiles weighing 250 pounds, mounted two each in a 6-inch armored turret on either beam.

The secondary battery consists of twelve 5-inch rapid-fire guns and eight 6-pounders mounted in armored sponsons on a covered gun-deck. On her superstructure rail, about 15 feet above the spar-deck, she carries twelve 37-millimeter revolver cannon and four long 1-pounders. With this tremendous battery she can hurl two tons of steel from one broadside of her main battery every minute, and 362 pounds of steel from her secondary broadside every five seconds. The velocity of this metal on striking within battle-range would be about twenty-five miles a minute. The heavy shells, if striking within the biting angle, can penetrate the armor of any war-vessel afloat.

On her berth-deck she carries five torpedo-tubes with two automobile Whitehead torpedoes for each tube. The charge used is sufficient to sink any cruiser afloat if exploded within ten yards of her bottom plating. The armor on her sides is 5 inches of steel, and her protective-deck is 3 inches in thickness.

Among the inventions which her Captain has given to his navy is a sound-detector, by means of which a sound can be magnified to a very great degree, and its direction accurately ascertained.

The Kearsarge had been fitted with one of these detectors before leaving the United States, for the Captain knew that many dense fogs would be met with off the English coast.

She has been cruising about in wait for her prey for over a week. The crew have been given incessant drill and sub-calibre target practice. The plan of attack has been discussed so often that it is known by all the officers.
