READY TO START

Characteristic it was of Tom Swift to act calmly in times of stress and danger, and he ran true to form now.Only for an instant did he show any sign of perturbation.Then with calmness and deliberation the young inventor quickly did a number of things to the controls within his reach.

First of all he signaled to the engine room that he was going to take charge of the boat.This meant that the navigator in the conning tower was to keep his hands off the various levers and wheel-valves.It was possible to operate the M.N.1 from three positions, but Tom wanted no triplicate handling of his craft now.

Almost the instant Tom signaled that he would take charge back came flashing the electrical signal from the conning tower that his orders were understood.The next thing that those aboard the craft became aware of was a tremor that seemed to run through the whole under-sea ship.The quiet had changed to a subdued humming, and the ominous lack of motion was succeeded by violent vibration.

"Backing her up, Tom?" asked Ned, in a low voice.

"Trying to," was the answer."But I'm afraid her nose has gone in pretty deep.I've reversed the propellers."For perhaps a minute this vibration continued, showing that the powerful electric motors were turning over the twin propellers at the blunt stern of the craft.But she did not change her position.

With a touch of his hand, and still almost as cool as the proverbial cucumber (though why they should be cool it is hard to say), Tom stopped the motors.Once again the craft was quiet, but now, instead of the occupants being able to see clearly from the thick, glass windows in the forward cabin, the water showed muddy and murky in the glare of the underwater searchlight.

"Bless my postage stamps, Tom! what has happened?" exclaimed Mr.Damon."Has a giant squid attacked us, as one did some time ago, and is he roiling up the water?""No, it isn't a squid, Mr.Damon," replied the young inventor easily; "though the water does look as if a squid had spilled a lot of his ink in it.This is just the effect of mud stirred up by our propellers.There may be more of it."Ned looked toward Mr.Hardley to see how he was taking it.The seeker after gold apparently had good control of his nerves, or else he was ignorant of what was going on.For he asked, casually enough:

"Have we stopped?"

"We have," answered Tom."I thought I'd give you a view of the scenery."Perhaps he spoke sarcastically, but, if he did, Mr.Damon's friend did not seem to be aware of it.Coolly enough he replied:

"Well, if this is a fair sample of underwater scenery I prefer something up above, though I appreciate that this may be needful.""We'll soon be traveling along," announced Tom."Koku," he added to the giant, who had been calmly sitting during the excitement, "go to the engine room and help with the big levers.""Yes, Master," was the answer.Koku had implicit faith in Tom.

Waiting a moment for his faithful servant to reach the post assigned to him, Tom again signaled to his helpers and then quickly turned a wheel which produced startling results.For all within the submarine suddenly slid forward across the cabin floor.

"Bless my hammock hooks, Tom! are you standing her on her head?" cried Mr.Damon.

"That's exactly what I'm doing," was the answer."I've started to empty one of the after ballast tanks, and that, naturally, raises the stern while the nose is held down."The submarine was indeed in a peculiar position.She was on a slant in the water, her nose held fast in the soft mud bank, and it was Tom's idea that by making the stern buoyant it might help to pull her free.

To this end he also gave what assistance the propellers were capable of adding by starting the motors again, so that the craft once more trembled and vibrated.

But it all seemed to no purpose.Aside from the slanting position, therewas no change in the M.N.1.Ned, looking out into the murky water, which had cleared slightly, saw that the craft was still held fast.And then, for the first time, Mr.Hardley seemed to become aware that something serious was the matter.Up to now he seemed to think that all that had occurred was done for the purpose of testing the newly outfitted underseas boat.
