quay.

"May I go aboard?" he asked. "I hear that you carry a cargo of grain, and I'm anxious to see how it's loaded."

"Then you've come at the right moment, sir," was the answer. "Step right aboard, and look round as much as you want. We've been terrible hard at work these last two days getting a cargo of cotton ashore, and now we've just hove up the lower hatches, and shall be taking the grain out of her when dinner's finished. It's come all this way for your naval johnnies—at least that's what the boss has given me to understand; and we are expecting a party of officers along any moment to take a look at the stuff. I suppose they'll pass it right away, for it's good right down to the keel. Then these fellows will tackle it with shovels and bags, and you will see they'll hoist it up in a twinkling. Helloo! Blessed if that ain't the party coming along this way!"

He turned, and indicated his meaning by a nod of his head in the direction of three smartly-dressed naval officers who had just put in an appearance.

"The party right enough," he said. "Just excuse me, sir, and get right aboard if you care to."

Having obtained permission to go aboard, Tyler at once stepped to the gangway, and was quickly upon the deck. Then he went to the hatchway, which occupied a large square in the centre of the vessel, and leant over the combing so as to obtain a good view of the scene below. Beneath was a lower deck and a second hatchway of similar dimensions, the covering of which had evidently been recently removed. A glance showed him that the hold was filled with loose grain to within some six feet of the hatchway, and he was occupied in wondering how many sacks of corn had been necessary to fill it, when he was aroused by a voice at his elbow. Turning swiftly, he found the three naval officers and the mate standing beside him.

"A fine cargo, and in splendid condition," the latter was saying. "We've just hove up the hatches for your inspection, and that's the way down."

He pointed to a perpendicular ladder which led from the upper hatch to the one below, and stepped aside to allow the officers to approach it. At the same moment Tyler caught the eye of the elder of the three naval gentlemen, and at once, standing erect, he raised his hand as his father had long since taught him to do.

"Ah, the correct salute, and I thank you for it!" said the officer, acknowledging it swiftly. "Where did you learn it, my lad? I can see that you have been taught by someone who was no landsman."

"My father, Captain Richardson, late of the royal navy, instructed me, sir. He lives close at hand, and would spend his days here upon the docks were it not that he is crippled and cannot get about."

"By a gun-shot wound—obtained in warfare?" asked the officer with interest.

"Yes, sir. He was struck by a round-shot fired from a French fort, and was pensioned from the service."

"That is sad, very unfortunate," said the officer; "but his son must take his place, and repay the wound with interest when we have war with France again. But I must see to this cargo. This is one of the many duties which we sailors have to perform. At one time sailing a three-master, and then conning one of the new steam-vessels which have been added to our fleets. Another day we muster ashore, and then an officer can never say what he may find before him. He may have to visit the hospitals, the barracks, or inspect a delivery of hammocks before it is divided amongst the men. To-day we are here to see this cargo of grain, and to pass it if in good condition."

"Which it is, right away down to the keel, you guess!" burst in the American mate. "Say, sir, there's the ladder, and if you'll excuse me, the sooner the inspection's done with the sooner we'll clear the hold and get away out to sea."

"Then oblige me by slipping down, Mr. Maxwell, and you too, Mr. Troutbeck. Take one of those wooden spades with you, and turn the grain over in every direction. Be careful to see that it is not mildewed or affected by the damp. You can bring a specimen on deck for my benefit."

Hastily saluting, the two officers who had been addressed sprang towards the steep gangway which led below, and swarmed down it with an agility which was commendable. Then they paused for a moment or two upon the edge of the lower hatch until a wooden spade had been tossed to them, when they leapt upon the glistening mass of grain which filled the hold. Meanwhile Tyler and the officer who had remained above stood leaning over the upper hatch, looking down upon the figures below. Indeed, the former was fascinated, for the sight of a naval uniform filled him with delight, while to be able to watch officers at their work was a treat which he would not have missed for anything. It was queer to see the way in which the younger of the two juniors tossed his cane aside with a merry laugh and commenced to delve with the spade; and still more quaint to watch the second as he thrust his two hands into the corn, and, having withdrawn them filled to the brim, walked towards the edge of the hatch with the intention of spreading the grains there the better to inspect them. But—that was stranger still, for, missing his footing, the officer gave a violent swerve, and with difficulty saved himself from tumbling full length. The sight, the exclamation of astonishment and disgust, brought a smile to Tyler's lips; but a second later his expression changed to one of amazement. Why, the officer had again all but lost his footing, and—yes, as Tyler stared down at him, he staggered to one side, threw one hand up to his face, and then collapsed in a heap, where he lay with hands and toes half-buried in the corn. Almost at the same moment his companion, who had been digging vigorously, let his spade drop from his fingers, and looked about him as if dazed. Then he struggled towards his comrade with a low cry of alarm, only to stumble himself and come crashing into the grain.

"There's something wrong down there!" shouted Tyler, realizing that some terrible misfortune had suddenly and unexpectedly overtaken the naval officers. "Look, sir, they are on their faces, and appear to be insensible!"

He tugged at the sleeve of the senior officer without ceremony, and directed his attention to those below, for the former had been engaged in conversation with the mate, and had not witnessed what had happened.

"Something wrong!" he exclaimed in astonishment. "Why, what could be wrong? Ahoy, there, Troutbeck and Maxwell! Why, they are on their faces, and, as I live, they are insensible!"

His amazement was so great that he stood there dumbfounded, and stared at Tyler as though he could not believe his eyes. But a shout of alarm from the mate quickly aroused him.

"It's the gas!" he cried in shrill anxious tones. "Quick, or they'll be suffocated! Hi, for'ard there! All hands on deck to the rescue!"

He went racing towards the quarters in which the men were enjoying their meal, leaving Tyler and the naval officer alone. As for the latter, his astonishment was still so great that he remained rooted to the spot, leaning over the hatchway, the combing of which he grasped with both hands, whilst he stared down at the two prostrate figures huddled below upon the corn as though the sight was too much for him. Then he suddenly stood erect and screwed his knuckles into his eyes, as though he feared that they were misleading him.

"Gas!" he murmured doubtfully. "What gas? How could there be such a thing down there?" Then, suddenly recollecting the condition of his juniors, and realizing that they were in the gravest danger, he sprang towards the ladder which led to the hold below, and commenced to descend it as rapidly as possible.

But Tyler was before him, for though dumbfounded at first at
