"Or else they heard the noise ashore and put to sea," said Tredgold.
They stood gazing at each other in consternation. Then Stobell, who had been looking about him, gave vent to an astonished grunt and pointed to a boat drawn upon the beach nearly abreast of where their tent had been.
"Some of the crew have escaped ashore," said Mr. Chalk.
Striking inland, so as to get the shelter of the trees, they made their way cautiously towards the boat. Colour was lent to Mr. Chalk's surmise by the fact that it was fairly well laden with stores. As they got near they saw a couple of small casks which he thought contained water, an untidy pile of tinned provisions, and two or three bags of biscuit. The closest search failed to reveal any signs of men, and plucking up courage they walked boldly down to the boat and stood gazing stupidly at its contents.
The firearms which Stobell had pitched out of the tent the night before lay in the bottom, together with boxes of cartridges from the cabin, a couple of axes, and a pile of clothing, from the top of which Mr. Tredgold, with a sharp exclamation, snatched a somewhat torn coat and waistcoat. From the former he drew out a bulky pocketbook, and, opening it with trembling fingers, hastily inspected the contents.
"The map has gone!" he shouted.
The others stared at him.
"Brisket has gone off with the ship," he continued, with desperate calmness. "It was the crew of our own schooner that frightened us off last night."
Mr. Stobell, still staring in a stony fashion, nodded slowly; Mr. Chalk after an effort found his voice.
"They've gone off with the treasure," he said, slowly.
"Also," continued Tredgold, "this is not Bowers's Island. I can see it all now. They've only taken the map, and now they're off to the real island to get the treasure. It's as clear as daylight."
"Broad daylight," said Stobell, huskily. "But how did they know?"
"Somebody has been talking," said Tredgold, in a hard voice. "Somebody has been confiding in that honest, open-hearted sailor, Captain Brisket."
He turned as he spoke and gazed fixedly at the open-mouthed Chalk. In a slower fashion, but with no less venom, Mr. Stobell also bent his regards upon that amiable but erring man.
Mr. Chalk returned their gaze with something like defiance. Half an hour before he had expected to have been killed and eaten. He had passed a night of horror, expecting death every minute. Now he exulted in the blue sky, the line of white breakers crashing on the reef, and the sea sparkling in the sunshine; and he had not spent twenty-five years with Mrs. Chalk without acquiring some skill in the noble art of self-defence.
"Ah, Brisket was trying to pump me a week ago," he said, confidentially. "I see it all now."
The others glared at him luridly.
"He said that he had seen us through the skylight studying a paper," continued Mr. Chalk, shaking his head. "I thought at the time you were rather rash, Tredgold."
Mr. Tredgold choked and, meeting the fault-finding eye of Mr. Stobell, began to protest.
"The thing Brisket couldn't understand," said Chalk, gaining confidence as he proceeded, "was Stobell's behaviour. He said that he couldn't believe that a man who grumbled at the sea so much as he did could be sailing for pleasure."
Mr. Stobell glowered fiercely. "Why didn't you tell us before?" he demanded.
"I didn't attach any importance to it," said Mr. Chalk, truthfully. "I thought that it was just curiosity on Brisket's part. It surprised me that he had been observing you and Tredgold so closely; that was all."
"Pity you didn't tell us," exclaimed Tredgold, harshly. "We might have been prepared, then."
"You ought to have told us at once," said Stobell.
Mr. Chalk agreed. "I ought to have done so, perhaps," he said, slowly; "only I was afraid of hurting your feelings. As it is, we must make the best of it. It is no good grumbling at each other.
"If I had had the map instead of Tredgold, perhaps this wouldn't have happened."
"It was a crazy idea to keep it in your coat-pocket," said Stobell, scowling at Tredgold. "No doubt Brisket saw you put it back there the other night, guessed what it was, and laid his plans according."
"If it hadn't been for your grumbling it wouldn't have happened," retorted Tredgold, hotly. "That's what roused his suspicions in the first instance."
Mr. Chalk interposed. "It is no good you two quarrelling about it," he said, with kindly severity. "The mischief is done. Bear a hand with these stores, and then help me to fix the tent up again."
The others hesitated, and then without a word Mr. Stobell worked one of the casks out of the boat and began to roll it up the beach. The tent still lay where it had fallen, but the case of spades had disappeared. They raised the tent again and carried in the stores, after which Mr. Chalk, with the air of an old campaigner, made a small fire and prepared breakfast.
Day by day they scanned the sea for any signs of a sail, but in vain. Cocoa-nuts and a few birds shot by Mr. Stobell—who had been an expert at pigeon-shooting in his youth—together with a species of fish which Mr. Chalk pronounced to be edible a few hours after the others had partaken of it, furnished them with a welcome change of diet. In the smooth water inside the reef they pulled about in the boat, and, becoming bolder and more expert in the management of it, sometimes ventured outside. Mr. Stobell pronounced the life to be more monotonous than that on board ship, and once, in a moment of severe depression, induced by five days' heavy rain, spoke affectionately of Mrs. Stobell. To Mr. Chalk's reminder that the rain had enabled them to replenish their water supply he made a churlish rejoinder.
He passed his time in devising plans for the capture and punishment of Captain Brisket, and caused a serious misunderstanding by expressing his regret that that unscrupulous mariner had not rendered himself liable to the extreme penalty of the law by knocking Mr. Chalk on the head on the night of the attack. His belated explanation that he wished Mr. Chalk no harm was pronounced by that gentleman to be childish.
"We can do nothing to Brisket even if we escape from this place," said Tredgold, peremptorily.
"Do nothing?" roared Stobell. "Why not?"
"In the first place we sha'n't find him," said Tredgold. "After they have got the treasure they will get rid of the ship and disperse all over the world."
Mr. Stobell, with heavy sarcasm, said that once, many years before, he had heard of people called detectives.
"In the second place," continued Tredgold, "we can't explain. It wasn't our map, and, strictly speaking, we had no business with it. Even if we caught Brisket, we should have no legal claim to the treasure. And if you want to blurt out to all Binchester how we were tricked and frightened out of our lives by imitation savages, I don't."
"He stole our ship," growled Stobell, after a long pause. "We could have him for that."
"Mutiny on the high seas," added Chalk, with an important air.
"The whole story would have to come out," said Tredgold, sharply. "Verdict: served them right. Once we had got the treasure we could have given Captain Bowers his share, or more than his share, and it would have been all right. As it is, nobody must know that we went for it."
Mr. Stobell, unable to trust himself with speech, stumped fiercely up and down the beach.
"But it will all have to come out if we are rescued," objected Mr. Chalk.
"We can tell what story we like," said Tredgold. "We can say that the schooner went to pieces on a reef in the night; we got separated from the other boat and made our way here. We have got plenty of time to concoct a story, and there is nobody to contradict it."
Mr. Stobell brought up in front of him and frowned thoughtfully. "I suppose you're right," he said, slowly; "but if we ever get off this chicken-perch, and I run across him, let him look out, that's all."
To pass the time they built themselves a hut on the beach in a situation where it would stand the best chance of being seen by any chance vessel. At one corner stood a mast fashioned from a tree, and a flag, composed for the most part of shirts which Mr. Chalk thought his friends had done with, fluttered bravely in the breeze. It was designed to attract attention, and, so far as the bereaved Mr. Stobell was concerned, it certainly succeeded.
CHAPTER XX
Nearly a year had elapsed since the sailing of the Fair Emily, and Binchester, which had listened doubtfully to the tale of the treasure as revealed by Mr. William Russell, was still awaiting news of her fate. Cablegrams to Sydney only elicited the information that she had not been heard of, and the opinion became general that she had added but one more to the many mysteries of the sea.
Captain Bowers, familiar with many cases of ships long overdue which had reached home in safety, still hoped, but it was clear from the way in which Mrs. Chalk spoke of her husband and the saint-like qualities she attributed to him that she never expected to see him again. Mr. Stobell also appeared to his wife through tear-dimmed eyes as a person of great gentleness and infinite self-sacrifice.
"All the years we were married," she said one afternoon to Mrs. Chalk, who had been listening with growing impatience to an account of Mr. Stobell which that gentleman would have been the first to disclaim, "I never gave him a cross word. Nothing was too good for me; I only had to ask to have."
Mrs. Chalk couldn't help herself. "Why don't you ask, then?" she inquired.
