His face, bronzed by tropic suns, his curly yellow locks, his jauntily curled moustache, and a certain reckless gleam in his blue eyes, made him look like one of those dare-devil, Elizabethan seamen who thrashed the Dons on the Spanish Main. Man of action as he was, fertile in expedients, and constantly on the alert for possible dangers, Jack Duval was eminently fitted for the profession which he had chosen, and could only endure existence in the desert places of the world. This huge London, with its sombre skies, its hurrying crowds, its etiquette of civilisation, was by no means to his taste, and already he was looking forward with relief to the time when he would once more be on his way to the vivid, careless, dangerous life of the frontier.
Philip admired his friend's masculine thoroughness, and could not help comparing himself disadvantageously with the young engineer. Yet Cassim was no weakling of the boudoir; he also had sailed stormy seas, had dared the unknown where Nature fights doggedly with man for the preservation of her virgin solitudes. Still, withal, Jack was a finer man than he was. What were his luxurious travels, his antarctic explorations, in comparison with the actual hardships undergone by this dauntless pioneer of civilisation? Jack was one who did some good in the world; but as for himself – well, Philip did not care about pursuing the idea to its bitter end, as the sequence could hardly prove satisfactory to his self-love. He irritably threw away his cigarette, moved restlessly in his chair, and finally expressed himself in words.
"Why do you come here, Jack, and make us feel like wastrels? A few hours ago and I rather prided myself on myself; but now you make me feel idle, and lazy, and selfish, and effeminate. It's too bad of you, Jack."
Brains were not Duval's strong point, and, unable to understand the meaning of this outburst, he simply stared in vague astonishment at Sir Philip. Tim and the doctor, pausing in their conversation, pricked up their ears, while Cassim, paying no attention to this sudden enlargement of his audience, went on speaking, half peevishly, half good-humouredly.
"I am the enervated type of an effete civilisation. You, my friend, are the lusty young savage to whom the shaping of the future is given. You are Walt Whitman's tan-faced man, the incarnation of the dominating Anglo-Saxon race, ever pushing forward into fresh worlds. As compared with mine, your primæval life is absolutely perfect. The Sybarite quails before the clear glance of the child of Nature. Take me with you into the wilderness, John Duval. Teach me how to emulate the Last of the Mohicans. Make me as resourceful as Robinson Crusoe. I am a prematurely old man, Jack, and I wish to be a child once more."
"What the deuce are you driving at, Philip?" asked practical Jack.
"It's from a book he's writing," suggested Tim, with a laugh.
"Melancholia," hinted Peter, who was nothing if not medicinal.
Philip laughed and lighted a fresh cigarette. Duval ran his hand through his curly locks, pulled hard at his pipe, and delivered himself bluntly.
"I suppose all that balderdash means that you are tired of London."
"Very much so."
"Why, you never stay two days in London," said Peter, in astonishment.
"Neither do I. Don't I tell you I'm tired of it? Be quiet, Peter; I can see that Jack is on the verge of being delivered of a great idea."
"Upon my word, that's cute of you, Philip," exclaimed Jack, admiringly. "Yes, I have a scheme to propound, for the carrying out which I need your assistance – in fact, the assistance of all three."
"This promises to be an interesting conversation," said Cassim, in an animated tone. "Proceed, John Duval, Engineer. What is it you wish us to do?"
"I had better begin at the beginning, gentlemen all."
"That's generally considered the best way," observed Peter, with mild sarcasm.
"Be quiet! you small pill-box. Let Jack speak."
"As I told you at dinner," said Jack, placing his elbows backward on the mantelshelf, "I have been all over the world since I last saw your three faces. China, Peru, New Zealand, India, Turkey – I know all those places, and many others. I have made money; I have lost money; I have had ups and downs; but everywhere I can safely say I've had a good time."
"Same here," murmured Tim, refilling his pipe.
"At present I am in Central America," pursued Jack, taking no notice of the interpolation, "under engagement as a railway engineer to the Republic of Cholacaca."
"Cholacaca?" echoed Tim, loudly; "isn't it there the row's to take place?"
"Why, what do you know about it, Tim?"
"A special correspondent knows a lot of things," returned Fletcher, sagely. "Go on with the music, my boy. I'll tell you something when you've ended."
Jack looked hard at Tim and hesitated, but Philip, curled up luxuriously in his big chair, asked him to proceed.
"You're going to tell an Arabian Night story, Jack."
"Well, it sounds like one."
"Good! I love romance. It's something about buried cities, and Aztecs, and treasure, and the god Huitzilopochtli."
"Oh, bosh! You've been reading Prescott."
"It seems to me," observed Peter, plaintively, "that with all these interruptions we'll never hear the story."
"The first that speaks will be crushed," announced Tim, glaring around. "If you please, Mr. Duval, it's waiting we are."
Jack laughed, and resumed his story.
"While I was at Tlatonac – that is the capital of the Republic – I became mixed up in certain events, political and otherwise. I found I could do nothing I wanted to without assistance; so, as I suddenly remembered our promise to meet here this year, I came straight to London. In fact, I was in such a hurry to find out if you three had remembered the appointment, that I left my luggage at the railway station, and came on by a hansom to Portman Square. This is the reason I am not in evening dress."
"Oh, deuce take your evening dress," said Philip, irritably; "you might have come in a bathing-towel, for all I cared. I didn't want to see your clothes. I wanted to see you. Go on with the story of the buried city."
"How do you know my story is about a buried city?"
"I never heard a romance of Central America that wasn't."
"You'll hear one now, then. This isn't about a city – it's concerning a stone."
"A stone?" echoed his three listeners.
"Yes. An opal. A harlequin opal."
"And what is a harlequin opal, Jack?"
"Tim, I'm astonished at your ignorance. A special correspondent should know all things. A harlequin opal is one containing all the colours of the rainbow, and a few extra ones besides."
"Well, Jack, and this special opal?"
"It's one of the most magnificent jewels in the world."
"Have you seen it?"
Jack drew a long breath.
"Yes; once. Great Scott, what a gem! You fellows can't conceive its beauty. It is as large as a guinea-hen's egg. Milky white, and shooting rays of blue and green, and red and yellow like fireworks. It belonged to Montezuma."
"I thought those everlasting Aztecs would come in," said Philip smiling. "Well, Jack, and what about this stone?"
"Ah, that's a long story."
"What of that? The night's young, and the liquor's plentiful."
"I don't mind sitting up all night, if the story is interesting. Start at once Jack, and don't keep us any longer in suspense. I hate
