Among his minor peculiarities are that he is careless as to his attire, unclean in his person, exceedingly absent-minded in his habits, and addicted to smoking a short briar pipe, which is seldom out of his mouth.
He has been upon several scientific expeditions in his youth (he was with Robertson in Papua), and the life of the camp and the canoe is nothing fresh to him.
Lord John Roxton has some points in common with Professor Summerlee, and others in which they are the very antithesis to each other.
He is twenty years younger, but has something of the same spare, scraggy physique.
As to his appearance, I have, as I recollect, described it in that portion of my narrative which I have left behind me in London.
He is exceedingly neat and prim in his ways, dresses always with great care in white drill suits and high brown mosquito-boots, and shaves at least once a day.
Like most men of action, he is laconic in speech, and sinks readily into his own thoughts, but he is always quick to answer a question or join in a conversation, talking in a queer, jerky, half-humorous fashion.
His knowledge of the world, and very especially of South America, is surprising, and he has a whole-hearted belief in the possibilities of our journey which is not to be dashed by the sneers of Professor Summerlee.
He has a gentle voice and a quiet manner, but behind his twinkling blue eyes there lurks a capacity for furious wrath and implacable resolution, the more dangerous because they are held in leash.
He spoke little of his own exploits in Brazil and Peru, but it was a revelation to me to find the excitement which was caused by his presence among the riverine natives, who looked upon him as their champion and protector.
The exploits of the Red Chief, as they called him, had become legends among them, but the real facts, as far as I could learn them, were amazing enough.
These were that Lord John had found himself some years before in that no-man's-land which is formed by the half-defined frontiers between Peru, Brazil, and Columbia.
In this great district the wild rubber tree flourishes, and has become, as in the Congo, a curse to the natives which can only be compared to their forced labor under the Spaniards upon the old silver mines of Darien.
A handful of villainous half-breeds dominated the country, armed such Indians as would support them, and turned the rest into slaves, terrorizing them with the most inhuman tortures in order to force them to gather the india-rubber, which was then floated down the river to Para.
Lord John Roxton expostulated on behalf of the wretched victims, and received nothing but threats and insults for his pains.
He then formally declared war against Pedro Lopez, the leader of the slave-drivers, enrolled a band of runaway slaves in his service, armed them, and conducted a campaign, which ended by his killing with his own hands the notorious half-breed and breaking down the system which he represented.
No wonder that the ginger-headed man with the silky voice and the free and easy manners was now looked upon with deep interest upon the banks of the great South American river, though the feelings he inspired were naturally mixed, since the gratitude of the natives was equaled by the resentment of those who desired to exploit them.
One useful result of his former experiences was that he could talk fluently in the Lingoa Geral, which is the peculiar talk, one-third Portuguese and two-thirds Indian, which is current all over Brazil.
I have said before that Lord John Roxton was a South Americomaniac.
He could not speak of that great country without ardor, and this ardor was infectious, for, ignorant as I was, he fixed my attention and stimulated my curiosity.
How I wish I could reproduce the glamour of his discourses, the peculiar mixture of accurate knowledge and of racy imagination which gave them their fascination, until even the Professor's cynical and sceptical smile would gradually vanish from his thin face as he listened.
He would tell the history of the mighty river so rapidly explored (for some of the first conquerors of Peru actually crossed the entire continent upon its waters), and yet so unknown in regard to all that lay behind its ever-changing banks.
"What is there?" he would cry, pointing to the north.
"Wood and marsh and unpenetrated jungle.
Who knows what it may shelter?
And there to the south?
A wilderness of swampy forest, where no white man has ever been.
The unknown is up against us on every side.
Outside the narrow lines of the rivers what does anyone know? Who will say what is possible in such a country?
Why should old man Challenger not be right?"
At which direct defiance the stubborn sneer would reappear upon Professor Summerlee's face, and he would sit, shaking his sardonic head in unsympathetic silence, behind the cloud of his briar-root pipe.
So much, for the moment, for my two white companions, whose characters and limitations will be further exposed, as surely as my own, as this narrative proceeds.
But already we have enrolled certain retainers who may play no small part in what is to come.
The first is a gigantic negro named Zambo, who is a black Hercules, as willing as any horse, and about as intelligent.
Him we enlisted at Para, on the recommendation of the steamship company, on whose vessels he had learned to speak a halting English.
It was at Para also that we engaged Gomez and Manuel, two half-breeds from up the river, just come down with a cargo of redwood.
They were swarthy fellows, bearded and fierce, as active and wiry as panthers.
Both of them had spent their lives in those upper waters of the Amazon which we were about to explore, and it was this recommendation which had caused Lord John to engage them.
One of them, Gomez, had the further advantage that he could speak excellent English.
These men were willing to act as our personal servants, to cook, to row, or to make themselves useful in any way at a payment of fifteen dollars a month.
Besides these, we had engaged three Mojo Indians from Bolivia, who are the most skilful at fishing and boat work of all the river tribes.
The chief of these we called Mojo, after his tribe, and the others are known as Jose and Fernando.
Three white men, then, two half-breeds, one negro, and three Indians made up the personnel of the little expedition which lay waiting for its instructions at Manaos before starting upon its singular quest.
At last, after a weary week, the day had come and the hour.
I ask you to picture the shaded sitting-room of the Fazenda St. Ignatio, two miles inland from the town of Manaos.
Outside lay the yellow, brassy glare of the sunshine, with the shadows of the palm trees as black and definite as the trees themselves.
The air was calm, full of the eternal hum of insects, a tropical chorus of many octaves, from the deep drone of the bee to the high, keen pipe of the mosquito.
Beyond the veranda was a small cleared garden, bounded with cactus hedges and adorned with clumps of flowering shrubs, round which the great blue butterflies and the tiny humming-birds fluttered and darted in crescents of sparkling light.
Within we were seated round the cane table, on which lay a sealed envelope.
Inscribed upon it, in the jagged handwriting of Professor Challenger, were the words:—
