Such profitable visits were rare.  For days the two pioneers of trade and progress would look on their empty courtyard in the vibrating brilliance of vertical sunshine.  Below the high bank, the silent river flowed on glittering and steady.  On the sands in the middle of the stream, hippos and alligators sunned themselves side by side.  And stretching away in all directions, surrounding the insignificant cleared spot of the trading post, immense forests, hiding fateful complications of fantastic life, lay in the eloquent silence of mute greatness.  The two men understood nothing, cared for nothing but for the passage of days that separated them from the steamer’s return.  Their predecessor had left some torn books.  They took up these wrecks of novels, and, as they had never read anything of the kind before, they were surprised and amused.  Then during long days there were interminable and silly discussions about plots and personages.  In the centre of Africa they made acquaintance of Richelieu and of d’Artagnan, of Hawk’s Eye and of Father Goriot, and of many other people.  All these imaginary personages became subjects for gossip as if they had been living friends.  They discounted their virtues, suspected their motives, decried their successes; were scandalized at their duplicity or were doubtful about their courage.  The accounts of crimes filled them with indignation, while tender or pathetic passages moved them deeply.  Carlier cleared his throat and said in a soldierly voice, “What nonsense!” Kayerts, his round eyes suffused with tears, his fat cheeks quivering, rubbed his bald head, and declared.  “This is a splendid book.  I had no idea there were such clever fellows in the world.”  They also found some old copies of a home paper.  That print discussed what it was pleased to call “Our Colonial Expansion” in high-flown language.  It spoke much of the rights and duties of civilization, of the sacredness of the civilizing work, and extolled the merits of those who went about bringing light, and faith and commerce to the dark places of the earth.  Carlier and Kayerts read, wondered, and began to think better of themselves.  Carlier said one evening, waving his hand about, “In a hundred years, there will be perhaps a town here.  Quays, and warehouses, and barracks, and—­and—­billiard-rooms.  Civilization, my boy, and virtue—­and all.  And then, chaps will read that two good fellows, Kayerts and Carlier, were the first civilized men to live in this very spot!” Kayerts nodded, “Yes, it is a consolation to think of that.”  They seemed to forget their dead predecessor; but, early one day, Carlier went out and replanted the cross firmly.  “It used to make me squint whenever I walked that way,” he explained to Kayerts over the morning coffee.  “It made me squint, leaning over so much.  So I just planted it upright.  And solid, I promise you!  I suspended myself with both hands to the cross-piece.  Not a move.  Oh, I did that properly.”
