Perera took the matter seriously. He knew the local customs pretty thoroughly. "It is a personal question, you must know. It is revenge. And of course he is hurried by your leaving de country. None of de natives or half-breeds will interfere wid him very much--unless you make it wort deir while. If you come upon him suddenly, you might shoot him. But den he might shoot you. "Den dere's dis--infernal magic," said Perera. "Of course, I don't believe in it--superstition--but still it's not nice to tink dat wherever you are, dere is a black man, who spends a moonlight night now and den a-dancing about a fire to send you bad dreams.... Had any bad dreams?" "Rather," said Pollock. "I keep on seeing the beggar's head upside down grinning at me and showing all his teeth as he did in the hut, and coming close up to me, and then going ever so far off, and coming back. It's nothing to be afraid of, but somehow it simply paralyses me with terror in my sleep. Queer things--dreams. I know it's a dream all the time, and I can't wake up from it." "It's probably only fancy," said Perera. "Den my niggers say Porroh men can send snakes. Seen any snakes lately?" "Only one. I killed him this morning, on the floor near my hammock. Almost trod on him as I got up." "_Ah!_" said Perera, and then, reassuringly, "Of course it is a--coincidence. Still I would keep my eyes open. Den dere's pains in de bones." "I thought they were due to miasma," said Pollock. "Probably dey are. When did dey begin?" Then Pollock remembered that he first noticed them the night after the fight in the hut. "It's my opinion he don't want to kill you," said Perera--"at least not yet. I've heard deir idea is to scare and worry a man wid deir spells, and narrow misses, and rheumatic pains, and bad dreams, and all dat, until he's sick of life. Of course, it's all talk, you know. You mustn't worry about it.... But I wonder what he'll be up to next." "_I_ shall have to be up to something first," said Pollock, staring gloomily at the greasy cards that Perera was putting on the table. "It don't suit my dignity to be followed about, and shot at, and blighted in this way. I wonder if Porroh hokey-pokey upsets your luck at cards." He looked at Perera suspiciously. "Very likely it does," said Perera warmly, shuffling. "Dey are wonderful people." That afternoon Pollock killed two snakes in his hammock, and there was also an extraordinary increase in the number of red ants that swarmed over the place; and these annoyances put him in a fit temper to talk over business with a certain Mendi rough he had interviewed before. The Mendi rough showed Pollock a little iron dagger, and demonstrated where one struck in the neck, in a way that made Pollock shiver, and in return for certain considerations Pollock promised him a double-barrelled gun with an ornamental lock.
