He strode on swiftly until he came to a small bluff.  Here he halted and threw himself full length upon the ground in a welcome shade.  He was within sight of the half-breed camp.  He shifted his position until his head was in the sun.  In this way he could see the scattered dwellings of the prairie outcasts.  Then he drew a small piece of looking-glass from his pocket and held it out in the sun.  Turning and twisting it in the direction of the camp, as might a child who wishes to dazzle a play-fellow’s eyes.  For several minutes he thus manipulated his impromptu heliograph.  Then, as he suddenly beheld an answering flash in the distance, he desisted, and returned the glass to his pocket.  Now he drew back in the shade and composed himself to smoke.

The half-closed eyes of the recumbent man gazed steadily out towards the camp.  He had nearly finished his third cigarette when his quick ears caught the sound of footsteps.  Instantly he sat up.  The steps grew louder and then round the sheltering bush came the thick-set form of Gautier.  He was accompanied by an evil-looking dog which growled sulkily as it espied the white man.

“Ugh!  Hot walkin’,” said the newcomer, by way of greeting.

“Not so hot as it’ll be to-night,” said the white man, quietly.  “Sit down.”

“More bonfires, boss?” said the half-breed, with a meaning grin, seating himself as he spoke.

“More bonfires.  See you, I want six of the boys at Lablache’s store to-night at eleven o’clock.  We are going to burn his place.  It will be quite easy.  Lablache will be away, and only his clerks on the premises.  The cellar underneath the building is lit by barred windows, two under the front, and two under the office at the back.  All you have to do is to break the glass of the window at the back and pour in a couple of gallons of coal oil.  Then push in some straw, and then light a piece of oil-soaked rope and drop it in.  The cellar is full of cases of goods and barrels of oil.  The fire will be unextinguishable.  Directly it is well lit see that the clerks are warned.  We want no lives lost.  You understand?  The stables are adjacent and will catch fire too.  I sha’n’t be there until later.  There will be no risk and lots of loot.  Savee?”

The cunning face of the half-breed was lit by an unholy grin.  He rubbed his hands with the unctuous anticipation of a shop-walker.  Truly, he thought, this white man was a man after his own heart.  He wagged his head in approval.

“Easy—­easy?  It is childlike,” he said in ecstasy.  “I have long thought of it, sure.  An’ thar is a big store of whisky thar, eh, boss?  Good—­good!  And what time will you come?”

“When the fire is lit.  I go to deal with Lablache.  Look you here, Gautier, you owe that man a grudge.  You would kill him but you don’t dare.  I may pay off that grudge for you.  Pay it by a means that is better than killing.”

“Torture,” grinned the half-breed.
