“I couldn’t say. All I know is that it’s one of the worst we have had in years. A trapper who arrived here yesterday from that region reported that it had destroyed the government telegraph line and had completely wiped out Jess Haldane’s trading post on Little Brush Creek.”

“Little Brush Creek!” Sandy frowned at the information. “Why, that’s only about twenty miles south of the trail we propose to take now—the one to Fort Vermilion.”

“No,” said Dick, turning to his chum. “It’s farther than that. I’d call it a good fifty miles.”

“Well, have your own way. But what’s fifty miles to a fire like that? By the time we get there, it may be raging not only south but north of the trail as well. You can’t deny it.”

“It’s quite possible,” Dick agreed.

“True enough,” appended Nesbitt. “I’m a little afraid that no matter which way you go, south to Peace River Crossing or west to Fort Vermilion, you stand a good chance of meeting the fire.”

“Tell you what we can do,” proposed Sandy. “We’ll strike out for the Peace, not west, but northwest of here and follow it up to Fort Vermilion.”

Dick and Nesbitt both laughed.

“Take us hundreds of miles out of our way and through a country almost impassable,” Dick objected. “Not a single trail to guide us. No, it would be foolish to attempt it. Our best plan is to follow the Vermilion trail and then, if necessary, circle around the fire.”

With considerable misgiving, they started out. Three days from Fort Bentley they made their way into an enveloping cloud of smoke, so thick and dark that at times it was almost impossible to see the sun. It formed a huge blanket which wrapped the earth. Hourly, it grew denser; breathing more difficult. It soon became apparent that they would be unable to get through. Turning to their right, they entered a densely wooded area, groping and gasping for breath. At times it was almost as dark as night. The smoke which settled around them was of a greenish tinge. It crept up the coulees and hollows in twisting snake-like form, while above the treetops swirled a heavy black cloud.
