"They are like snakes after a full meal," said Cathie. "They've eaten too much, and it'll take 'em all their time to digest it."

Evans, however, had his doubts. He hinted to Blair that he feared an outbreak of sickness, but as yet could form no opinion as to its character. The men had lost all their energy, the women were depressed, the children listless. It was as though the strenuous doings at One-Tree Pass had sucked all the life out of them.

"It's come—I feared it, but could not be sure—smallpox."

"God help us! ... How has it got here?"

"Good God! How very horrible!"
