The Game of Jackstraws by Kate Douglas Wiggin

There was a roar of laughter at the old man's boast, but in a moment all was activity. The men ran hither and thither like ants, gathering their tools. There were some old-fashioned pick-poles, straight, heavy levers without any "dog," and there were modern pick-poles and peaveys, for every river has its favorite equipment in these things. There was no dynamite in those days to make the stubborn jams yield, and the dog-warp was in general use. Horses or oxen, sometimes a line of men, stood on the river-bank. A long rope was attached by means of a steel spike to one log after another, and it was dragged from the tangled mass. Sometimes, after unloading the top logs, those at the bottom would rise and make the task easier; sometimes the work would go on for hours with no perceptible progress, and Mr. Wiley would have opportunity to tell the bystanders of a "turrible jam" on the Kennebec that had cost the Lumber Company ten thousand dollars to break.

There would be great arguments on shore, among the villagers as well as among the experts, as to the particular log which might be a key to the position. The boss would study the problem from various standpoints, and the drivers themselves would pass from heated discussion into long consultations.
