Then he made a big flat collar and a back-pad out of the leather in old boot-legs, and rigged a pair of tugs out of two pieces of rope.

Old Fred was quite cast down when he stood in harness between the shafts.
He had waited patiently to have his collar fitted; he had grinned and panted and wagged his tail with no suspicion of the serious and humiliating career he was entering upon.

Now he stood with a sober face and his aspect was full of meditation.
'You fightin' hound!' said Uncle Eb, 'I hope this'll improve yer character.' Fred tried to sit down when Uncle Eb tied a leading rope to his collar.
When he heard the wheels rattle and felt the pull of the wagon he looked back at it and growled a little and started to run.

Uncle Eb shouted 'whoa', and held him back, and then the dog got down on his belly and trembled until we patted his head and gave him a kind word.

He seemed to understand presently and came along with a steady stride.
