Then he ran to the boat, and came back with the stern and midship thwarts.

He drilled with his center-bit three rows of holes in these, two inches from the edge.
And now Helen's work came in; her grass rope bound the thwarts tight to the horizontal poles, leaving the disks room to play easily between the thwarts and the linchpins; but there was an open space thirteen inches broad between the thwarts; this space Hazel herring-boned over with some of Helen's rope drawn as tight as possible.

The cart was now made.

Time occupied in its production, three hours and forty minutes.
The coachmaker was very hot, and Helen asked him timidly whether he had not better rest and eat.

"No time for that," said he.
