The difficulty was to hoist it.

There were no holes in which to fix the parallel masts.

They would have to be held in position, as the breeze was stiffening, and it required all hands aloft.
At length, by superhuman exertions, the complex fabric was slowly hoisted to the perpendicular, looking very like a ladder, up which nine scarecrows were clambering.

However, no matter what it looked like now, as Wally predicted, they'd spank along.
"We're going already," gasped he, panting with the exertion of holding up his mast.

"Look out now! here's a nice breeze coming." He was right.
