What about the yellow machines that eat the earth and obble up the forest?

A cab driver's job is to drive people anywhere they want to go in big yellow machines called taxis.

To travel, each ticket had to be validated in a yellow machine on the platform.

The battered yellow machine lay on its side with oil pouring out of her, like blood from a heart-shot dinosaur.

The Daimler was parked outside the door, and a boy leaned against the front mudguard of the big yellow machine.

Above them all was an unidentified yellow machine labeled "improved."

The huge yellow machines began to sink downward and to move faster.

We found them near the walls of the glacier, crowded around a bright yellow machine that looked not unlike a large lawnmower.

Indeed, yellow machines were moving inside the building, on a platform that was rising by itself.

The yellow machines were getting their platform un- jammed.
