A motor-car with the muffler cut out was approaching, at a most gratifyingly high speed.
The noise was as martial music to Lady.

The speed promised exhilarating sport.

Her trot merged into a headlong run; and she dashed out into the road.
The runabout was a bare fifty yards ahead of her, and it was coming on with a speed which shook even Lady's excitement-craving nerves.

Here, evidently, was a playmate which it would be safer to chase than to confront head-on.
It was at this juncture, by the way, that Lad lurched forward from the rear seat and that the Mistress pointed in terror at the endangered collie.
Lady, for once overawed by speed, leaped to one side of the road.

Not far, but leaving ample space for the driver to miss her by at least a yard.
