Apparently he had no time to aim, or to think of aiming; he ducked a leaping rat, Bensington saw, and then smashed at the back of its head with the butt of his gun.

The monster gave one leap and fell over itself.
Cossar's form went right down out of sight among the reedy grass, and then he rose again, running towards another of the rats and whirling his gun overhead.

A faint shout came to Bensington's ears, and then he perceived the remaining two rats bolting divergently, and Cossar in pursuit towards the holes.
The whole thing was an affair of misty shadows; all three fighting monsters were exaggerated and made unreal by the delusive clearness of the light.

At moments Cossar was colossal, at moments invisible.

The rats flashed athwart the eye in sudden unexpected leaps, or ran with a movement of the feet so swift, they seemed to run on wheels.
