Yamba told me that there would have been no help for us had we been overtaken on foot by these migratory rodents.

It is my opinion that no creature in Nature, from the elephant downwards, could have lived in that sea of rats.

I could not see the ground between them, so closely were they packed.

The only creatures that escaped them were birds.

The incessant squealing and the patter of their little feet made an extraordinary sound, comparable only to the sighing of the wind or the beat of a great rain-storm.
