At first I was a complete duffer, and shamed myself in Colin's eyes.

But by-and-by I learned something of veld-craft: I learned how to follow spoor, how to allow for the wind, and stalk under cover.
Then, when a shot had crippled the beast, Colin was on its track like a flash to pull it down.

The dog had the nose of a retriever, the speed of a greyhound, and the strength of a bull-terrier.

I blessed the day when the wandering prospector had passed the store.
Colin slept at night at the foot of my bed, and it was he who led me to make an important discovery.

For I now became aware that I was being subjected to constant espionage.
