To buld a fire

From the text:

But all this - the mysterious, far-reaching hairline trail, the absence of sun from the sky, the tremendous cold, and the strangeness and weirdness of it all - made no impression on the man. It was not because he was long used to it. He was a new-comer in the land, a _chechaquo_, and this was his first winter. The trouble with him was that he was without imagination. He was quick and alert in the things of life, but only in the things, and not in the significances.
