Mephitic and Abominable

My skin grew cold, and my hair stood on end as I listened to that steady and ponderous footfall. There was some creature there, and surely by the speed of its advance, it was one which could see in the dark. I crouched low on my rock and tried to blend myself into it. The steps grew nearer still, then stopped, and presently I was aware of a loud lapping and gurgling. The creature was drinking at the stream. Then again there was silence, broken by a succession of long sniffs and snorts of tremendous volume and energy. Had it caught the scent of me? My own nostrils were filled by a low fetid odour, mephitic and abominable. Then I heard the steps again. They were on my side of the stream now. The stones rattled within a few yards of where I lay. Hardly daring to breathe, I crouched upon my rock. Then the steps drew away. I heard the splash as it returned across the river, and the sound died away into the distance in the direction from which it had come.
