"A cat-o'-mountain!" yelled Fred Hatfield, and as he shouted, the lithe cat sprang over the brush heap and landed in the road, right beside the timber cart.

Once Ruth had been into the menagerie of a traveling circus that had come to Darrowtown while her father was still alive. She had seen there a panther, and the wicked, graceful, writhing body of the beast had frightened her more than the bulk of the elephant or the roaring of the lion. This great cat, crouching close to the snow, its tail sweeping from side to side, all its muscles knotted for another spring, struck Ruth dumb and helpless.

Fortunately her gloved hands were locked about the timber on which she lay, for the next instant a third savage scream parted the bewhiskered lips of the catamount and on the heels of the cry the mules started at full gallop. The panther sprang into the air like a rubber ball. Had the mules not started the beast must have landed fairly upon the boy and the girl clinging to the reach of the timber wagon.

But providentially Ruth Fielding and her companion escaped this immediate catastrophe. The savage beast landed upon the wagon, however—far out upon the end of the timber, beyond the rear wheels. Mad with fright, the mules tore on along the wood road. There were many turns in it, and the deep ruts shook them about terrifically. Ruth and Fred barely retained their positions on the cart—nor was the catamount in better situation. It hung on with all its claws, yowling like the great Tom-cat it was.

On and on plunged the poor mules, sweating and fearful. Ruth and Fred Hatfield clung like mussels to a rock, while the panther bounded into the air, screeching and spitting, always catching the tail of the cart as it came down—afraid to leap off and likewise afraid to hang on.

The mules came to a hill. They were badly winded by now and their pace grew slower. The panther scratched along the reach nearer to the two human passengers, and Ruth saw its eyes blazing like huge carbuncles in the dusk. There was a fork of the roads at the foot of the hill. Fred Hatfield uttered a shriek of despair as the mules took the right hand road and struck into the bush itself—a narrow and treacherous track where the limbs of the trees threatened to brush all three passengers from the cart at any instant.

"Oh! oh! we're done for now!" yelled Fred. "They've taken the road to Rattlesnake Hill. We'll be killed as sure as fate!"

CHAPTER VIII

FIRST AT SNOW CAMP

Fred Hatfield's fears might have been well-founded had the mules not been so winded. They had run at least four miles from the railroad and even with the fear of the snarling panther behind them they could not continue much farther at this pace.
