They had covered some hundreds of miles since leaving San Diego, and Jack, watching his map understood the time was close at hand for him to alter his course, and turn sharply toward the east, while the lighted mail line of travel continued northward.

Ten minutes afterwards and Perk again broke out.

“I kin see the fust wisps o’ that ere fog yeou was a tellin’ ’baout, boss,” he announced grimly, as though appreciating the flashing beacons more than before, now that they were about at the end of their string, with the whole world of mountainous ground facing them, so full of hidden snares and pitfalls, not to mention human tigers with a fierce vendetta against all those busybodies of their particular breed.

“That’s interesting news, but not so delightful, Perk, since I’m just going to switch, and head into the east.”

CHAPTER X
Battling with the Fog

Thanks to his carefully studied chart Jack knew just about when he must head into the east, and make for the disputed land, where fugitives from justice had long kept away from the long arm of the Law. In former days there had been just such a safe hiding-place further to the north, locally known as the “Hole in the wall;” but it was of the past, and for some years had been thrown open to settlers and tourists.

The die was cast, and for better or worse they had made their decision; but neither of them had any disposition to turn back. Danger and these men of the Force were accustomed to being familiar campmates; since there was no mission on which they could be sent but had its share of peril; if such expeditions were but picnics it would not be so necessary to dispatch the prize men of the Service on the track, where others had failed after shooting their bolt.

Speedily were they swallowed up in the night. Far distant, and in the east a mellow light low-down announced the rising of the moon, now far advanced in its last quarter. Jack did not count for any assistance in the rising of the uncrowned queen of the night, since already he could see the gathering fog was growing thicker every passing minute.

Several times he lost the remnant of moon entirely, to have it creep into view again, as though the thick vapor had temporarily opened up; but only to close in again worse than ever, until the glimpse of the climbing orb came no more.

Thus began their fight with the fog—its insidious influence seemed to shut them in like an opaque curtain, growing more and more dense as the minutes moved along.
