In Japan the coolie rule is twenty minutes' rest every two hours. Their method of traveling is at a "dog trot," or long, swinging pace, which covers the ground with incredible swiftness. Mori's skill in selecting the karumayas soon became apparent, the distance to the destination being almost halved at the end of the first stretch.

The country through which the boys passed was flat and uninteresting, the narrow road stretching across a broad expanse of paddy fields, dotted with men, women and children knee-deep in the evil-smelling mud.

When a halt was called to rest and partake of refreshments, Mori accosted a native coolie, a number of whom surrounded the party, and asked if aught had been seen of a fiery-faced, red-whiskered foreigner clad in the heavy clothing of the coast.

The man eyed his questioner stupidly, and shook his head. The sight of a couple of copper sen, or cents, refreshed his memory. He had noticed a short, squat foreigner (called to-jin) in the interior. He was mounted upon a horse and had passed four hours before.

"Four hours?" echoed Mori, addressing Nattie. "Whew! he has a good start. And on a horse, too. That is the reason we could get no trace of him in the outskirts of Yowara. He must have left the train before it stopped and skipped into the brush, where he managed to secure a mount. He is certainly clever."

"But not enough to fool us," replied Nattie, complacently. "We will be hot on his trail before he reaches the caves."

After the customary rest of twenty minutes, the party resumed the road. As they proceeded the general contour of the country changed. The flat, plain-like fields gave way to rolling woodlands and scattered hills. The second hour brought them to the small village of Inawashiro.

Here was found a well-kept tea house, with spotless matted floor, two feet above the ground, a quaint roof, and the attendance of a dozen polite servants. Before the party had barely reached their resting place, the entire inhabitants, men, women and children, thronged about to feast their eyes upon a to-jin.

Inquiry developed the fact that Patrick had passed through the town not quite two hours before. This was cheering news. They were gaining on him. A brief lunch, and again to the road. Nattie and Mori examined their revolvers after leaving the village. Sumo cut a sapling in twain to prove his prowess.

At the end of the fourth mile a crossroad was reached. One, a broad, well-kept thoroughfare, led due north, while the other, apparently merely a path running over a hill in the distance, bore more to the westward. Mori called a halt.
