Sari, lying slightly east of south, their return from the north took them over a different route from that which they had followed up from Korsar. Of course the Pellucidarians did not know these points of compass as north or south, and even David Innes carried them in his mind more in accordance with the Pellucidarian scheme than that with which he had been familiar upon the outer crust.
Naturally, with the sun always at zenith and with no stars and no moon and no planets, the Pellucidarians have been compelled to evolve a different system of indicating direction than that with which we are familiar. By instinct they know the direction in which their own country lies and each Pellucidarian reckons all directions from this base line, and he indicates other directions in a simple and ingenious manner.
Suppose you were from Sari and were traveling from the ice girt sea above Korsar to any point upon Pellucidar, you would set and maintain your course in this manner. Extend the fingers of your right hand and hold it in a horizontal position, palm down, directly in front of your body, your little finger pointing in the direction of Sari—a direction which you know by instinct—and your thumb pointing to the left directly at right angles to the line in which your little finger is pointing. Now spread your left hand in the same way and lower it on top of your right hand, so that the little finger of your left hand exactly covers the little finger of your right hand.
You will now see the fingers and thumbs of your two hands cover an arc of one hundred and eighty degrees.
Sari lies southeast of Korsar, while The Land of Awful Shadow lies due south. Therefore a Sarian pointing in the direction toward The Land of Awful Shadow would say that he was traveling two left fingers from Sari, since the middle finger of the left hand would be pointing about due south toward The Land of Awful Shadow. If he were going in the opposite direction, or north, he would merely add the word “back,” saying that he was traveling two left fingers back from Sari, so that by this plan every point of compass is roughly covered, and with sufficient accuracy for all the requirements of the primitive Pellucidarians. The fact that when one is traveling to the right of his established base line and indicates it by mentioning the fingers of his left hand might, at first, be deemed confusing, but, of course, having followed this system for ages, it is perfectly intelligible to the Pellucidarians.
When they reached a point at which the city of Korsar lay three right fingers back from Sari, they were, in reality, due east of the Korsar city. They were now in fertile, semi-tropical land teeming with animal life. The men were armed with pistols as well as spears, bows and arrows and knives; while Stellara and Gura carried light spears and knives, and seldom was there a march that did not witness an encounter with one or more of the savage beasts of the primeval forests, verdure clad hills or rolling plains across which their journey led them.
They long since had abandoned any apprehension of pursuit or capture by the Korsars and while they had skirted the distant hinterland claimed by Korsar and had encountered some of the natives upon one or two occasions, they had seen no member of the ruling class with the result that for the first time since they had fallen into the clutches of the enemy they felt a sense of unquestioned freedom. And though the other dangers that beset their way might appear appalling to one of the outer world, they had no such effect upon any one of the five, whose experiences of life had tended to make them wholly self-reliant, and, while constantly alert and watchful, unoppressed by the possibility of future calamity. When danger suddenly confronted them, they were ready to meet it. After it had passed they did not depress their spirits by anticipating the next encounter.
Ja and David were anxious to return to their mates, but Tanar and Stellara were supremely happy because they were together, and Gura was content merely to be near Tanar. Sometimes she recalled Balal, her brother, for he had been kind to her, but Scurv and Sloo and Dhung she tried to forget.
Thus they were proceeding, a happy and contented party, when, with the suddenness and unexpectedness of lightning out of a clear sky, disaster overwhelmed them.
They had been passing through a range of low, rocky hills and were descending a narrow gorge on the Sari side of the range when, turning the shoulder of a hill, they came face to face with a large party of Korsars, fully a hundred strong. The leaders saw and recognized them instantly and a shout of savage triumph that broke from their lips was taken up by all their fellows.
