"Tchk!" the old man ejaculated, emitting a puff of white breath which the north-east wind from behind carried over the head of the nearest ox. "Put your shoulder to the wheel, Marco. Show yourself worthy of your name."

The boy obediently went round the cart and set his shoulder to the heavy wooden wheel on the off side. His grandfather shoving at the other, they helped the labouring oxen to drag the vehicle up the ascent, and then stopped to rest.

"That was well done, little son," said a woman of some thirty years, sitting in the forepart of the cart. She handed the boy a cake. Behind her the cart was piled high with bits of furniture and bundles of household gear. The boy seated himself on a rock and nibbled his cake. The oxen moved their heads about as if in search of provender. Straightening his tall form, the old man turned his back, and in the full blast of the bitter wind scanned the country to the north-east. A faint boom sounded far away in that direction. The woman started.

"Do you see anything, Father?" she asked, anxiously.

"Nothing, Nuta. But we must on. It will be two hours or more before we can call ourselves safe."

Smacking the heaving flank of the near-side ox, he set the beasts in motion, and the cart creaked and jolted on over the rough track. This was lightly covered with snow, which showed traces of those other travellers who in this December of 1915 had journeyed over the same route. Snow lay deeper in the hollows on either side, and on the heights in the distance. It was a bleak and desolate landscape, its rugged features somewhat softened, however, by the blanket of snow. Here and there dark patches stood out in the surrounding white, representing bushes or trees; but there was no house or cottage, no sign of life.

Old Marco, a small Serbian landed proprietor, had postponed his flight from before the invading Bulgars until all the other inhabitants of his village had departed. To the last he had hoped that the French and British forces would arrive in time to save him. His son was away fighting, as were all the men from the little estate. Having loaded all his portable possessions on to the cart, he waited with his daughter-in-law and grandson until the ever-approaching boom of guns warned him that further delay would mean ruin, and then set off southwards, to gain, if possible, protection from the Allied forces that were said to be retreating on Salonika.

The old man's pride was wounded. He traced his descent from that Marco Kralevich who, towards the end of the fourteenth century, struggled to maintain the independence of Serbia against the Turks, and whose name and knightly prowess live to-day in song and story. He had never tired of relating to young Marco the heroic deeds of his great ancestor, and it cut him to the heart that he was compelled, in the wreck of his country's fortunes, to abandon the homestead where he had kept alive the traditions of Serbian valour. Even now, old as he was, he would have borne a part in the national struggle but for the claims of his dear ones upon his protection.

The cart lumbered slowly on. From time to time the old man glanced anxiously behind, appealing to the boy--did he see anything moving there, or there? On one such occasion, when they stopped to rest themselves and the oxen, and the old man was looking to the rear, young Marco suddenly pricked up his ears, and stood intently listening.

"A strange sound, Grandfather," he said. "Where?"
