Martin dared not gainsay his mother, so he took Jurka and Vaska with him and went into the neighbouring village to seek work. And there met him a rich farmer. "Whither art thou going?" said he. "I want to hire myself out as a day-labourer."--"Come to me then. I take labourers without any contract, but if thou serve me well for a year thou shalt not lose by it." Martin agreed, and for a whole year he worked for this farmer without ceasing. The time of payment came round. The farmer led Martin into the barn, showed him two full sacks, and said, "Take which thou wilt." Martin looked; in one of the sacks was riches, in the other sand, and he thought to himself, "That's not done without a reason; there's some trickery here. I'll take the sand; something will come of it no doubt." So Martin put the sack of sand on his back, and went to seek another place. He went on and on, and strayed into a dark and dreary wood. In the midst of the wood was a field, and on the field a fire was burning, and in the fire a maiden was sitting; and it was such a lovely maiden that it was a delight to look at her. And the Beauty said to him, "Martin the widow's son, if thou wishest to find happiness, save me. Extinguish this flame with the sand which thou hast gotten for thy faithful service."--"Well, really," thought Martin, "why should I go on dragging this load about on my shoulders? Far better to help a body with it." So he undid his sack and emptied all the sand on the fire. The fire immediately went out, but the lovely damsel turned into a serpent, bounded on to the bosom of the good youth, wound itself round his neck, and said, "Fear me not, Martin the widow's son. Go boldly into the land of Thrice-ten, into the underground realm where my dear father rules. Only mark this; he will offer thee lots of gold and silver and precious stones; thou, however, must take none of them, but beg him for the little ring off his little finger. That ring is no common ring; if thou move it from one hand to the other twelve young heroes will immediately appear, and whatever thou dost bid them do they will do it in a single night." Then the young man set out on his long, long journey, whether 'twere a long time or a short I know not, but at last he drew nigh to the kingdom of Thrice-ten, and came to a place where a huge stone lay across the way. Here the snake leaped from his neck, lit on the damp ground, and turned into the former lovely damsel. "Follow me," said she to Martin, and showed him a little hole beneath the stone. For a long time they went through this underground way, and came into a wide plain beneath the open sky; and in this plain a castle was built entirely of porphyry, with a roof of golden fish-scales, with sharp-pointed golden pinnacles. "That's where my father lives, the Tsar of this underground region," said the lovely damsel to Martin.
