In The Way Back, Khabarov buried some cloth in the snow in front of Janusz. Janusz even asked him why he is doing that. He replied: "you will see in the morning."
Next morning, Janusz removed the snow and checked the cloth, it filled with some ants or insects. Janusz has a smiling face after seeing this.
For what exact purpose did Khabarov bury the cloth in the snow?
