There passed hour, and Dashkevich still did not come back. Professor Wagner lived near us, in only ten minutes of walking. It would be time to return to Dashkevich. I already began to worry. Also Pronin worried.

– A hard case – he told. – Wagner, obviously, finds it difficult to make the diagnosis. It is visible, our Kazya seriously ached…

At this time the frozen door awfully cracked, began to creak and opened. Puffs of vapor for a moment filled all room, and when they dissipated, we saw our friend who left a frosty cloud as Venus from sea foam. We attentively looked at each other: Dashkevich on us – with mysterious humour, we on it – interrogatively.

At last Pronin did not sustain and asked:

– Was?

Dashkevich with the same mysterious smile silently nodded.

– Cured?

Dashkevich did not answer. His face was very red, and he quickly and often breathed. Obviously, his fever amplified. Even it seemed to me that from it radiates with heat, as from our iron oven when it is heated.

– Perelechil me professor Wagner! – with laughter Dashkevich answered and quickly passed to the room.

– Nasty! – Pronin said in low tones. – If Wagner did not help, then Dashkevich not to survive…

We went deep into work. Suddenly the door from Dashkevich’s room opened and it left him, but… in what look! It was in a sports beskostyum. All red as if just took a steam bath in a bath to the seventh sweat, Dashkevich quickly passed through the room, without paying to us any attention, opened a door… and came to a forty-degree frost.

It was ridiculous, unexpected and terrible. Dashkevich’s act was equivalent to suicide. Several minutes it will freeze to itself (himself) hands and legs and will fatally chill lungs. Poor Kazya, he could make it only delirious! However that we sit? It is necessary to run to the aid, while the getting is good! I quickly rose and began to put on the fur-coat. For nervousness could not get a hand to a sleeve in any way. Pronin already put on and helped me.

– Rather, rather!

We ran out for a door.

There was a light moonlight night. From the house the road went down, to the small lake from which we took ourselves water. On this road we saw an extraordinary phenomenon.

On the road the huge sphere from puffs of vapor slowly slid. On a frost of couples turned into hoarfrost which made as if an external mobile cover of a sphere. Moonlight was reflected in the sparkling crystals of hoarfrost and gave iridescent auras. Behind a sphere the tail from snow flakes lasted. It was possible to think that on the road the small planetka who came on a silver platter together with the atmospheric attire slides. But we understood at once what the planetka is: the strange phenomenon left clear and quite deep prints of bare human feet on snow. It was our Kazya shrouded in a cloud of steam who brought down from his body excited with fever.

«Perhaps, this steam – I thought – protects Dashkevich’s body from burning action of cold a little, is perfect the same as the atmosphere protects Earth from action of absolute cold of interstellar depths. But whether for a long time his internal heat can be enough for Kaza? It will disappear from his body before Kazya reaches the lake».

– Казя! Казя! Stop! – we shouted, pursuing the cloud sliding on the road.

We could not consider Kazyu in this cloud of steam.

Dashkevich answered nothing to us, but quickened the pace. Small blizzards began to spin behind it. He already ran up to the coast of the lake, stepped into ice, stopped and suddenly desperately cried. Over the place where it stood, the whole column of steam rose. We ran on shout, entered dairy steam and is careful, blundered about to that place from where Dashkevich’s voice was heard. This voice reached from below.
