Dehan nodded unknowingly and splashed water onto his head. Another long word. Another speciality. There must be thousands, perhaps millions of them. +I am a historicollator+
+How interesting. I have always wanted to meet one+
Dehan closed both his eyes in the expression that meant humorous disbelief. +Can it be true? I have never met anyone other than another historicollator whoever heard of the speciality+
The other man rubbed his hairless scalp, now reddening under the sun, and smiled.
+I can pretend no great breadth of knowledge. I must admit that I searched the word out as a reference. In relation to my own work of course… +
At the mention of his work he suffered a natural embarrassment and Dehan sank beneath the water and swam in a circle to lessen it. There are certain things that are never discussed while bathing. +I should like to close my pores+ he said upon surfacing again. +And you?+
+A fine suggestion+ They waded ashore and quickly put on their robes.
+I have recently visited a frigidarium that is very unusual+ Linkica said hopefully, volunteering the information to excise the memory of his recent breach of conduct. He spoke the code number aloud, his fingers unconsciously tapping out the combinations of numerals in the air.
+I do not know it. I will be pleased to follow you+ Happier now Linkica moved quickly to the Door and activated it. Dehan stepped through behind him and his body recoiled as the subzero air and swirling snow struck at him, gasping at the sudden shock. They appeared to be on an icy ridge that fell away into snow-clouded nothingness on both sides. Ahead, barely visible through the pelting flakes, were two other Doors set into the cliff face. Linkica had to shout into Dehan's ear to be heard.
+When it is not snowing one can see impossibly far in this direction. Mountains, valleys, snowcap, terribly impressive+
+I shall… remember+ Dehan stammered through numb lips.
They shuffled across the slippery ice surface, following the groove worn by other footsteps, sharply aware that only a single waist-high bar on either side stood between them and plummeting destruction. Gratefully they passed through the Door and into a robing room and each took a cubicle. Dehan sent his soiled robe through a small Door back to his own quarters, then dried and put on a one-use lounge suit from the dispenser. His skin tingled and he felt wonderful. That was certainly a fine frigidarium. He would try it again, hopefully on a clear day.
Linkica was waiting for him at a table by the immense window. The light of twin moons flooded the valley outside, filling it with infinite shades of gray and black where hills, jungle, and river met and merged. Dehan knew this place, built into a high hillside of some tropical world. They nodded, ordered drinks, then sipped at them when they appeared on the table.
+What is your work?+ Dehan asked. +Phylogen- something you said+
+Phylogeneticist. I attempt to trace the origin of different species, ancestorship, relationships. Most useful in stockbreeding, food plants, that sort of thing+
Dehan nodded although he had no idea of what the man was talking about. Encouraged, Linkica went on.
+Some time ago I was consulted about a gene-linked human disease. I traced its origin and found the correction that must be made. Because of this I became most interested in mankind, this most unusual of all animals, and I began to trace our history. In some ways, one might say, there is a slight resemblance between my small labors and your great work. Are you working well of late?+
Dehan nodded and smiled. The man was goodmannered after all. One never discussed one's own work in detail until all present had mentioned theirs.
+I have done with the Elstaran. A tedious task, a portion of history that was singularly dull as human history goes, and entirely too long for its own worth. A dozen suns, twenty or so planets, now thankfully gone by courtesy of a fortuitous supernova. I reduced over nine hundred volumes to a single volume, losing nothing of value in so doing+
+Admirable. How we do need your sort of talent to pare the long ribbon of history to manageable units. We would drown in the superfluous were it not for you. I can state this truthfully, for in my own research I have realized for the first time the incredible length of the history of our species. Would you say millions of time units?+
+More. More+ Dehan spoke the words slowly, with deep feeling.
+That it could be so. I do believe it+ Linkica bowed his head beneath the weight of the thought. +A moment for beauty, if you will. Sunrise is near and the sky changes+
They watched silently for a brief time. The sky was lightening with a tropical swiftness. Mist rose from the trees and river and the first muted pink brought color to the grays, touching the swirls and pools with an invisible brush. It was entrancing and they opened themselves to appreciate it.
