We spent hours every day working out our language difficulties. He learned so rapidly that I abandoned learning his language in favor of teaching him ours. Even such abstract concepts as time and space proved no obstacles. He grasped the purpose of my wristwatch after a single day's demonstration of its relationship to the passage of Sirius across the sky.
Using a pencil I had managed to convey our symbols for large numbers. Joe could count up to any number now, and he seemed actually to understand the open-end nature of our system of enumeration.
It made possible a mutual agreement on such matters as the number of "days" in a year, which he was mildly interested to learn numbered 440 on his planet. Then a startling piece of information came from him when I asked how long his people lived.
"Two years. Maybe three," he replied. Because of the shorter days, a Sirian year about equalled an Earth year, and I found it difficult to believe that these wonderful little animals lived only two or three years. He persisted until I believed him.
He was strangely vague when I tried to determine the common manner of death. Indeed, personal death was a concept either so hazy or distasteful to him that he refused to dwell on it. The most he would convey was that there were always new faces in the tribe, and the old faces rarely remained more than three years. At this time, he described himself as being more than a year old.
This was only one of several startling items that were revealed in our conversations. The golden people matured in three months to fully grown adults. A female could bear several babies a year and usually did. Yet Joe insisted that his tribe was the only clan on the face of the planet, so far as he knew, and that it numbered fewer than a thousand individuals.
There was no such thing as monogamy or even polygamy. True, at night when the air was cooler, they paired off, male and female, and each male chose from among several favorites. But there was no formal nor permanent mating arrangement.
Benson, who had set up a sheltered desk outside Joe's window in order to listen in with an anthropologist's avid interest, posed the question which grew into quite a mystery. Under such fruitful conditions and ideal environment, why hadn't Joe's people overrun the planet? Even with the brief life-span, each female should produce many babies.
Joe had no answer. The problem didn't interest him, and he refused to ponder it. He'd squat in the corner jealously guarding his limp-skinned mango, nipping at it occasionally when our questions failed to make sense.
We were all, incidentally, quite curious to taste Joe's tala juice, but it was his sole property. His lady-friends would hand it to no one but him, and he guarded it selfishly. Bailey and Sorenson had enlisted the help of our two organic chemists to examine the moist residue of the empty skins, but with their limited lab facilities all they could do was make guesses that the coveted juice was the product of fermentation or enzymic action with which we were unfamiliar.
