have to have the cooperation, not the enmity, of the Church in Lusitania.
And nothing spawned cooperation better than a common enemy.
It would certainly have been discovered eventually. The observation satellites that orbited Lusitania were feeding vast streams of data into the ansible reports that went to all the xenologers and xenobiologists in the Hundred Worlds. Amid that data was a subtle change in the grasslands to the northwest of the forest that abutted the town of Milagre. The native grass was steadily being replaced by a different plant. It was in an area where no human ever went, and piggies had also never gone there - at least during the first thirty-odd years since the satellites had been in place.
In fact, the satellites had observed that the piggies never left their forests except, periodically, for vicious wars between tribes. The particular tribes nearest Milagre had not been involved in any wars since the human colony was established. There was no reason, then, for them to have ventured out into the prairie. Yet the grassland nearest the Milagre tribal forest had changed, and so had the cabra herds: Cabra were clearly being diverted to the changed area of the prairie, and the herds emerging from that zone were seriously depleted in numbers and lighter in color. The inference, if someone noticed at all, would be clear: Some cabra were being butchered, and they all were being sheared.
Jane could not afford to wait the many human years it might take for some graduate student somewhere to notice the change. So she began to run analyses of the data herself, on dozens of computers used by xenobiologists who were studying Lusitania. She would leave the data in the air above an unused terminal, so a xenobiologist would find it upon coming to work - just as if someone else had been working on it and left it that way. She printed out some reports for a clever scientist to find. No one noticed, or if they did, no one really understood the implications of the raw information. Finally, she simply left an unsigned memorandum with one of her displays:
"Take a look at this! The piggies seem to have made a fad of agriculture."
The xenologer who found Jane's note never found out who left it, and after a short time he didn't bother trying to find out. Jane knew he was something of a thief, who put his name on a good deal of work that was done by others whose names had a way of dropping off sometime between the writing and the publication. Just the sort of scientist she needed, and he came through for her. Even so, he was not ambitious enough. He only offered his report as an ordinary scholarly paper, and to an obscure journal at that. Jane took the liberty of jacking it up to a high level of priority and distributing copies to several key people who would see the political implications. Always she accompanied it with an unsigned note:
"Take a look at this! Isn't piggy culture evolving awfully fast?"
Jane also rewrote the paper's final paragraph, so there could be no doubt of what it meant:
"The data admit of only one interpretation: The tribe of piggies nearest the human colony are now cultivating and harvesting high-protein grain, possibly a strain of amaranth. They are also herding, shearing, and butchering the cabra, and the photographic evidence suggests the slaughter takes place using projectile weapons. These activities, all previously unknown, began suddenly during the last eight years, and they have been accompanied by a rapid population increase. The fact that the amaranth, if the new plant is indeed that Earthborn grain, has provided a useful protein base for the piggies implies that it has been genetically altered to meet the piggies' metabolic needs. Also, since projectile weapons are not present among the humans of Lusitania, the piggies could not have teamed their use through observation. The inescapable conclusion is that the presently observed changes in piggy culture are the direct result of deliberate human intervention."
One of those who received this report and read Jane's clinching paragraph was Gobawa Ekumbo, the chairman of the Xenological Oversight Committee of the Starways Congress. Within an hour she had forwarded copies of Jane's paragraph - politicians would never understand the actual data - along with her terse conclusion:
"Recommendation: Immediate termination of Lusitania Colony."
There, thought Jane. That ought to stir things up a bit.
