The students and thinkers who had been gathering facts from us all this time, collating and relating them, and making inferences, laid the result of their labors before the council.
Little had we thought that our careful efforts at concealment had been so easily seen through, with never a word to show us that they saw.

They had followed up words of ours on the science of optics, asked innocent questions about glasses and the like, and were aware of the defective eyesight so common among us.
With the lightest touch, different women asking different questions at different times, and putting all our answers together like a picture puzzle, they had figured out a sort of skeleton chart as to the prevalence of disease among us.

Even more subtly with no show of horror or condemnation, they had gathered something--far from the truth, but something pretty clear--about poverty, vice, and crime.

They even had a goodly number of our dangers all itemized, from asking us about insurance and innocent things like that.
They were well posted as to the different races, beginning with their poison-arrow natives down below and widening out to the broad racial divisions we had told them about.

Never a shocked expression of the face or exclamation of revolt had warned us; they had been extracting the evidence without our knowing it all this time, and now were studying with the most devout earnestness the matter they had prepared.
The result was rather distressing to us.
