"Well," said Smith finally, "as I said in the first place, I can't see how any other than the human form became supreme. As I understand biology--" "What gets me," interrupted Van Emmon; "what gets me is, WHY the humans have allowed such an infernal thing to happen!" Billie smiled somewhat sardonically. "I thought," she remarked, cuttingly, "that you were always in sympathy with the upper dog, Mr. Van Emmon!" "I am!" hotly. Then, with the memory of what he had just seen rushing back upon him: "I mean, I was until I saw--saw that--" He stopped, flushing deeply; and before he could collect himself Smith had broken in again: "I just happened to remember, doc; didn't you say that the Venusians, in those books of yours, say that Sanus is ruled by the workers?" "Just what I was wondering about," from Van Emmon. "The humans seem to do all the work, and the bees the bossing!" The doctor expected this. "The Venusians had our view-point--the view- point of people on the earth, when they said that the workers rule. We consider the bee as a great worker, don't we? 'As busy as a bee' you know. None of the so-called lower animals show greater industry." "You don't mean to say," demanded Smith, "that these Sanusian bees owe their position to the fact that they are, or were, such great workers?" Before the doctor could reply, Van Emmon broke in. It seemed as though his mind refused to get past this particular point. "Now, why the dickens have the humans allowed the bees to dominate them? Why?" "We'll have to go at this a little more systematically," remarked Kinney, "if we want to understand the situation. "In the first place, suppose we note a thing or two about conditions as we find them here on the earth. We, the humans, are accustomed to rank ourselves far above the rest. It is taken for granted. "Now, note this: the human supremacy was not always taken for granted." He paused to let it sink in. "Not always. There was a time in prehistoric days when man ranked no higher than others. I feel sure of this," he insisted, seeing that Smith was opposed to the idea; "and I think I know just what occurred to make man supreme." "What?" from Billie. "Never mind now. I rather imagine we shall learn more on this score as we go on with our work. "At any rate, we may be sure of this: whatever it was that caused man to become supreme on the earth, that condition is lacking on Sanus!" Van Emmon did not agree to this. "The condition may be there, doc, but there is some other factor which overbalances it; a factor such as is-- well, more favorable to the bees." The doctor looked around the circle. "What do you think? 'A factor more favorable to the bees.' Shall we let it go at that?" There was no remark, even from Smith; and the doctor went on:
