But all these experiences were beginning to have an effect. It was becoming a matter of course that Burl should give orders which others should obey. It was even becoming matter-of-fact that the possession of food was not a beautiful excuse to hide from all danger, eating and dozing until all the food was gone. Very gradually the tribe was developing the notion that the purpose of existence was not solely to escape awareness of peril, but to foresee and avoid it. They had no clear-cut notion of purpose as yet. They were simply outgrowing purposelessness. After a time they even looked about them with, dim stirrings of an attitude other than a desperate alertness for danger.
Humans from any other planet, surely, would have been astounded at the vistas of golden mushrooms stretching out in forests on either hand and the plains with flaking surfaces given every imaginable color by the moulds and rusts and tiny flowering yeasts growing upon them. They would have been amazed by the turgid pools the journeying tribe came upon, where the water was concealed by a thick layer of slime through which enormous bubbles of foul-smelling gas rose to enlarge to preposterous size before bursting abruptly.
Had they been as ill-armed as Burl's folk, though, visitors from other planets would have been at least as timorous. Lacking highly specialized knowledge of the ways of insects on this world even well-armed visitors would have been in greater danger.
But the tribe went on without a single casualty. They had fleeting glimpses of the white spokes of symmetrical spider-webs whose least thread no member of the tribe could break.
Their immunity from disaster--though in the midst of danger--gave them a certain all-too-human concentration upon discomfort. Lacking calamities, they noticed their discomforts and grew weary of continual traveling. A few of the men complained to Burl.
For answer, he pointed back along the way they had come. To the right a reddish dust-cloud was just settling, and to the rear rose another as they looked.
And on this day a thing happened which at once gave the complainers the rest they asked for, and proved the fatality of remaining where they were. A child ran aside from the path its elders were following. The ground here had taken on a brownish hue. As the child stirred up the surface mould with his feet, dust that had settled was raised up again. It was far too thin to have any visible color. But the child suddenly screamed, strangling. The mother ran frantically to snatch him up.
