involved. The forest has come to life, become a sentient, functioning, thinking, mobile monster.

It is on the move, conquering, killing, destroying everything that stands in its way. Plants that were earth-bound by complicated root-systems are developing new forms and members, and becoming mobile. The larger forms, such as the ancient trees, in which such rapid evolution is impossible, are functioning as a supply house for the more quickly adaptable forms. The whole being becomes an army, backed by an alert, efficient industry, converting the chemical and nuclear treasure-house of Tihar into a formidable war machine.

This is a challenge which may not be denied. We must revise our whole approach to the colonization and re-civilizing of Venus, even our habits of thought. Plants, hitherto the docile or helpless servants of mankind, have become a deadly enemy and a threat to our very survival as a dominant life-form. Clouds of spores descended on the unsuspecting inhabitants with an effect similar to that of poison gas. A grull-cat hunter gives an account of being pursued by a variety of plants and wild animals, acting in concert as if directed by a master brain.

This is just a sample. More will come. If the mutation continues and spreads, even our domesticated plants and animals may turn and rend us like a pack of wolves. We are living on borrowed time, and some kind of decisive action must be taken.

Recent recordings taken by various weather stations indicate emanations of some unusual force within the forest as if power were being generated on a large scale. We now believe that these readings and the mutations are related. Authorities admit that it is believed--"

Hailard clicked off the switch, and gave orders to change the course to Castarona. His eyes met those of Torkeg Nasron and locked. Armored silence sprang between them. Nasron broke it.

"Does this mean that you are abandoning the attempt to rescue my daughter from this madman?"

Hailard shook his head sadly. "There is nothing we can do at the moment. We can accompany the suicide squads, perhaps learn something. From the broadcast, I surmise that Kial is dead. And Alston, too."

"You said the same thing about Annelle. We have reason...."

Hailard interrupted. "This situation is different. Worse. Annelle was living on borrowed time, even if she survived the wreck of the _Krajulla_. I feel much worse about Kial. I liked her. For that
