"Something wrong, Tzu?"

"I'm not sure, Commander, but it is definitely interesting. Do you see those rock formations there...and there?"

"The large rocks with the small ones clustered about?"

"That's right. Do you notice anything strange about them?"

I studied them for a few moments.

"They seem to have a similar configuration. Each one is a large rock surrounded by brush and small rocks. Why? Are they some kind of marker?"

"I'm not sure, but look at this."

She extended her arm to share her arm-unit.

"This is the same area, but displaying data from the last campaign. The formations are there, but a different number of them, and in different locations."

I compared the display on her arm-unit with the display on the View Screen. She was right. The configuration of the formations had definitely changed.

"Do you have similar data from the other two campaigns?" I asked.

She cued an index list and studied it.

"No data from the campaign against the Aquatics... They were concentrating on the bodies of water then...but...yes, here it is."

She fed a cue into the arm-unit and extended again. "This is the same area during the campaign against the Wasps."

Together we studied it. The rock formations on this display were arrayed differently from either of the others we had studied.

"Zur!"

"Yes, Commander."

"Take a look at this."

By the time he reached us, I had cued my arm-unit for the Leaper campaign display so we had all three examples in view.

"Look at these rock formations. They seem to be-"

"Commander!"

Mahz's voice beamed into my head, interrupting my discussion.

"Rahm here, Mahz."

"Coming onto your screen now! Request immediate instructions!"

"Commander!" Horc called.

"Coming! Tzu, Zur!"

We crowded around the View Screen. There, coming into view was a large anthill.

The Ants! The last members of the Coalition after the Leapers! We knew they would be present on this planet, but none of our data had indicated their activity in this area. The hill was a new installation, constructed since our last campaign. It was less than eight kilometers from our fortification!

CHAPTER FIVE

The discovery of the anthill understandably threw our team into a bit of a turmoil.

Word was passed to all team members as Alert status immediately went into effect. Mahz and Vahr, however, were ordered to finish their survey sweep as originally planned. Whatever our future plan would be, we would require information on the terrain around us.

Zur placed Kor in temporary command of the defense forces and joined the rest of the staff in our emergency planning session.

Tzu, speaking for the Scientists, had very strong opinions, not only on the subject at hand, but also on how it was to be discussed. I was beginning to expect this.

"But, Commander, the course of action we have to recommend is the only logical approach to this situation."

"Recommendations for courses of action and discussion of those recommendations will take place after we have had the necessary informational reports from the staff."

"If I might point out, Commander, time is of the utmost importance in this situation," she argued, her tail lashing impatiently.

"I agree. Far too important to waste arguing over meeting procedures."

"But-"

"And I will further point out that had we followed your initial time-sensitive recommendations and pursued the Leapers, without a mapping sweep, we would have either missed the anthill completely or blundered into it unawares. Now I will again suggest you give your portion of the information report and save your valuable recommendations for later."

"Very well, Commander. How detailed a report do you wish?"

"Summary only. As you have pointed out, time is of the essence. Address specifically those behavioral points pertinent to the immediate situation."

She was silent for a few moments, organizing her thoughts; then she began.

"The Ants are the fourth species of the Coalition of Insects. According to the notes of the First Ones, confirmed by our own studies, they are the most intelligent members of the Coalition and hence the most dangerous. They were rated as being the most responsive to training in the operation of simple mechanical devices, and possess a definite-ordered society. In all probability, they were the masterminds behind the initial formation of the Coalition."

"Question."

"Yes, Horc."

"Are they still operating machines, and if so, of what level complexity?"

"Unknown. They are credited with being able to pilot primitive starships after the First Ones modified the controls for them, and the continued spread of the Insects through the Universe indicates some machinery is still being utilized. However, whether these are the original ships or if improvements have been made is unknown. This is why the Scientists recommend that we-"

She broke off as I caught her eye and flattened my head. For a moment she held my gaze, then continued.

"Although they will forage for food on the surface of the land, they are primarily burrowing creatures. The bulk of their civilization is maintained in subterranean caves and caverns interconnected by a series of tunnels. These colony nests may extend over a radius of up to twenty kilometers with installations to a depth of two kilometers.

"Physically, they are a bit larger than the Leapers, often reaching five meters in length. Even though it might be suspected they have poor eyesight from their underground existence, they seem to forage on the surface both day and night. Their primary natural weapon is a set of powerful mandibles, and they are reputed to be strong, vicious, and tenacious fighters."

"You mentioned a civilization," I inserted. "What is known about that?"

"What little is known is unconfirmed. It is not unlike our own, having both Hunter and Constructor castes. The main difference would seem to be that they also have a Reproducer caste. However, this is all information from the First Ones."

"What are their vulnerabilities, physically?"

"Unknown, Zur; from their appearance we would postulate a similar physiology to the Wasps. But that is, at best, a guess."

"How fast do they dig their tunnels?" asked Horc.

"Unknown."

"How many Ants in a nest?" asked Zur.

"Unknown. It is believed to be in the thousands."

"Is the anthill we viewed a new nest, or a new outlet for an old colony?"

"Unknown, Commander."

There was a long moment of silence.

"If there are no further questions..." I began.

"There is one more bit of information which could be important to our planning, Commander."

"Proceed, Tzu."

"They possess some method of passing information among themselves. Whether this is done by direct contact, by telepathy, or even genetically is unknown. This characteristic of the Ants defied even the First Ones' attempts to explain."

The silence was longer this time as we digested the information.

"Horc," I said finally, "what does the presence of the Ants mean to the effectiveness of our Defense Network?"

"The Network was designed to detect and destroy surface creatures such as the Leapers. While it will still be effective against surface hunters, it will be totally ineffective against burrowing," he replied.

"Will your team be able to devise an effective defense?"

"There are two possibilities we can explore. One would be a device to detect sounds of burrowing. The other would be a machine to locate subterranean hollow points. It is doubtful, however, that they would be effective to a depth of two kilometers. With the equipment we have on hand, we couldn't guarantee coverage much deeper than a quarter kilometer, half a kilometer maximum."
