econd vertical velocity. Then we turned it on."

"And we rode it down, that little grid," said one of the remaining
Indians, grinning. "What a party! Manitou!"

Redfeather frowned at him and took up the narrative.

"It hurled the sand up from its center. As you said it would, the sand
swept air with it. It made a whirlwind, bringing more sand from outside
the grid into its field. It was a whirlwind with fifteen megakilowatts
of power to drive it. Some of the sand went twenty miles high. Then it
made a mushroom-head and the winds up yonder blew it to the west. It
came down a long way off, Mr. Bordman. We've made a new dune-area ten
miles downwind. And the little grid sank as the sand went away from
around it. We had to stop it three times, because it leaned. We had to
dig under parts of it to get it straight up again. But it went down into
the valley."

Bordman turned up the power to his heat-suit motors. He felt
uncomfortably warm.

"In six days," said Ralph, almost ceremonially, "it had uncovered half
the original grid we'd built. Then we were able to modify that to heave
sand and to let it tap the ionosphere. We were able to use a good many
times the power the little grid could apply to sand-lifting! In two days
more the landing grid was clear. The valley bottom was clean. We shifted
some hundreds of millions of tons of sand by landing grid, and now it is
possible to land the _Warlock_, and receive her supplies, and the
solar-power furnace is already turning out pigs for her loading. We
wanted you to see what we have done. The colony is no longer in danger,
and we shall have the grid completely finished for your inspection
before the ship is ready to return."

Bordman said uncomfortably:

"That's very good. It's excellent. I'll put it in my survey report."

"But," said Ralph, more ceremonially still, "we have the right to count
coup for the members of our tribe and clan. Now----"

Then there was confusion. Aletha's cousin was saying syllables that did
not mean anything at all. The other Indians joined in at intervals,
speaking gibberish. Aletha's eyes were shining and she looked incredibly
pleased and satisfied.

"But what ... what's this?" demanded Bordman when they stopped.

Aletha spoke proudly.

"Ralph just formally adopted you into the tribe, Mr. Bordman--and into
his clan and mine! He gave you a name I'll have to write down for you,
but it means, 'Man-who-believes-not-his-own-wisdom.' And now----"
