"Are we having difficulties with General Food-Concentrates, the Travelers Capsule Combine and the other ten thousand concerns in this line, Mr. Jones?" the bald Commissioner asked quietly.

You can't say I didn't try. I shut up and watched Lood fuss with the dust on the table.

It started moving as if it were bubbling and Lood stood back.

Slowly, the dust on the table formed itself into a brick, a long eight by six by three inch brick. Lood smiled happily.

"And here, Your Honors," I said triumphantly, "here is automatic housing."

"One brick does not make a house, Mr. Jones."

"If Your Honors will just watch...."

The brick slowly elongated and split into two perfect bricks, lying on the table end to end.

"Mass colony action of bacteria," said Lood wisely. "Oh, yus."

The two bricks each split into two further bricks. These divided and multiplied themselves while we watched, out to the end of the table.
