y name is Wilson. I manned the remote control panel for the Duplicator Construction Company.

As you know, we directed a battery of building machines which erected mass housing projects. I directed only the destination of our machines. Once I sent them to a site, they completed their work automatically with the materials installed at our supply depot.

A single machine could prepare a site and erect a complete house in one day. With an army of 5,000 machines, our firm had succeeded in building as many houses as there was room for, and we had started on the demolition of our original buildings for replacement with the modern economy-size model. This made room for three families where one had lived before. We started this replacement program the week before the Calamity.

The first hint of trouble was a call from a checker to the front office. I happened to be there when he appeared on the vid-screen and said that one of our machines had built a Chinese pagoda. He seemed to think it was funny.

Then we began to receive other reports. Our machines were building grape arbors, covered bridges, cloisters, music halls, green houses, dancing pavilions and hunting lodges.

One machine was not building at all, but had gone on a rampage, clearing ground where we had just completed one thousand of the new economy-size dwelling units.

The machine was dynamited by our emergency squad.
