I followed that road for seventy-five miles, and as I went the signs kept getting newer and newer until I finally came to a truck loaded with pipe, hardware, and ornamental ironwork. Leading the truck was one of those iron mole things.

I watched the automatic gear hoist one of the old pipe and white and black enamel roadsigns up by its roots, and place it on a truck full of discards. I watched the mole drive a corkscrew blade into the ground with a roaring of engine and bucking of the truck. It paused, pulled upward to bring out the screw and its load of dirt, stones and gravel. The crew placed one of the new signs in the cradle and I watched the machine set the sign upright, pour the concrete, tamp down the earth, and then move along down the road.

There was little point in asking questions of the crew, so I just took off and drove to Columbus as hard as I could make it.

Shined, cleaned, polished, and very conservatively dressed, I presented myself to the State Commissioner of Roads and Highways.

On the other hand, mere curiosity on the part of a citizen, well oiled with compliments, would get me at the very least a polite answer.

The Commissioner's fifth-under-secretary bucked me down the hall; another office bucked me upstairs. A third buck-around brought me to the Department of Highways Marking and Road Maps.

I still played it straight. I told him I was a citizen of New York, interested in the new road signs, Ohio was to be commended, et cetera.

"I'm glad you feel that way," he said beaming.

"I presume these signs cost quite a bit more than the stark, black and white enamel jobs?"

"On the contrary," he said with pride. "They might, but mass-production methods brought the cost down. You see, the enamel jobs, while we buy several thousand of the plates for any highway, must be set up, stamped out, enamelled, and so on. The new signs are all made in one
