I didn’t show either her or Bill the pen that was a fishing-rod, for I was scared of that. Flourish it around a bit and there was no telling what would happen.

Bill was interested and excited, of course. This was trading, which was right down his alley.

I cautioned both of them not to say a word about it. Bill wouldn’t, for he was hell on secrets and special codes. But bright and early in the morning, Helen would probably swear Marge to secrecy, then tell her all about it and there wasn’t a thing that I could do or say to stop her.

Bill wanted to put the pink-lensed spectacles on right away, to see how they were different from any other kind. I wouldn’t let him. I wanted to put those specs on myself, but I was afraid to, if you want to know the truth.

When Helen went out to the kitchen to get dinner, Bill and I held a strategy session. For a ten-year-old, Bill had a lot of good ideas. We agreed that we ought to get some system into the trading, because, as Bill pointed out, the idea of swopping sight unseen was a risky sort of business. A fellow ought to have some say in what he was getting in return.

But to arrive at an understanding with whoever we were trading with meant that we’d have to set up some sort of communication system. And how do you communicate with someone you don’t know the first thing about, except that perhaps it has three eyes?

Then Bill hit upon what seemed a right idea. What we needed, he said, was a catalogue. If you were going to trade with someone, the logical first step would be to let them know what you had to trade.

To be worth anything in such a circumstance, it would have to be an illustrated catalogue. And even then it might be worthless, for how could we be sure that the Trader on the other side of the desk would know what a picture was? Maybe he’d never seen a picture before. Maybe he saw differently—not so much physically, although that was possible, too, but from a different viewpoint and with totally alien concepts.

But it was the only thing we had to go on, so we settled down to work up a catalogue. Bill thought we should draw one, but neither of us was any good at drawing. I suggested illustrations from magazines. But that wasn’t too hot an idea, either, for pictures of items in the magazine ads are usually all prettied up, designed to catch the eye.

Then Bill had a top-notch idea. “You know that kid dictionary Aunt Ethel gave me? Why don’t we send that to them? It’s got a lot of pictures and not much reading in it, and that’s important. The reading might confuse them.”
