On the way, it struck me that at the foot of the trees some tin sheets completely eaten with rust had been set up which I had not seen there the day before.

I asked why they did not move them out of the way; somebody might be injured by them.

In reply I was given a most resentful look.

"I would have you know," said Zemoeki, "that they are the Bigrusts which are displayed on solemn occasions." From this I understood only that I had made a blunder again, so, much more softly and with respect, I inquired after the nature of the Bigrusts, at which it came to light that that too, was an aneba.

"I'm no boaster," Zeremble said, "but I can tell you that my sheet of iron became holed with rust no less than eighty years ago."

And he looked around proudly.

But Zemoeki remarked that on his sheet of iron the rust was already two inches thick.

Now I was very curious and, to avoid any blunder, on the basis of my previous experiences, I flatteringly praised Zemoeki's Bigrust though I had no idea what that signified.

This method did indeed open their hearts and while we proceeded they explained every rusty sheet of iron.
