"That betokens great heat, I suppose," I said, pointing out the appearance I observed to my companion.

"I suppose so. That bluish mist probably increases in hot and sultry weather," she said. "But it is always to be seen more or less in this country, and is, I believe, peculiar to some of the German hill and forest districts. I don't know what it comes from—whether it has to do with the immense number of pines in the forests, perhaps. Some one, I think, once told me that it indicates the presence of a great deal of electricity in the air, but I am far too ignorant to know if that is true or not."

"And I am far too ignorant to know what the effect would be if it were so," I said. "It is a very healthy country, is it not?"

"For strangers it certainly is. Doctors send their patients here from all parts of Germany. But the inhabitants themselves do not seem strong or healthy. One sees a good many deformed people, and they all look pale and thin—much less robust than the people of the Black Forest. But that may come from their poverty—the peasants of the Black Forest are proverbially well off."

A distant, very distant, peal of thunder was heard at this moment.

"I hope the weather is not going to break up just yet," I said. "Are there often bad thunderstorms here?"

"Yes; I think we do have a good many in this part of the world," she replied. "But I do not think there are any signs of one at present."

And then, still a little sleepy and tired from our unusual exertions of the last three days, we all three, Frau von Walden, Nora, and myself, sat very still for some time, though the sound of Reggie's voice persistently endeavouring to make the driver understand his inquiries, showed that he was as lively as ever.

He turned round after a while in triumph.

"Mamma, Frau von Walden," he exclaimed, "we are close to that place where they make the cups and saucers. Herr von Walden said we weren't to forget to go there—and you all would have forgotten, you see, if it hadn't been for me," he added complacently.
