"Come and have a taste of star-light!" he said.

The girls rose at once, and were ready in a minute.

The chief was walking between the two ladies, and Ian was a few steps in front, his head bent as in thought. Suddenly, Mercy saw him spread out his arms toward the starry vault, with his face to its serrated edge of mountain-tops. The feeling, almost the sense of another presence awoke in her, and as quickly vanished. The thought, IS HE A PANTHEIST? took its place. Had she not surprised him in an act of worship? In that wide outspreading of the lifted arms, was he not worshipping the whole, the Pan? Sky and stars and mountains and sea were his God! She walked aghast, forgetful of a hundred things she had heard him say that might have settled the point. She had, during the last day or two, been reading an article in which PANTHEISM was once and again referred to with more horror than definiteness. Recovering herself a little, she ventured approach to the subject.

"Macruadh," she said, "Mr. Ian and you often say things about NATURE that I cannot understand: I wish you would tell me what you mean by it."

"By what?" asked Alister.

"By NATURE" answered Mercy. "I heard Mr. Ian say, for instance, the other night, that he did not like Nature to take liberties with him; you said she might take what liberties with you she pleased; and then you went on talking so that I could not understand a word either of you said!"

While she spoke, Ian had turned and rejoined them, and they were now walking in a line, Mercy between the two men, and Christina on Ian's right. The brothers looked at each other: it would be hard to make her understand just that example! Something more rudimentary must prepare the way! Silence fell for a moment, and then Ian said—

"We mean by nature every visitation of the outside world through our senses."

"More plainly, please Mr. Ian! You cannot imagine how stupid I feel when you are talking your thinks, as once I heard a child call them."

"I mean by nature, then, all that you see and hear and smell and taste and feel of the things round about you."
