Hear that now," and Rose paused, that they might listen to the following burst of eloquence from Mac's lips:—
"You know Frenzel has shown that the globular forms of silicate of bismuth at Schneeburg and Johanngeorgenstadt are not isometric, but monoclinic in crystalline form; and consequently he separates them from the old eulytite, and gives them the new name Agricolite."
"Isn't it awful? Let us get out of this before there's another avalanche, or we shall be globular silicates and isometric crystals in spite of ourselves," whispered Steve with a panic-stricken air; and they fled from the hail-storm of hard words that rattled about their ears, leaving Mac to enjoy himself in his own way.
But when Rose was ready to go home, and looked about for her escort, he was nowhere to be seen; for the professor had departed, and Mac with him, so absorbed in some new topic that he entirely forgot his cousin, and went placidly home, still pondering on the charms of geology.
