Steve spoke in such a tragic tone that Rose took another peep and did sympathize with Dandy; for Mac's elegance was quite gone. His tie was under one ear, his posy hung upside down, his gloves were rolled into a ball, which he absently squeezed and pounded as he talked, and his hair looked as if a whirlwind had passed over it; for his ten fingers set it on end now and then, as they had a habit of doing when he studied or talked earnestly. But he looked so happy and wide awake, in spite of his dishevelment, that Rose gave an approving nod, and said behind her fan,-- "It _is_ a trying spectacle, Steve: yet, on the whole, I think his own odd ways suit him best; and I fancy we shall yet be proud of him, for he knows more than all the rest of us put together. 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. When this pleasing fact dawned upon Rose, her feelings may be imagined. She was both angry and amused: it was so like Mac to go mooning off and leave her to her fate. Not a hard one, however; for, though Steve was gone with Kitty before her flight was discovered, Mrs. Bliss was only too glad to take the deserted damsel under her wing, and bear her safely home. Rose was warming her feet, and sipping the chocolate which Phebe always had ready for her, as she never ate suppers; when a hurried tap came at the long window whence the light streamed, and Mac's voice was heard softly asking to be let in "just for one minute." Curious to know what had befallen him, Rose bade Phebe obey his call; and the delinquent cavalier appeared, breathless, anxious, and more dilapidated than ever: for he had forgotten his overcoat; his tie was at the back of his neck now; and his hair as rampantly erect as if all the winds of heaven had been blowing freely through it, as they had; for he had been tearing to and fro the last half-hour trying to undo the dreadful deed he had so innocently committed.
