Matilda Cookson had remained very true to her allegiance, and would at this time have proved an interesting study to any psychologist whose path she had chanced to cross. Almost at a glance he could have divided all the opinions she uttered into two classes—those that were her own, and those that were Mona's. The former were expressed with timid deference; the latter were flung in the face of her acquaintances, with a dogmatic air of finality that was none the less irritating because the opinions themselves were occasionally novel and striking. Matilda glowed with pride when she repeated a bold and original remark; she stammered and blushed when one of her own poor fledgelings stole into the light. It was on the former that a rapidly developing reputation for "cleverness" was insecurely based; it was the latter that delighted Mona's heart, and made her intercourse with the girl a source of never-ceasing interest. It is so easy to heap fuel on another mind; but to apply the first spark, to watch it flicker, and glow, and catch hold—that is one of the things that is worth living for.

To one of Mona's protégées Rachel never even referred, and that was the girl who had fainted at the soirée. Mona had taken an interest in her patient, had prescribed a course of arsenic and green vegetables; and the improvement in the girl's appearance had seemed almost miraculous.

"She usedna tae be able tae gang up the stair wi'oot sittin' doon tae get her breath," said her grandmother to Miss Simpson one day; "an' noo, my word! she's awa' like a cat up a tree."

Rachel carefully refrained from repeating this remark to Mona. She was afraid that so surprising a result might encourage her cousin to persevere in a work which Rachel fondly hoped had been relinquished for ever. The good soul had been much depressed on chancing to see the prescription which Mona had written for the girl. Why, it was a real prescription—like one of Dr Burns'! When a woman had got the length of writing that, what was the use of telling her she would never make a doctor? What more, when you came to think of it, did doctors do? There was nothing for it but to encourage Mr Brown, and Rachel forthwith determined to invite him and his sisters to tea.

The study of the Musci, Algæ, and Fungi had not proved a striking success hitherto. There had been one delightful ramble among the rocks and pools, but since then the pursuit had somewhat flagged. Several excursions had been arranged, but all had fallen through. On one occasion Miss Brown had been confined to the house; on another she had been obliged to visit an aunt who was ill; and on a third the weather had been unpropitious.

"My dear," said Rachel one day, after the formation of the bold resolution above recorded, "if you are going in to Kirkstoun, you might stop at Donald's on the Shore, and order some cookies and shortbread. To-morrow's the day the cart comes round, and I'm expecting Mr Brown and his sisters to tea."

Mona nearly dropped the box of tape she was holding.

"Dear cousin," she said, "the sisters have never called on you, have they?"

"No," replied Rachel frankly, "but one must make a beginning. They offered us tea the day we were there."

"I promised Mrs Ewing that I would play the organ for the choir practice to-morrow evening."
