Gwen's quarrel with Netta was so complete that the two were no longer on speaking terms. Gwen was very apprehensive lest her former chum should carry out her old threat and betray the secret of the broken china, and in the first heat of her anger Netta had been inclined to do so; on further reflection, however, she decided that the consequences might be too compromising to herself, and that it would be safer to preserve silence. She had already scored by fetching Miss Trent into the schoolroom during Gwen's conversation with Dick, and the trouble which had ensued was almost enough to satisfy her. Really Netta had been rather tired of Gwen before this, and she was not sorry to seize upon an excuse for breaking their friendship. She now took up hotly with Annie Edwards, and the pair were for the moment inseparable.

"I believe it's as I thought," said Elspeth Frazer to Charlotte Perry; "Gwen Gascoyne's quite off with Netta. Now, if she can only get into a better set she may be a different girl. I want to find out what she's really like, so I'm going to be nice to her to-morrow when we go the geological excursion."

"Perhaps we have been rather horrid to her," returned Charlotte thoughtfully.
[180]

"It was mostly her own fault for putting on airs when she first came up, and then making such friends with Netta. She couldn't expect any of us to have anything to say to her after that."

"Probably she didn't know Netta."

"I dare say not; but it shows she's a bad judge of character. All the same I've got Gwen a little on my conscience, and I'm going to try what I can do. She may improve now."

Elspeth spoke the truth when she said that she had Gwen on her conscience. It had occurred to her several times lately that perhaps she had misunderstood her schoolfellow, and that she might have done more to help her. "Am I my brother's keeper?" rose uneasily to her mind. She had an uncomfortable feeling that in happier circumstances Gwen might have made a better impression on the Form, and that she and Hilda and Edith and Louise were partly responsible for her ill reception.

"I'm very sorry if we've been Pharisees!" she thought. "Of course one wanted to keep to one's own set, and not have anything to do with the tag-end of the Form—but—Well, I mean to give Gwen Gascoyne a chance now, anyhow."

The geological excursion was rather an event of the term. The Form had been learning geology with Miss Roberts, who promised to take the girls for an afternoon to Riggness, a place a few miles away on the coast, greatly noted for its fossils, where they could have a practical demonstration to supplement the information in their textbooks. On the Friday afternoon chosen for the ramble everybody started
[181]
armed with hammers of all varieties, from Miss Roberts's beautiful geological pick to stout tack hammers and even toffee hammers.

"One never knows—one might find an ichthyosaurus embedded in the cliffs!" declared Charlotte Perry, brandishing a wooden mallet and an iron wedge, as if she were prepared to clear away tons of rock in the pursuit of her researches.

"Don't I wish we could!" said Miss Roberts. "But I'm afraid a few ammonites and belemnites will have to content us; those are quite difficult enough to get out intact. We shall do very well if we can only bring back some really perfect specimens for the school museum."

Riggness was on the other side of Stedburgh from Skelwick, and Gwen had never been there before, so the excursion was new to her. It was great fun going with the whole Form; the girls had come well prepared to enjoy themselves, and Miss Roberts also was in a jolly frame of mind, and had even brought with her a box of chocolates, which she handed round impartially till the contents vanished. Three compartments seemed to overflow with Rodenhurst hats. Gwen had just been following Millicent Cooper and Minna Jennings when Elspeth Frazer gripped her by the arm.

"Come in here with us, Gwen," she said, and Gwen, too much astonished for words, complied. Why she should be invited into a carriage with Hilda Browne, Charlotte Perry, Iris Watson, Louise Mawson, and Edith Arnold, the most elect set in the Form, was beyond her comprehension, but it was a very pleasant
[182]
circumstance all the same. To be sure, they did not take much notice of her, but they were not disagreeable, and Elspeth spoke to her more than once in quite a friendly fashion. It was so utterly different from their former attitude towards her that Gwen almost believed she was dreaming. Perhaps it was only because they were on a holiday this afternoon, she thought, and to-morrow they would be as usual again. Well, at any rate, she would take advantage of to-day, and make the most of her opportunities, so she chatted a little with Elspeth, and sat ruminating over this amazing change of front on the part of those girls whom Netta, in mockery, had nicknamed "The Saints". Riggness was reached in twenty minutes, the train stopped at the small wayside station, and the Rodenhurst party got out in a hurry. They were to descend to the beach, and walk along the shore to Linkthwaite Bay, a distance of about three miles, geologizing as they went. A steep zigzag path led down the side of the cliff to the sands, and when once her flock was all collected at the bottom, Miss Roberts improved the occasion by giving a short lecture on the formation of the rocks which formed the headland, then, leading the way, she showed them how to hunt about for the ammonites embedded in the face of the cliffs, or the long belemnites that could be seen in flat terraces of rocks at the water's edge.

"Miss Roberts is right—they're uncommonly difficult to get out whole," said Elspeth, tapping gingerly round a particularly fine specimen; "just when you think you've done it, they go smash."

"It's most aggravating," agreed Gwen, whose heavy
[183]
hammer, borrowed from Winnie's hen-yard, had been rather too forcible in its effects. "I'd almost got the loveliest, biggest belemnite, and it broke into three pieces like a slate pencil."

"I like my toffee hammer best," said Charlotte, tenderly fingering one or two good specimens which she had managed to secure. "I mean to save up and buy a real geological one like Miss Roberts's."

Tapping the rocks was a fascinating occupation, and a fairly profitable one, for this part of the coast was rich in fossils. By the time the girls had walked a mile along the shore they had all been able to procure some souvenirs, though as yet nothing of very special importance. Miss Roberts looked about with a practised eye, and the pick end of her hammer would withdraw a specimen neatly, where clumsier blows worked havoc.

"We'll hurry on a little farther now," she said. "Those cliffs in the middle of the bay are a particularly good hunting ground, and if there's anything interesting to be found, we ought to find it there."

At the place in question the rocks were intersected by a narrow gorge, where a small stream trickled its way from the moorlands above. The shelving platforms of the cliff were here comparatively easy to climb, and the action of water and weather combined had carried down a mass of stones and debris that would be worth investigation. Miss Roberts was as active and enthusiastic as any of the girls; she jumped lightly from stone to stone, tapping likely spots with her hammer, and finally, seeing something protruding from a rock above, began to scale the face of the cliff.

"I believe I've got something here at last!" she called.

"Oh! what is it?" cried the eager girls.

"I can't tell yet till I've cleared it a little."

"Oh! Is it an ichthyosaurus, do you think?" cried Charlotte Perry.

"I'm going to send down a shower of stones—stand out of the way!" commanded Miss Roberts, and balancing herself nimbly on a narrow led............
