One rapidly advancing trouble was on his mind. He had not spoken to Ynys of the passing of her holiday, but he himself could almost hear its seconds ticking away. Soon two days only remained; the morrow, when he would see her on Delyn again, would be the eve of her departure. She had told him that she had taken a return ticket; already he seemed to hear the whistle of the train by which it was available. She could take that train either at Llanyglo or at Porth Neigr.
On the morning of her last whole day he ascended the Glyn and found, as usual, his trout cooked for him and keeping hot between two plates. He ate it abstractedly. Again Minetta had remarked pointedly on his lack of fishing-luck, but it was not that that was troubling him. He was wondering, not for the first time, what explanation Ynys gave herself of his untouched rods and buckled fly-book, and whether she too thought it unusual that he should come so far merely to lie by the stream with her hour after hour, or else, with a "Shall we go up there?" to ascend the stream, skirt the wood, gain the open mountain-side, and toil for half an hour to the summit. He had substituted no other pretence for his first pretence of fishing. What did she think of it? Or did she not think of it at all?
Again that morning, when she had scoured the plates and set them in a little rocky basin by the quivering moss, he proposed the mountain climb. In half an hour they were at the top. It was a plateau of volcanic rock, with scrubs of hazel, and bents and reeds and harebells ceaselessly stroked by the wind. Behind them, as they sat down under a rock, only Mynedd Mawr rose higher than they; below them Llyn Delyn lay like a bit of grey looking-glass set in its little mile-long cleft. They had raised other bits of looking-glass, too, in other far-off clefts. About them the mountains rolled as if invisible giants were being tossed in the visible blankets of the land. On the left only, far from Llanyglo, a scratch of silver showed that the sea was there.
"So you're off to-morrow," he said, when they had lain long. He did not hide from himself the ache the words caused him.
"My tick-ket say to-morrow," she answered, without emotion.
He muttered something foolish about an extension.—"But I suppose they wouldn't keep your place open," he answered himself hopelessly.
Her next words caused him a marvellous pang of lightness and hope.
"I think-k I not go back," she said, the seaweed eyes looking at that far-off silver scratch that was the sea.
Why did that pang at which he had winced instantly become another pang, at which he winced no less? What was it that the eyes of his spirit saw, far, far, farther off than her seaweed ones saw the sea? Her decision to stay, if she really meant that she would stay, should have meant the continuance of his happiness; what, then, should change it into something like an unhappiness and a fear?
He did not know. He was only an ordinary young man. He only knew that over that moment, which should have been one of a care removed, a faint shadow of an irremovable care already impinged.
