Then as he crossed the veranda Agatha came up from the beach and gave him a smile.

"You are out early," Thirlwell remarked.

"I like the morning freshness and have been on the lake."

"It looks as if you had hurt yourself," said Thirlwell, noting a small wet handkerchief twisted round her hand.

Agatha laughed. "Not seriously; I blistered my fingers trying to paddle.

I have been practising since I came, but it is difficult to keep the canoe straight when you are alone."

"That's so," Thirlwell agreed. "The back-feathering stroke is hard to learn."

"For all that, I mean to learn it before I go."

"Perhaps I could teach it you. How long have you got?"

"A fortnight," she said, moving on, and when she left him Thirlwell went to the mail-box and dropped in his letter.

Afterwards he felt annoyed that he had done so, and wondered whether he had weakly given way to a romantic impulse, but next morning he went down to the beach and found the girl launching a canoe. Making her sit near the middle, he knelt in the stern and drove the canoe across the shining water with vigorous strokes. Agatha wore a white jersey and had left her hat, and he noted the color the cool wind brought to her face and how the light sparkled on her hair.

By and by they skirted a rocky island where resinous smells drifted across the water and the reflections of tall pines wavered round the canoe, until he ran the craft on a shingle point and they changed places. Agatha took the single-bladed paddle and although her hands were sore made some progress while he instructed her. After a time she stopped and let the canoe drift in the hot sunshine.

"I think you'd soon make a good _voyageur_," Thirlwell remarked. "For one thing, you're determined; I saw you wince once or twice and imagine the paddle-haft hurt."

"I must learn to use the pole yet, and mean to try it in the river by and by. You must pole, I think, when you go up a fast stream?"

"That is so, when you can't use the tracking line. But I don't see why you are anxious to learn."

"I have an object," Agatha answered with a smile.

"Then why don't you practise canoeing at Toronto?"

"The trouble is that I haven't time. You see, I teach all day."

"But you have holidays and the evenings."

"My evenings are occupied by study."

"I don't know if it's wise to over-work yourself for the advantage of your pupils," Thirlwell remarked. "At one time, I was very keen about my profession, but soon found it a mistake to tire my brain for my employer's benefit. But what do you study?"

"Science; chemistry and geology, but not in order to teach the girls."

"Well, I suppose knowledge is worth getting for its own sake. Anyhow, I thought so, but you learn when you undertake rude mining that the main thing is to be able to make a practical use of what you know. In fact, that's often better than knowing much."

"Perhaps so," Agatha agreed. "Some day I hope to make a good use of what I have learned."

"About canoeing, or geology?"

"About both," said Agatha. "Now, however, I think we'll make for the landing. Breakfast will be ready soon."

Thirlwell saw no more of her during the day, but she came down to the beach in the evening and he gave her another lesson. As they paddled home he thought she looked tired, and asked: "Where have you been since morning?"

Agatha indicated a ridge of high ground with a few pines on its summit that rose indistinctly at some distance across the shadowy forest.

"I took my lunch with me and went up there."

"But it must be a two or three hours' walk. Is there a trail?"

"A loggers' trail. It's partly grown up and broke off altogether when I got near the rocks. After that I had a rough scramble, but I like the woods and try to walk as much as possible in my holidays."

"Well, no doubt, walking is good for one. But don't the girls in Toronto prefer the street cars?"

"I don't go long walks for health's sake," Agatha answered with a smile.

"But I think some people I know are waiting. Can you paddle faster?"

The canoe's bows lifted out of a wisp of foam as Thirlwell swung the paddle, and in a few minutes he helped the girl to land. After this, their acquaintance ripened fast and Agatha went fishing with him on the lake and, by disused logging trails, long distances into the shadowy bush. Thirlwell imagined she knew this excited some remark, but he saw there was an imperious vein in the girl, who did what she thought fit, without heeding conventions. Besides, no touch of sentiment marked their friendship; she accepted him as a comrade who could teach her something about lake and forest, and he was satisfied with this.

Yet he was puzzled. It was strange that an attractive girl should wish to learn something of the bush-man's skill, but she obviously meant to do so. Although it often cost her an effort to follow him, she would not let him turn back when they came to an angry rapid or a belt of tangled woods. She certainly had charm besides having pluck, because when she did not go fishing young women as well as young men gathered round her on the shady lawn. It was hard to imagine why a girl like this should practise walking long distances and combine the study of canoeing with geology.

The fortnight slipped by and on the last evening Thirlwell took Agatha out upon the lake. They were later than usual and as they stole across the gla.s.sy water the pines on a western headland cut black and sharp against an orange glow. To the east a faint track of silver ran back into the blue distance under the moon. It was very quiet except for the splash of the paddle and ripple at the bows, but somewhere in the shadows a loon was calling. By and by the lights of the hotel faded and they were alone in the dusk.

Thirlwell put down the paddle and lighted a cigarette. He had drawn nearer the girl in the last week; a curious feeling of confidence and liking united them, but he was not her lover and knew that if he drifted into philandering she would be repelled. Perhaps this was unusual, but she was different from other girls. Thirlwell could not tell how she differed, but he was satisfied that she did and let the matter go.

"You start for the mine to-morrow, don't you?" she asked presently.

"Yes," he said; "it's my last evening on the lake. There's something melancholy about the end of a holiday, but I don't think I have felt it as much before."

Agatha gave him a calm glance and saw he had not meant her to read a sentimental meaning in his admission. It was unconscious flattery and she was pleased.

"I can understand. One values the days of liberty when they are gone!

But do you feel daunted by the thought of the work and hardship that waits you in the North?"

"Not in a way. Now and then you shrink from the arctic winter, but in summer, in spite of the mosquitoes, the bush gets hold of you. Sometimes you hate the solitude; but when you leave it you long to return."

"Ah," said Agatha, "I have not seen the wilderness, but next summer I hope to make an exploring trip."

"But where?"

"To the Shadow River and on into the Territories," she answered quietly.

Thirlwell looked hard at her, and she smiled. "Yes; if things go well with me, I mean to look for the silver ore."

"Now I begin to understand! This is why you wanted to learn to manage a canoe and train yourself to walking through the bush. But it's a ridiculous undertaking. Your father, who found it, could not locate the ore again."

"I may be luckier. Luck counts for something when you go prospecting, doesn't it?"

"Success in prospecting is often due to luck," Thirlwell admitted. "But it's a very rough country where no food can be got. You will need canoes, tools, and tents, and two or three good packers to carry the outfit across the divides. This would be expensive. Then I doubt if you are strong enough to bear the strain; I imagine very few women could do so without breaking down."

"You have seen how I have tried to harden myself, but I have made other preparations. It's some time since I resolved to go, and every month I put by a little money. By next summer I ought to have enough."
