“Jean, that was it! Why, do you know I never saw one before, and to think I did not find them last week! Now find me a new water-bird, and the S. P.’s may study birds with me forever!”

At that the S. P.’s began to look about in earnest. “We have black terns that nest here,” said Leigh. “Father knows them.”

As if in response to their eager desire, that of pleasing their new friend, two birds flew out of the reeds and settled upon the narrow beach. “Oh,” gasped Miss Haynes, forgetting girls and everything as she stood with her glass at her eyes. The girls stood stock still, not caring to look for themselves, for these were birds that circled about the lake all summer, birds in every variety of plumage, adult or immature.

But one of these two terns was the adult male bird, with its black head, neck, breast and underbody. The other bird was still in winter plumage, or was immature. “I don’t know whether that bird ought to be black at this time or not,” breathed Miss Haynes to herself, “but it is. Put down in your notes, Nan, that the S. P.’s have shown their teacher two new birds this day! Now let us have lunch.”

Enough material was found that would burn, especially as Jean’s kettle contained some kindling and paper below her sandwiches. Let the Indians make fires without matches. The S. P.’s would do it in the quickest way possible. There was not much danger that they would set fire to anything so damp as the surrounding woods, but they were careful, for the wind had dried the leaves in some places. It was a mild breeze now and the sun was warm. They screened their fire from the wind by dragging a log around and putting some branches up against it, or behind it in the sand. “We’ve had a fire here before,” the girls said, by way of explaining how they could so easily find two posts, so to speak, that supported a third long piece from which Jean’s kettle could hang. It was a little insecure, but Jean watched it, ready to catch the kettle’s looping handle upon a long stick which she held.

“The boys usually drive down the supports for us,” said Bess, “but we have to learn to be independent now. We’ll take you to a beach party on Lake Michigan some time, Miss Haynes, if you will go. We’ll get some wild place where the gulls are likely to be, if you like.”

“I shall like very much, Bess, and I will go with pleasure.”

The fire was allowed to die down as soon as the cocoa had come to the proper stage. Water from the spring was poured upon it, for they wanted to leave as soon as the lunch was eaten. Along the old log they sat to eat their sandwiches and fruit and drink their warming cocoa, though the sun shone down upon their backs and kept them from being chilled.

Nan drew from her pocket the notes which she had scribbled on the way. “Tree sparrow, fox sparrow, junco, song sparrow, robin, bronzed grackle, white-breasted nuthatch, tufted titmouse, meadow lark, red-winged blackbird, chickadee, turtle dove,—I guess that’s all.” But on the way back they added more, though only recording those that the S. P.’s had actually identified, or had thoroughly noted themselves.

Where two sloppy roads met, on the way from the lake, several of the Black Wizards came along, just ahead of the girls, to enter the main road from the one at an angle to that taken by the S. P.’s. “I wonder where the boys have been,” said Jean to Nan.
