slim young girl who was moving down the aisle toward him.

Stupidly he had thought she was coming directly to him, and he experienced a shock of surprise when she passed him with no more than a casual glance. Even with her indifferent passing a thrill seemed to go through him; his blood began to sing in his veins, and through his mind there flashed again the lines which had stirred his boyhood fancy years ago:

"She the moonlight, starlight, firelight,
She the sunshine of her people,
Minnehaha, Laughing Water!"

CHAPTER II

IN THE TRAIN

Sahwah the Sunfish came tripping blithely down the Pullman aisle to rejoin the Winnebagos after a sojourn on the platform with the brakeman, whom she left exhausted with answering questions. When Sahwah traveled she traveled with all her might and there was nothing visible to the naked eye that she did not notice, inquire about, and store up for future reference. She observed down to the last nail wherein a Pullman differed from a day coach; she found out why the man ran along beside the train at the stations and hit the wheels with a hammer; why the cars had double windows; what the semaphore signals indicated; why the east-bound freight trains were so much more heavily loaded than the west-bound; she noticed that there were no large steamboats running on the Susquehanna, although it looked like a very large river; she counted the number of times they crossed the river on the run through the Alleghenies; she noticed the different varieties of trees that grew along the mountain sides; she scrutinized every passenger in the car and tried to guess who they were, what their business was and where they were going. Sahwah's mind was like a photographic plate; everything she looked at became imprinted there as upon a negative, accurate in every detail. Like the Elephant's Child, Sahwah was full of 'satiable curiosity, and her inquisitive trunk was always stretched out in a quivering search for information.

The brakeman, an amiable personage, was interested in her thirst for knowledge of railway affairs, and answered her innumerable questions in patient detail until his head began to buzz and he began to feel as though he were attached to a suction pump.

"Goodness gracious, child, what do you think I am, an encyclopedia?" he exploded at last, and sought refuge in the impenetrable regions at the forward end of the long train.

Sahwah, deprived of her source of information, turned to join her traveling companions, Gladys and Hinpoha and Migwan, up in the other end of the car. She stood for a moment at the water cooler, looking down the car at the people facing her and indulging in her favorite pastime of trying to read their faces. The car was crowded with all kinds of people, from the stately, judicial-looking man who sat in front of the Winnebagos to a negro couple on their honeymoon. There was a plentiful sprinkling of soldiers throughout the car and one or two sailors. Sahwah looked at them with eager interest and classified their different branches of service by the color of the cord on their hats. One Artillery, three Infantry, one Ambulance Corps and one Lieutenant of Aviation, she checked off, after a long and careful scrutiny of the last one, whose insignia puzzled her at first.

A porter brushed by her as she stood there with a glass of milk in his hand. Sahwah watched the progress of the milk idly, and the porter stopped beside the Lieutenant of Aviation with it. The lieutenant seemed to be asleep, for the porter had to shake him before he became aware of his existence. Just then Hinpoha caught Sahwah's eye and motioned her to come back to her seat, and Sahwah went tripping down the aisle to join her friends. She glanced casually at the young lieutenant as she passed him; he was staring fixedly at her and she dropped her eyes quickly. A little electric shock tingled through her as she met his eyes; he seemed to be about to speak to her. "Probably mistook me for someone else and thought he knew me," Sahwah thought to herself, and dismissed him from her mind.

"Where have you been all this while?" asked Hinpoha with a perspiring sigh, laboriously "knitting backward" across the length of the needle in vicious pursuit of a stitch that should have been eliminated in the process of decreasing for the heel turn.

"Pursuing knowledge," replied Sahwah merrily, settling herself in the seat beside Hinpoha, facing Migwan and Gladys.

The four girls were on their way to spend the summer vacation with their beloved Guardian, Nyoda, at her home in Oakwood, the little town in the hills of eastern Pennsylvania where she had lived since her marriage to Andrew Sheridan—"Sherry"—the summer before. Sherry was in France now with the Engineers, and Nyoda, lonesome in the huge old house to which she had fallen heir at the death of her last relative, old Uncle Jasper Carver, had invited the Winnebagos to come and spend the summer with her.

Vacation had begun inauspiciously for the Winnebagos. To their great disappointment Katherine wrote that she was not coming east after all; she was going to remain in Chicago with Miss Fairlee and help her with her settlement work there. They had rejoiced so at the first news of her coming and had so impatiently awaited the time of her arrival that the disappointment when it came was much harder to bear than if they had never looked forward to her coming. As Sahwah remarked, she had her appetite all fixed for Katherine, and nothing else would satisfy her. The news about Katherine had only been one of a series of disappointments.

Hinpoha had been called home the week before college closed officially, to attend the funeral of Dr. Hoffman, Aunt Phoebe's husband, whose strenuous work for his "boys" in the military camp during the past year had been too much for his already failing strength, and Aunt Phoebe, worn out with the strain of the last months, had announced her intention of closing the house and going to spend the summer with a girlhood friend on the Maine coast. Hinpoha had the choice of going with her or spending the summer with Aunt Grace, who had a fractured knee and was confined to an invalid's chair.

Migwan had come home from college with over-strained eyes and a weak chest and had been peremptorily forbidden to spend the vacation devouring volumes of Indian history as she had planned, and had a lost, aimless feeling in consequence.

Sahwah, thanks to the unceasing patriotic activities of Mrs. Osgood Harper during the previous winter, found herself unexpectedly in possession of a two months' vacation while her energetic employer recuperated from her season's labors in a famous sanatorium. As Sahwah had not expected a vacation and had made no plans, she found herself, as she expressed it, "all dressed up and no place to go."

For Gladys's father, head over heels in the manufacture of munitions, there would be no such glorious camping trip as there was the summer before, and Mrs. Evans refused to go away and leave him, so Gladys had the prospect of a summer in town, the first that she could recollect.

"I can't decide which I shall do," sighed Hinpoha plaintively to the other three, who had foregathered in the library of the Bradford home one afternoon at the beginning of the summer. "I know Aunt Phoebe would rather be alone with Miss Shirley, because her cottage is small, and it would be dreadfully dull for me besides; but Aunt Grace will be laid up all summer and she has a fright of a parrot that squawks from morning until night. Oh, dear, why can't things be as they were last year?"

Then had come Nyoda's letter:

DEAREST WINNEBAGOS:
Can't you take pity on me and relieve my loneliness? Here I am, in a
house that would make the ordinary hotel look like a bandbox, and since
Sherry has gone to France with the
