With their skates strapped together and slung over their shoulders, their collars turned up around their ears, and their hands plunged deep into pockets and muffs, they turned northward along the bank of the creek for a short distance, and then struck off across the level, open ground till they came into one of the streets of the little town, which they followed until they reached the main business street. There they parted, Ned and Marjorie turning to the west, while Howard and Allie kept straight on towards the north, and finally stopped at a small brick house, a low, one-story affair, yet much more elaborate than the average dwelling of the town, where the architecture was largely of the log-house species, though often covered with a layer of boards to disguise the primitive nature of the materials.

The front door opened directly into the little parlor, and into this cosy room Howard and Allie plunged, laughing and breathless after their quick walk in the cold. A bright-faced little woman sat sewing by the front window, holding up her work to catch the last fading light, and a rosy boy, two years old, was tumbling about on the carpet, rolling over and over the great dog, who was dozing as peacefully as if such demonstrations were quite to his liking.

"Hullo, mammy! Hullo, Vic! Dinner ready?" exclaimed Howard, casting his skates into the nearest chair, and moving up to the stove to warm his chilled fingers.

"How was the skating?" asked his mother, looking up from her work to smile at Allie, as she pulled off her coat and hat, and then caught up the child from the floor.

"Fine; but we're 'most starved—at least, I am," returned Howard, as he wriggled himself out of his coat and handed it to Allie, who received it quite as a matter of course, and went away to hang it in its usual place.

"Well, dinner is all ready, and papa will be here in a minute; so you can go and tell Janey to take it up. Do you know," she added, with a laugh which took all the sting from the reproof; "I think it is time my boy learned to take his sister's coat for her, instead of expecting her to wait on him."

"All right," answered Howard, by no means abashed by the rebuke. "Here, sis, if you'll just bring back your coat and put it on again, I'll see what can be done about it." And he bent over to stroke his mother's hair with a boyish affection which filled her heart with gratitude for having such a son, even while it sent her off to her toilet table to repair the damages which his fingers had wrought. Then he marched out to the kitchen to tease Janey, until she threatened to pour the soup over his favorite pudding, unless he left her to take up the dinner in peace.

Mr. Burnam, Howard's father, was a successful civil engineer, who, in the line of his professional life, had been ordered up and down the West according to the demands of the great railroad corporation by whom he was employed. The life of a locating engineer is much like that of the soldier, in its need for strict obedience to orders, and for eighteen years Mr. Burnam had been stationed, now here, now there,—on the rolling prairies of Iowa, in the Dakota bad lands, in the alkali deserts of Wyoming, and among the cañons and passes of the Colorado Rockies. Six months before this time he had been ordered to western Montana, to lay out a possible railway across the mountains, which should give the Pacific-coast cities a more direct connection with their eastern neighbors. The survey for this line would occupy him for a year or more, and in order to have his family near him during this time, he had made his headquarters in the little mining camp, which the first prospectors along the cañon, some four years before, had christened "Blue Creek," from the clear, bright waters of the mountain stream. Here he established his family in the most comfortable house that the town afforded, and here he had his office, which served as headquarters for his corps of men, whenever they came in town for a few days. By virtue of his position as chief of the party, Mr. Burnam often spent weeks at a time at home, working up his estimates and maps, and only driving out to camp now and then, for a day or two, to see that all was well in his absence. Then, just as his family were settling down to the full enjoyment of his society, he would be sent for, to oversee some difficult bit of work, and Mrs. Burnam and Allie would be left to the protection of Howard, and of Ben, the great Siberian bloodhound, who was as gentle as a kitten until molested, when all his old savage instincts sprang into life.

One of the early graduates from Cornell, Mr. Burnam had gone West when a mere boy, fresh from college; and now, at forty, he had made himself a brilliant reputation in his profession. The chief, as they called him, was adored by all his men, who knew, from long experience, that however great the danger and hardship might be, he was always ready to share it with them, and that he made it a part of his creed never to ask a subordinate to take a risk which he himself would shun. Quick-tempered and outspoken in the presence of any suspicion of shirking or deceit, he was yet a just, honorable man in dealing with his "boys," who loved and respected him accordingly. At home, he was a different man; for he threw aside his professional dignity, to tease his wife, or romp with his children, lavishing upon them all the love of which his great, generous nature was capable.

For the sake of her husband, Mrs. Burnam had willingly cut herself adrift from her family and friends in New York, and for sixteen years she had patiently followed him here and there through the West; now living in camp for a summer, now boarding at tiny country hotels, in order to be within driving distance of his party; now left for months at a time in the busy solitude of a great city hotel, while Mr. Burnam was far away in unexplored forests, and often, as now, settled near him for a few months of housekeeping which should give her children at least a slight knowledge of home life and its charms.
