Madame Antoinette Bretton went for the third time to the door of her tiny cottage and, shading her eyes, looked anxiously up the side of the ice-capped mountain that flanked the garden. There was still no one in sight, and with a shake of her head she returned to the coarse grey socks she was knitting.

It was late afternoon, and through the stillness she could hear the roar of the river, the tinkle of herd-bells, and the faint sound of chimes from the far-away village chapel. How quiet the house seemed without Marie and Pierre! The boy and girl had climbed to the hillside pasture to drive the goats down for milking and Hector, the great St. Bernard dog that had been the children's companion ever since they were born, had gone with them, for Hector was an expert at rounding up a herd. Although he was not a young dog he had the zeal of a puppy; with this he combined the wisdom of a sage, and it was for the latter reason that Madame Bretton never worried about her children when Hector was with them. For to Madame Bretton the boy and the girl were still children. Neither Hector, Marie, nor Pierre had dreamed of being really grown up until the Great War had come and Monsieur Bretton, together with Uncle Jacques, had been called to the colors of France.

Throughout the valley were other boys and girls whose fathers, brothers, and uncles had left their homes behind—boys and girls who were not as old as Marie or Pierre, but who nevertheless were courageously trying to do the work of their elders. Marie was now nearly fifteen, and Pierre was sixteen; but when suddenly called upon to take their father's place, they felt much older. Yesterday they had been children with little to do but play; to-day work was ahead of them, much hard work, which seemed to have aged them in a single night and turned them from boy and girl into responsible grown up persons.

What a different village Bellerivre was with so many of its men away!

Yet how bravely its peasants had responded to the call, and how dauntlessly those left behind had risen to meet the new conditions of living!

"We who remain at home must keep things running in the customary grooves, so that our soldiers may find the town unchanged when they return," had been the cry.

And so these noble-hearted mothers and children had toiled uncomplainingly at garden, vineyard, and loom; had tended flocks of goats and cattle; and had harvested the hay and grain. For Bellerivre, walled in between the river Eisen and the snowy capped Pyrenees, was a fertile valley on which, in spite of the tragedy of national warfare, the sun seemed ever to shine. It was a mere dot of a place, with a vine-covered chapel, a low white convent tucked away among the hills, and a scattering of houses. In the centre of the town stood La Maison de Sainte Genevieve, the home of Monsieur le CurÉ, the much loved parish priest, who although bent and white-haired was the friend, counselor, and teacher of both young and old. The little schoolhouse where he had been accustomed to meet the children was, however, now closed; for in these troublous war days boys and girls had far more important duties to perform than to learn lessons. There were the great vineyards that striped the hills—these must not perish for want of care; then there were the gardens and hay-fields.

But none of these things, vital as they appeared, were of first importance in the community. It was from quite a different source that the peasants of Bellerivre derived their livelihood—a source peculiar if one was unfamiliar with it, but which had been the primary interest of the valley ever since its people could remember. They raised silkworms!

Not only did the father of Marie and Pierre earn his living thus, but so also did most of the other fathers in that green valley. As long ago as the boy and girl had been old enough to walk they had toddled out into the sunshine and helped gather mulberry leaves; and they had not been much older than this before they had learned exactly what kind of leaves the tiny spinners liked best to eat. The precious grove of white mulberry trees had been planted years before by M. Bretton, and had been cherished with greatest care ever since. Each season new trees had been added and so spaced that their roots might have room to spread. Around each tree a trench was dug to hold the moisture. Some of the trees had been raised from seed and transplanted into the mulberry grove when they were three years old; others had been rooted from slips or cuttings—a much quicker and less troublesome process. It was always necessary to have some new trees at hand that the very young silkworms might have tender leaves to feed upon.

How strange it was that out of the vast variety of vegetation these tiny creatures would eat nothing but mulberry leaves! Over and over again, M. Bretton told his children, people had experimented with the leaves of other plants—with lettuce, spinach, and various of the greens from the garden. But it was useless. The wee spinners scorned every such offering. One woman, it is true, had succeeded in raising a few worms on witch-grass; but they had not prospered, the silk from their cocoons proving poor. Mulberry leaves they craved and mulberry leaves they must have. In time the French peasants as well as the silk raisers of other nations abandoned their experiments and went to learning how to grow mulberry trees, studying with care not only which mulberry was best for their silkworms but also which of the species flourished most successfully in the soil of their particular country.

The more they investigated the more varieties of mulberries came to light. There was the Tartarica, or Tartar mulberry, found on the Volga; the Papyfera, or paper mulberry, from Japan; the Chinese mulberry; and the more common varieties of red, black, and white mulberry. To the soil of southern France the so-called white mulberry tree seemed best adapted, and therefore the French peasants began cultivating it extensively, mingling with it, however, some of the rarer Chinese cuttings when these could be secured.

Many a lesson did the people learn about the mulberry tree while they were perfecting its growth! They found the leaves could be reached much more easily if the top of the tree was clipped so that it would grow low and bushy; this enabled children to harvest the leaves, and did away with expensive labor. But because of the luxuriant climate of France and Italy the trees of those countries could seldom be kept low, and usually gatherers had to use ladders to reach the leaves—a process by which many of them were injured and rendered useless. As no silkworm would touch a bruised leaf much of the crop was wasted. In China, where the trees seldom grew beyond the size of shrubs, the conditions for gathering perfect leaves were ideal; especially as the Chinese cut away much of the under part of the trees, so that the gatherers might go in beneath them. In addition to these interesting facts people discovered that if a single twig was broken from the mulberry tree several new shoots would branch out in its place. This was surely a valuable thing to know. Moreover, they learned that the leaves of the white mulberry were the most tender; that those of the red ranked next; and that the black came last in delicacy. Few French or Italian people used the black, but in the colder countries, where it flourished better than did other kinds, it was used almost entirely. Another delightful discovery of the sericulturists, as silkworm raisers are called, was that when their mulberry trees were once properly planted they would, with good care, live to a marvelous old age—some of them even reaching the dignity of two or three hundred years. But unless snails and other destructive grubs were kept away the trees would not thrive. The finer and more carefully grafted they were the greater the damage resulting from hungry insects. In contrast the wild mulberry with its acid and bitter sap presented far less temptation and therefore lived longer than did the cultivated species.

This and many another lesson did the father of Marie and Pierre have to learn before he could successfully raise mulberry trees—to say nothing of silkworms. He must know how to prepare the mulberry seeds by crushing the fruit, covering the pulp with water, and separating the seeds from the waste part of the berry. He must know, too, how to spread the seeds upon cloth and lay them in the sun to dry, after which they were put away in covered jars, secure from air and moisture, and stored in some dark place until needed for planting.

To Marie and Pierre, brought up amid the environment of many a mulberry grove, these facts were an old story, and how fortunate it was that this was so. Now that their father and Uncle Jacques had gone to the war most of the care of the silkworms would fall to them. There was, to be sure, Josef the old gardener—he could give advice; but he was too old and crippled to do much work.

And therefore it was the two children, together with their mother, who were planning for their first harvest of cocoons, and were eagerly awaiting the unfurling of the mulberry leaves before beginning to hatch out their crop of silkworm eggs. How anxiously they had watched the trees! How eagerly scanned the swelling buds! Ah, it could not be long now. Was not the river a torrent from the melting of the winter's snows? Was not the sun warmer, the heaven bluer, the ground fragrant as if newly awake? Soon the mulberry trees would be sending forth their leaves. Until they did, however, it would be useless to hatch the eggs so carefully laid away, for there would be no food to give the ravenous little spinners should they rouse from their long sleep.

And so Marie, and Pierre, and their mother strove to be patient, contenting themselves in the meantime with preparing the empty rooms of the silk-house, where the caterpillars were to be raised. Many a time they had not only seen this done but had assisted in the process. Every step of the work was familiar. They knew well that the labor of making the place immaculate was far from wasted, for unless the rooms were spotless the fastidious spinners would either sicken and die, or would refuse to fashion their wonderful webs.

M. Bretton, who had spent a good portion of his slender income in constructing the up-to-date shelter that housed his caterpillars, often laughingly declared that their accommodations were far more luxurious than were those where his own family lived. Nevertheless it was money well invested, he argued, since already he had got back from the sale of his cocoons many times over what the plant had cost him. So successful had he been that his example had been followed by many of his more prosperous neighbors until now Bellerivre, tiny as it was, could boast as fine equipment for sericulture as could be found in all France.

Poor M. Bretton! How proud he had been of his handiwork! How modestly exultant over his good fortune! And now that he had been forced to abandon it all and go to the Great War it was unthinkable to his wife and children that they should not take up his work and strive to carry it on. Nay, the very bread they ate depended upon their doing so.

Hence do you marvel that Marie, Pierre, and Madame Bretton labored early and late and denied themselves many things they wanted, that instead the money might be spent to further the industry that M. Bretton had cherished? And since what we work for becomes the centre of our interests it logically followed that all three of them found their task an absorbingly fascinating one. Playtime and study were cast cheerfully aside, and in place of them the boy and girl received each day the more vital compensations that come from unselfishness and hard work.

It was Marie who first detected that the buds near the ends of the mulberry branches were opening.

As she and Pierre drove the flock of goats down the steep mountain trail which led from the plateau where the pasture lay she glanced across the valley. Against the blue sky a tracery of delicate green was showing.

"Pierre!" she cried, "see! The mulberry buds are awaking! Look! Do you not catch that bit of color against the clouds? We will wait no longer. Let us tell Mother to take the silkworm eggs out of the dark room and put them where it is light. Soon there will be plenty of new leaves. Hurrah, Pierre!"

With a rush Marie bounded past her brother and ran down the narrow path scattering the goats before her in every direction, and sending Hector racing homeward with yelps of delight.
