Sometimes the young men fell a tall straight fir in the woods and set it up on a height, where the girls deck it with nosegays, wreaths of leaves, and red ribbons. Then brushwood is piled about it, and at nightfall the whole is set on fire. While the flames break out, the young men climb the tree and fetch down the wreaths which the girls had placed on it. After that lads and lasses stand on opposite sides of the fire and look at one another through the wreaths to see whether they will be true to each other and marry within the year. Also the girls throw the wreaths across the flames to the men, and woe to the awkward swain who fails to catch the wreath thrown him by his sweetheart. When the blaze has died down, each couple takes hands and leaps thrice across the fire. He or she who does so will be free from ague throughout the year, and the flax will grow as high as the young folks leap. A girl who sees nine bonfires on Midsummer Eve will marry before the year is out. The singed wreaths are carried home and carefully preserved throughout the year. During thunderstorms a bit of the wreath is burned on the hearth with a prayer; some of it is given to kine that are sick or calving, and some of it serves to fumigate house and cattle-stall, that man and beast may keep hale and well. Sometimes an old cart-wheel is smeared with resin, ignited, and sent rolling down the hill. Often the boys collect all the worn-out besoms they can get hold of, dip them in pitch, and having set them on fire wave them about or throw them high into the air. Or they rush down the hillside in troops, brandishing the flaming brooms and shouting. The stumps of the brooms and embers from the fire are preserved and stuck in cabbage gardens to protect the cabbages from caterpillars and gnats. Some people insert charred sticks and ashes from the midsummer bonfire in their sown fields and meadows, in their gardens and the roofs of their houses, as a talisman against lightning and foul weather; or they fancy that the ashes placed in the roof will prevent any fire from breaking out in the house. In some districts they crown or gird themselves with mugwort while the midsummer fire is burning, for this is supposed to be a protection against ghosts, witches, and sickness; in particular, a wreath of mugwort is a sure preventive of sore eyes. Sometimes the girls look at the bonfires through garlands of wild flowers, praying the fire to strengthen their eyes and eyelids. She who does this thrice will have no sore eyes all that year. In some parts of Bohemia they used to drive the cows through the midsummer fire to guard them against witchcraft.
In Slavonic countries, also, the midsummer festival is celebrated with similar rites. We have already seen that in Russia on the Eve of St. John young men and maidens jump over a bonfire in couples carrying a straw effigy of Kupalo in their arms. In some parts of Russia an image of Kupalo is burnt or thrown into a stream on St. John's Night. Again, in some districts of Russia the young folk wear garlands of flowers and girdles of holy herbs when they spring through the smoke or flames; and sometimes they drive the cattle also through the fire in order to protect the animals against wizards and witches, who are then ravenous after milk. In Little Russia a stake is driven into the ground on St. John's Night, wrapt in straw, and set on fire. As the flames rise the peasant women throw birchen boughs into them, saying, May my flax be as tall as this bough! In Ruthenia the bonfires are lighted by a flame procured by the friction of wood. While the elders of the party are engaged in thus churning the fire, the rest maintain a respectful silence; but when the flame bursts from the wood, they break forth into joyous songs.
As soon as the bonfires are kindled, the young people take hands and leap in pairs through the smoke, if not through the flames; and after that the cattle in their turn are driven through the fire.
In many parts of Prussia and Lithuania great fires are kindled on Midsummer Eve. All the heights are ablaze with them, as far as the eye can see. The fires are supposed to be a protection against witchcraft, thunder, hail, and cattle disease, especially if next morning the cattle are driven over the places where the fires burned. Above all, the bonfires ensure the farmer against the arts of witches, who try to steal the milk from his cows by charms and spells. That is why next morning you may see the young fellows who lit the bonfire going from house to house and receiving jugfuls of milk. And for the same reason they stick burs and mugwort on the gate or the hedge through which the cows go to pasture, because that is supposed to be a preservative against witchcraft. In Masuren, a district of Eastern Prussia inhabited by a branch of the Polish family, it is the custom on the evening of Midsummer Day to put out all the fires in the village. Then an oaken stake is driven into the ground and a wheel is fixed on it as on an axle. This wheel the villagers, working by relays, cause to revolve with great rapidity till fire is produced by friction. Every one takes home a lighted brand from the new fire and with it rekindles the fire on the domestic hearth. In Serbia on Midsummer Eve herdsmen light torches of birch bark and march round the sheepfolds and cattle-stalls; then they climb the hills and there allow the torches to burn out.
Among the Magyars in Hungary the midsummer fire-festival is marked by the same features that meet us in so many parts of Europe. On Midsummer Eve in many places it is customary to kindle bonfires on heights and to leap over them, and from the manner in which the young people leap the bystanders predict whether they will marry soon. On this day also many Hungarian swineherds make fire by rotating a wheel round a wooden axle wrapt in hemp, and through the fire thus made they drive their pigs to preserve them from sickness.
