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.[437] 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.[438] In the sixteenth century Martin of Urzedow, a Polish priest, denounced the heathen practices of the women who on St. John's Eve (Midsummer Eve) kindled fires by the friction of wood, danced, and sang songs in honour of the devil.[439] [The Midsummer fires among the Letts of Russia; Midsummer Day in ancient Rome.]
