"You are thinking of the Druids, who lived in old times in Britain and Gaul," replied Miss Harson, "and whose strange heathen rites were practiced in oak-groves; and they really did consider the tree sacred. These Druids have left their traces in some parts of England and France in rows of huge stones set upright; and wherever an immense stone was found lying on two others, in the shape of a table, there had been a Druid altar, where the priest offered sacrifices, often of human beings. So horrible may be a so-called religion that men themselves devise, and that has not come from the true God.
