MAIL INDUCTIO, an ancient custom for the priest and people of country-villages to go in procession to some adjoining wood on a May-day morning; and return in a kind of triumph, with a May pole, boughs, flowers, garlands, and other tokens of the spring. This May-game, or rejoicing at the coming of the spring, was for a long time observed, and still is in some parts of England; but there was thought to be so much heathen vanity in it, that it was condemned and prohibited within the diocese of Lincoln by the good old Bishop Grossthead.
