June 11 -- A Hot day in the Old Towne...

On this day 11 June:

Barnabee's Day

FEAST OF ST. BARNABAS: Barnabas is the patron saint of farmers, and by English tradition (in which it is sometimes called Barnabee's Day) this is supposed to be the hottest day of the year.

It was usual in some churches to decorate the altars with garlands of flowers. In Hesket, an extensive parish of Cumberlandshire, England the Court of Inglewood Forest is held annually on June 11 in the open air. The suitors assemble by the highway-side at a place marked only by an ancient thorn, where the annual dues to the lord of the forest, compositions for improvements, etc., are paid; and a jury for the whole jurisdiction is chosen from among the inhabitants of twenty mesne manors who attend on this spot.
--William S. Walsh, Curiosities of Popular Customs, and of Rites, Observances, and Miscellaneous Antiquities (1897)
