Descending into the Marum Volcano in Vanuatu, Intrepid explorers found an unusual way of staying warm this winter by spending Christmas day on an active volcano. British climber Chris Horsley, 22, and his friends Gareth Hawken, 30, Geoff Mackley, 50, and Bradley Ambrose, 36, from Auckland, New Zealand, hiked up the Marum Volcano, Vanuatu, on the morning of the 25th. Instead of passing the day with their families, the team climbed down a 1200ft cliff to get close to a flowing lake of lava. (Photo by Bradley Ambrose/Caters News)

The Last Bell (we mean the bell that informs the pupils about the beginning or the ending of the lessons) is the traditional feast of the Russian pupils who leave the school. The Last School Bell feast occurs in the end of May, when the school year has already finished, but the final examinations have not begun yet.

“The Labor Day Parade (or West Indian Carnival), is an annual celebration held on American Labor Day (the first Monday in September), in Crown Heights, Brooklyn, New York. Ms. Jessie Waddell and some of her West Indian friends started the Carnival in Harlem in the 1920s by staging costume parties in large enclosed places like the Savoy, Renaissance and Audubon Ballrooms due to the cold wintry weather of February. This is the usual time for the pre-Lenten celebrations held in most countries around the world. However, because of the very nature of Carnival, and the need to parade in costume to music, indoor confinement did not work well. The earliest known Carnival street parade was held on September 1, 1947. The Trinidad Carnival Pageant Committee was the founding force behind the parade, which was held in Harlem. The parade route was along Seventh Avenue, starting at 110th St.” – Wikipedia
