Bark (botany) rope, used for example in the rigging of Viking age longships. Among the commercial products made from bark are cork, cinnamon, quinine (from the bark of Cinchona) and aspirin (from the bark of willow trees). The bark of some trees notably oak ("Quercus robur") is a source of tannic acid, which is used in tanning. Bark chips generated as a by-product of lumber production are often used in bark mulch in western North America. Bark is important to the horticultural industry since in shredded form it is used for plants that do not thrive in ordinary soil, such as epiphytes.
Bark at the Moon new remix of the album. This 2002 remixed version of the album was met with mixed reaction; many elements found in the original mix are not present in the remix, namely several lead guitar parts. In addition, the song "You're No Different" has an alternate ending (with the fade-out removed) and "Centre of Eternity" has an altered intro segment. This edition also included the bonus tracks "Spiders" and "One Up the 'B' Side", originally the B-side of the "Bark at the Moon" single. All lyrics and music by Ozzy Osbourne, Jake E. Lee, and Bob Daisley Bark at the Moon
