"cask" this entry states that "After filing, a plastic or wooden stopper called a shive is driven into the large bunghole on the belly, and a smaller one called a keystone is driven into the tap hole." In fact the keystone is driven into the tap hole before filling as the cask would leak otherwise.
Brilliant!! Ed Wray picked out that one. Don't know how I missed it. Ed's been doing a wonderful job working away at correcting, amending and adding to the thousands of pages of entries. This, I understand, is Ed. He's only up to D so far. Many have given up before that. Be strong, Ed. Martyn has been adding to the wiki today, too. W, P and S so far. And did you know the OCB has no entry for the worlds greatest selling beer? You do now.
Good work. 202 or 18.36% of the book's entries have now been corrected. Is the burst of entries because it is the Canadian Thanksgiving long weekend? Me, I am eating cold mac + cheese and watching Canadian three-down football myself. Because I am thankful for cold mac + cheese and Canadian three-down football. And Ed and Martyn.
