I notice the British referring to 'rebates' in relation to the groove on the inside top edge of the front and back panels of a standard bee box. As a former cabinetmaker, I am very familiar with the term 'rabbet' but have never heard of a 'rebate' except as a reference of returning a portion of a purchase price. I therefore wonder if the use of 'rebate' is an unique beekeeping word, a usage unique to the former British Empire (somehow not including Canada) or a common misspelling. I checked quickly online found this for 'rebate': http://www.dictionary.com/cgi-bin/dict.pl?db=web1913&term=rebate and this for 'rabbet': http://www.dictionary.com/cgi-bin/dict.pl?term=Rabbet I realise that there are other dictionaries out there, but I'd like to put the question to the list. allen http://www.internode.net/HoneyBee/ --- Good news is just life's way of keeping you off balance.
