Look at the 1892 ABJ, page 545. You may want to read the 1918 Gleanings in Bee Culture, page 338, article by Iona Fowles in which she discusses the history of Demaree's plan.
Thanks, Iona's article was interesting, although I disagree with many of her conclusions. Be that as it may, from what I can see, then, all these books and web sites proclaiming that the Demaree method was published in 1884 are all *wrong*. The method that he published in 1884 was nothing like demareeing as it was practiced by 1910.
In my own little beek library, demareeing is mentioned three times pre-1925, namely:
* 1911, CC Miller, 364 pages - Fifty Years Among the Bees
* 1916, Frank C Pellett, 329 pages - Productive Bee-Keeping, Modern methods of production and marketing of honey
* 1921, HJ Baker, 16 pages - Spring Management of Bees
Even in Miller's and Pellet's books, the descriptions of demareeing are pretty close to what most modern books refer to as demareeing (apart from the twist of adding supers between the brood nest and the queen excluder, to remove the nurse bees even further from the queen):
If I understand correctly, Iona's article precedes the proliferation of separator-based methods (e.g. Snelgrove's), which explains her comment that
"If every plan in which brood is raised to an upper story has the right to [the name 'Demaree method'], then almost every plan except swarming, dividing, or dequeening should be so designated."Demaree's 1892 post (or: article?) comes close enough to modern demareeing for me to consider it the origin:
The only difference is that most modern books describing the method do not mention placing the brood frames in the middle of the box, with pollen/honey frames on the outside edges.
Iona's article mentions a post by Demaree in 1895, but I could not find it. The only mention in 1895's American Bee Journal that I could find is this one (page 633), which doesn't say anything new:
(and unfortunately one needs a subscription to search the Canadian Bee Journals of the 1890s).
