Hello Dan and All, The Thurber long cage construction and use are also described on page 61 of Roy's book. "Bee Chats, Tips and Gadgets". I treasure my copy. A Washington beekeeper posted a couple years ago on Bee-L they were going to start printing and selling the book again. P.F.(Roy) Thurber was an exceptional beekeeper. Roy's wife confided Roy would get up in the night trying to solve a particular beekeeping problem he was working on. The book is full of his many beekeeping inventions and collections of what he considered the best beekeeping articles he had read in various newsletters and magazines . Dadant published the original book in 1986 BUT Roy's wife Louise holds the copyright. Maybe time for a reprint. Sincerely, Bob Harrison
