Hello Dee & All, Dee said: Want to let Bob Harrison know that I liked his informative reply. Thanks Dee! I have tried to give insight to the list on many topics concerning the commercial and commercial migratory beekeeper. Every year at this time I make time to read old beekeeping books. Today I was rereading a 1913 edition of the 1888 "Langstroth on the Hive & Honey Bee" Because the book is now on line in the new virtual library (Cornell Univ..)all can follow along. My copy is not pristine and in poor condition but very readable. For those unfamiliar with the text I will share the fact that each section in numbered and in parenthesis is often another number which directs the reader to another section of similar interest and at times several sections. On page 103 of the above book under the section "comb" Langstroth makes an observation which might spark a discussion from my friend and fellow reader of old bee books Dee Lusby. The number section in my copy is 217. Langstroth quote from his book: "The cells in which workers are reared are the smallest. Those in which the drones are reared are larger. *It is generally admitted that five worker-cells measure about a linear inch, or twenty -five cells to the square inch, BUT THIS IS INCORRECT. IF five worker cells measured exactly an inch, the number contained in a square inch would be about twenty-nine. As they are usually somewhat larger, the average number in a square inch IS a trifle over twenty-seven." Using my calculator the above puts cell size at the time of the books writing (1888) *according to Langstroth* as closer to 5.1mm to 5.2mm. than as has been suggested by 4.9ers as 4.9mm. I have read many old bee books and Langstroth's book before but never remember reading the above observation by Langstroth. Langstroth was noted for his accurate observations in the bee hive. I believe Langstroth is the only writer of old bee books to question the statement which is common in every other old bee book I have read which states worker cells ARE "five cells to the inch". It is interesting that Langstroth clearly says " five cells to the inch is INCORRECT". Interesting that over a hundred years later we still can not agree on what is the correct size of worker cells today and especially not what was the correct size for the 1880's. I hope Ed is doing better Dee and thought I would give you and the 49 ers something to ponder. Merry Christmas & Happy Holidays to the list!
