L E Snelgrove M.A  M.Sc. and several titles in the bee world lived in
Somerset, Southern England,  published his book SWARMING.  IT'S CONTROL AND
PREVENTION, which ran to nine editions from around 1934 to1946.  It will be
found in any good beekeeping library.  A new re-print is available from

The method involves extra brood chambers and a special screen board
splitting the stock and  containing six apertures which are alternately
shut or opened at different times.  I looked at the method many years ago 
and rejected it as too complex for the number of hives I was running.  
Ideal, perhaps, for someone with few hives and time to spare.  I settled
long ago for routine 7 to 9 day inspections and a simple form of Demaree
when swarming was started.              Sid P.
