nizant of the situation and ere working in close cooperation with the beekeepers 
in the affected counties to eradicate particularly parafoulbrood, a brood disease 
of bees about which relatively little is known. Semples of parafoulbrood have 
also been received from Florida where, in previous years, the disease has been

stock has sufficed to keep the disease under control.

Mr, Whitcomb says, "The actual days column shows the number of days that the 
last bee in the cage Live‘, t is valueless, so far as determining the value of 
a fooc is concerned, The cormuted lencth of life is obtained by dividing the
