Overcoats for bees the latest. Beltsville, Md., April 11. W.J. Nolan, Apiculturist of the Bee Culture Laboratory at National Agricultural Research Center here, is demonstrating to Miss Lorry Van Houten, how overcoats for bees protect these honey producers from howling winds of winter. Formerly the packing for double decked hives was sawdust and TA(?) paper, now these cold-blooded insects can huddle under overcoats consisting of double blankets, with an added canvas cover.
