There is nowa strong tendency toward building standardwinter packing eases to hold four inches ofpacking below, six inches on the sides andeight to ten inches on top, though in somecases more than this is used. Colonies prop-erly packed in such winter cases have beenwintered well year after year in the ex-treme northern part of the United States andill Canada. Beekeepers cannot well be ex-pected to agree upon the question of thethickness of packing, for in aslocation thatis well protected from prevailing winds twoor three inches of packing may afford asmuch protection as six or eight inches inanother location badly exposed to strongwinds. Since it costs but little more tobuild a packing case a couple of incheslonger and wider and since the packing ma-terial is usually not expensive, it is betterto err on the safe side and provide for am-ple packing. Material for Packing. It is well to remember that the heat-re-. l>oiilile-\\.-ille(l hivis with ImiU in jiiickiiit;- ;ire ousily prepared Ior wiiitoi. 0(-T(ini;i:, 192-J OliEANINGS IN BMK CULTURE 63<) ; inuinitics of llic packing materialare in the minute uir spaces vvitliin this m;iterial. If material too coarse, such as straw,excelsior, or coarse planer sliavings, is used,the air spaces being large will permit somecirculation and tlierefore a more rapid lossof heat. Tlie packing material should befine enough to prevent this. For the samereason tlie space between the walls of adouble-walled hive should not be left un-packed. If the confined air in this spacecould not circulate there would be no needof packing, but the difference in the tem-perature of the inner and the outer wallscauses air currents within this so-calleddead-air space that result in a rapidloss of heat unless this space is filled withpacking. In this sense the function of thepacking material is to prevent the movement of the air betwe
