finement is less as one proceeds southward, and limited to a 
few days at a time in the far Southern States, the winter 
consumption of stores increases rather than diminishes 
going southward, probably owing to greater winter activity 
of the bees. Little winter protection is provided for bees 
where not absolutely needed. Practically none is given in 
the Southern States, and but little in the middle tier, but in 
the far Northern States it is the general rule to pack or cellar 
the bees. Favorable methods of packing and the extent to 
which used in the different States are indicated in the table.
