 with strong withes, to prevent their being destroyed by the bears, who are great devourers of honey. Bell learned, moreover, that the peasantry in these parts had a method of extracting the honey without destroying the bees; but the persons who gave him the information described the process so indistinctly that he could not understand it.

Their road now lay for many days through dark woods, interspersed at wide intervals with villages and cornfields. The cold daily became more and more intense; thick fogs hung upon the ground; the frost penetrated everywhere. The fingers and toes of those most exposed were frozen, and could only be restored to animation by being rubbed with snow. At length, on the 9th of December, they arrived at Solekampsky, famous for its great salt-works, which, if necessary, could not only have furnished all Russia, but several other countries also, with salt.

The value of this laniferous stone is said to have been discovered by a sportsman, who, happening one day to be in want of wadding in the woods, and observing the threadlike
