Hector St. John, in his Letters, gives the following curious account of the method which he employed in discovering Bees in our woods in early times: Provided with a blanket, some provisions, wax, vermilion, honey, and a small pocket compass, he proceeded to such woods as were at a considerable distance from the settlements. Then examining if they abounded with large trees, he kindled a small fire on some flat stones, close by which putting some wax, and, on another stone near by, dropping distinct drops of honey, which he encircled with the vermilion. He then retired to carefully watch if any Bees appeared. The smell of the burnt wax, if there were any Bees in the neighborhood, would unavoidably attract them; and, finding the honey, would necessarily become tinged with the vermilion, in attempting to get at it. Next, fixing his compass, he found out the direction of the hives by the flight of the loaded Bees, which is invariably straight when they are returning home. Then timing with his watch the absence of the Bee till it would come back for a second load, and recognizing it by the vermilion, he could generally guess pretty closely to the distance traversed by it in the given time. Knowing then the direction and the probable distance, he seldom failed in going directly to the right tree. In this way he sometimes found as many as eleven swarms in one season.[687] The shepherds of the Alps, as we learn from Sausure quoted in the Insect Miscellanies, as soon as the snows are melted on the sides of the mountains, transfer their flocks from the valleys below to the fresh pasture revived by the summer sun, in the natural parterres and patches of meadow-land formed at the foot of crumbling rocks, and sheltered by them from mountain storms; and so difficult sometimes is this transfer to be accomplished, that the sheep have to be slung by means of ropes from one cliff to another before they can be stationed on the little grass-plot above.[688] A similar artificial migration (if we may use the term), continues the author of the Miscellanies, is effected in some countries by the proprietors of Beehives, who remove them from one district to another, that they may find abundance of flowers, and by this means prolong the summer. Sometimes this transfer is performed by persons forming an ambulatory establishment, like that of a gipsy horde, and encamping wherever flowers are found plentiful. Bee-caravans of this kind are reported to be not uncommon in some districts of Germany;[689] and in parts of Greece,[690] Italy, and France,[691] the transportation of Bees was practiced from very early times. But a more singular practice in such transportation was to set the Beehives afloat in a canal or river, and we are informed that, in France, one Bee-barge was built of capacity enough for from sixty to one hundred hives, and by floating gently down the river, the Bees had an opportunity of gathering honey from the flowers along the banks.[692]
