I now come to notice the use of the block-fronts on each side of the feeding-drawer, marked G. These two block-fronts answer many good purposes, and furnish the apiarian with several practical advantages: first, in the facility they afford of adding numbers to the establishment, as occasion may require, which is done without the least inconvenience or trouble to the apiarian, and without the least resentment from the native Bees; second, in affording to the Bees a place of egress when you are about to take from them one of the end-boxes; third, in the effectual and beautiful guard they furnish against robbers: for instead of the solid block, seen in the plate, a safety-block (of which a description will be given presently) may be substituted, which is so contrived that ten thousand Bees can with ease leave their prison and their sweets in the possession of the humane apiarian, without the possible chance of a single intruder forcing its entrance to rob the magazine or to annoy the apiarian. Perhaps this is the most pleasing part, and the most happy convenience attached to the boxes. Its origin was this: Whilst explaining to some scientific gentlemen at the National Repository the method to be pursued in the management of Bees in a set of collateral-boxes,--and, in particular, the manner of taking off a box of honey, it was objected--that, on removing the block-front and withdrawing the tin that opens a communication into the box above, though a passage would thereby be opened for the imprisoned Bees to get away, it would at the same time afford an opening and an opportunity--nay, be a sort of invitation for the Bees of other hives,--for strange Bees and robbers to get in, annoy, and destroy the native Bees, then subdued by having been imprisoned, and to plunder and carry away their treasures.
