This bird, often called the bee-martin, is one of the fly-catchers, a very valuable family of birds, as they are wholly insectivorous, and do immense good by destroying our insect pests. The king bird is the only one of them in the United States that deserves censure. Another, the chimney swallow of Europe, has the same evil habit. Our chimney swallow has no evil ways. I am sure, from personal observation, that these birds capture and eat the workers, as well as drones; and I dare say, they would pay no more respect to the finest Italian Queen. Yet, in view of the good that these birds do, unless they are far more numerous and troublesome than I have ever observed them to be, I should certainly be slow to recommend the death warrant. THE TOADS. The same may be said of the toads, which may often be seen sitting demurely at the entrance of the hives, and lapping up the full-laden bees with the lightning-like movement of their tongues, in a manner which can but be regarded with interest, even by him who suffers loss. Mr. Moon, the well known apiarist, made this an objection to low hives; yet, the advantage of such hives far more than compensates, and with a bottom-board, such as described in the chapter on hives, we shall find that the toads do very little damage. MICE. These little pests are a consummate nuisance about the apiary. They enter the hives in winter, mutilate the comb, irritate, perhaps destroy, the bees, and create a very offensive stench. They often greatly injure comb which is outside the hive, destroy smokers, by eating the leather off the bellows, and if they get at the seeds of honey plants, they never retreat till they make a complete work of destruction. In the house and cellar, these plagues should be, by use of eat or trap, completely exterminated. If we winter on the summer stands, the entrance should be so contracted that mice cannot enter the hive. In case of packing as I have recommended, I should prefer a more ample opening, which may be safely secured by taking a piece of wire cloth or perforated tin, and tacking it over the entrance, letting it come within one-fourth of an inch of the bottom-board. This will give more air, and still preclude the entrance of these miserable vermin. (See Appendix, page 293). CHAPTER XX. CALENDAR AND AXIOMS. WORK FOR DIFFERENT MONTHS.[1] [Footnote 1: These dates are arranged for the Northern States, where the fruit trees blossom about the first of May. By noting these flowers, the dates can be easily changed to suit any locality] Though every live apiarist will take one, at least, of the three excellent journals relating to this art, printed in our country, in which the necessary work of each month will be detailed, yet it may be well to give some brief hints in this place.
