The bee keeper can easily gather from these remarks, the means upon which I most rely, to protect my colonies from the bee-moth. Knowing that strong stocks supplied with a fertile queen, are always able to take care of themselves, in almost any kind of hive, I am careful to keep them in the state which is practically found to be one of such security. If they are weak, they must be properly strengthened, and confined to only as much space as they can warm and defend: and if they are queenless, they must be supplied with the means of repairing their loss, or if that cannot be done, they should be at once broken up, (See Remarks on Queenlessness, and Union of Stocks,) and added to other stocks. It cannot be too deeply impressed upon the mind of the bee-keeper, that a small colony ought always to be confined to a small space, if we wish the bees to work with the greatest energy, and to offer the stoutest resistance to their numerous enemies. Bees do most unquestionably, "abhor a vacuum," if it is one which they can neither fill, warm nor defend. Let the prudent bee-master only keep his stocks strong, and they will do more to defend themselves against all intruders, than he can possibly do for them, even if he spends his whole time in watching and assisting them. It is hardly necessary, after the preceding remarks, to say much upon the various contrivances to which so many resort, as a safeguard against the bee-moth. The idea that gauze-wire doors, to be shut daily at dusk, and opened again at morning, can exclude the moth, will not weigh much with one who has seen them flying and seeking admission, especially in dull weather, long before the bees have given over their work for the day. Even if the moth could be excluded by such a contrivance, it would require, on the part of those who rely upon it, a regularity almost akin to that of the heavenly bodies in their courses; a regularity so systematic, in short, as either to be impossible, or likely to be attained but by very few.
