If the hive is of glass, it will warm up all the better, and as the combs are on frames, they cannot be melted or injured by the heat. It is a serious objection to most covered Apiaries, that they do not permit the hives to receive the genial heat of the sun at a period of the year when instead of injuring the bees, it exerts a most powerful influence in developing their brood.
This is one among many reasons why I have discarded them, and why I prefer to construct my hives in such a manner that they need no extra covering, but stand exposed to the full influence of the sun. I have known strong colonies which have survived the Winter in thin hives, to increase rapidly and swarm early, because of the stimulating effect of the sun; while others, deprived of this influence, in dark bee houses and well protected hives, have sometimes disappointed the hopes of their owners. Although my glass hives are very beautiful, and most admirably protected, still hives of doubled wood may often be built to better advantage by those who construct their own hives, and they can be made to furnish any desirable amount of protection.
Enclosed Apiaries are at best but nuisances: they soon become lurking-places for spiders and moths; and after all the expense wasted on their construction, afford, but little protection against extreme cold.
I have been thus particular on the subject of protection, in order to convince every bee keeper who exercises common sense, that thin hives ought to be given up, if either pleasure or profit is sought from his bees. Such hives an enlightened Apiarian could not be persuaded to purchase, and he would consider them too expensive in their waste of honey and bees, to be worth accepting, even as a gift. Many strong colonies which are lodged in badly protected hives, often consume in extra food, in a single hard winter, more than enough to pay the difference between the first cost of a good hive over a bad one. In the severe winter of 1851-2, many cultivators lost nearly all their stocks, and a large part of those which survived, were too much weakened to be able to swarm. And yet these same miserable hives, after accomplishing the work of destruction on one generation of bees, are reserved to perform the same office for another. And this some call economy!
