When you suspect there may be a material change in the temperature of the room, look to the thermometer; if too cold, close the valves, if too warm open them more or less, as occasion may require; if that is not sufficient, open the door after dark, and close it again before light, and if that is not sufficient, throw in and spread over the floor a few bushels of snow or pounded ice. Many swarms will be benefited by being set out on their summer stands at the time of the January thaw, or in February, those that are besmearing their hives, that they may discharge themselves, which will cure most cases of diarrhœa, or dysentery as it is called--though there are real cases of diarrhœa, but not often. Thus we have passed over the most essential points in the wintering of bees. I will now proceed to give some, if not all of the necessary steps in their management in the spring. It is difficult to give the exact date at which they should be removed to their summer stands, but whenever it is done, it is not at all important that each swarm should be placed on the identical stand it had the previous season, neither is this precaution necessary if set out in the winter. In removing them from the cellar, it will first be necessary to close up the fly-hole and remove the chip or block from under the honey board--to confine the bees in the hive. Immediately after placing them upon their summer stands, if housed in special depositories, and perhaps about the same time or a trifle earlier if wintered out, the bottom boards should be cleaned of dead bees and other filth, it saves the bees much labor and no doubt conduces to their health.
