When bees are engaged in rapidly storing up honey in their combs, they may be seen, as _soon_ as they return from the fields, or from the feeding boxes, putting their heads at once into the cells, and disgorging the contents of their "honey-bags." Now that the contents of their sacs undergo no change at all, during the short time that they remain in them, I will not absolutely affirm, because I have endeavored, through this whole treatise, never to assert positively when I had not positive evidence for so doing: but that they can undergo but a _very slight_ change, must be evident from the fact that when thus stored up, the different kinds of honey or sugar can be almost if not quite as readily distinguished as before they were fed to the bees. The only perceptible change which they appear to undergo in the cells, is to have the large quantity of water evaporated from them, which is added from thoughtlessness, or from the vain expectation that it will be just so much water sold for honey, to the defrauded purchaser! This evaporation of the water from the honey by the heat of the hive, is about the only marked change that it appears to undergo, from its natural state in the nectaries of the blossoms; and it is exceedingly interesting to see how unwilling bees are to seal up honey, until it is reduced to such a consistency that there is no danger of its souring in the cells. They are as careful as to the quality of their nectar, as the good lady of the house is, to have the syrup of her preserves boiled down to a suitable thickness to keep them sweet. Let all who for any purpose whatever, feed bees, keep this fact in mind, and never add to the food which they give them, more water than is absolutely necessary. To do so, is a piece of as great stupidity as to pour a barrel of water into the sugar pans, for every barrel of sap from the maples, or juice from the canes! If a strong colony is set upon a platform scale, it will be found on a pleasant day, during the height of the honey harvest, to gain a number of pounds; if examined again, early next morning, it will be found to have lost considerably, during the night. This is owing to the evaporation of the water from the freshly gathered honey, and it may often be seen running down in quite a stream from the bottom-board.
