Balsamifera_) and the Balm of Gilead, (_Populus Candicans_). By boiling the buds of these trees, an aromatic resin or gum may be obtained, (used sometimes for making salve;) the odor is very similar to that emitted by propolis, when first gathered by the bees, or by heating it afterwards. In the absence of facts, we are apt to substitute theory. This appears to me to be very plausible. Yet I am ready to yield it as soon as facts decide differently. Perhaps not one bee in a thousand is engaged in collecting this substance--there being so few may be one reason why they are not often detected, yet few as they are, a few of us should set about close observation; something certain might decide. Apiarian science is sadly neglected; a large amount of error is mixed up with truth, that patient, scrutinizing investigation must separate. REMARKS. I feel anxious to get to the practical part of this work, which I hope will interest some readers who care but little about the natural history. I shall begin with spring, and will now endeavor to mix more of the practical with it, as we proceed to the end of the year. In order to illustrate some points of practice, I may have occasion to repeat some things already mentioned. CHAPTER VII. THE APIARY. ITS LOCATION. In the location of the apiary, one important consideration is, that it is convenient to watch in the swarming season; that the bees may be seen at any time from a door or window, when a swarm rises, without the trouble of taking many steps to accomplish it; because if much trouble is to be taken, it is too often neglected. Also, if possible, the hives should stand where the wind will have but little effect, especially from the northwest. If no hills or building offer a protection, a close, high board fence should be put up for the purpose. It is economy to do it--bees enough may be saved to pay the expense. During the first spring months, the stocks contain fewer bees than at any other season. It is then that a numerous family is important, for the purpose of creating animal heat to rear the brood, if for nothing else. One bee is of more consequence now than a half dozen in midsummer. When the hive stands in a bleak place, the bees returning with heavy loads, in a high wind, are frequently unable to strike the hive, and are blown to the ground; become chilled, and die. A chilly south wind is equally fatal, but not so frequent. When protected from winds, the hives may front any point you choose; east or south is generally preferred. A location near ponds, lakes, large rivers, &c., will be attended with some loss. Hard winds will fatigue the bees when on the wing, often causing them to alight in the water; where it is impossible to rise again until wafted ashore, and then, unless in very warm weather, they are so chilled as to be past the effort. I do not mention this to discourage any one from keeping them, when so situated, because some few must keep them thus or not at all.
