During the winter daily weights were taken and recorded. On the 19th of May, 1920, the number of.bees, the amount of brood and the amount of honey were again determined. This date is two weeks later than the one on which the bees were weighed in 1918-19, and each colony should have shown several thousand more bees this year on the 19th of May than it did last year on the 4th of May. In 1918-19 the one-story unpacked hive in the windbreak gained 313 bees, while the packed hive in the windbreak gained 24,844; but during 1919-20 the one-story unpacked hive in the windbreak gained 10,000, while the packed hive, similarly placed, gained only 3,700. In 1918-19 the two-story hive in the windbreak gained 5,936, whereas in 1920 it gained 8,125. These results would seem to overthrow any evidence that we may have had in the past as to the value of winter protection, especially when we consider the fact that the packed hive in 1918-19 had 24,331 more bees than the unpacked hive, while in 1919-20 it had 6,300 less. This would seem to indicate that the packing had not been of any great value to it, especially when the unpacked one-story hive had five frames of brood, while the packed hive had only three frames. Had it not been for the fact that daily records of the changes of weights were kept, those results would have been very disconcerting, and extremely hard to account for, but upon turning to the daily record we found that on April 20 the packed hive reached its lowest weight. From then until the 19th of May the gains and losses ranged from nothing up to an eighth of a pound, showing that on April 20 the winter stores were exhausted in that colony, and from that time forward they were barely able to secure enough nectar from the field to even maintain the existence of the colony. On the 19th of May, when the colony was weighed, no honey at all was found in the packed hive, while in the one-story unpacked hive there remained three and one-half pounds of unconsumed stores. The unpacked hive had five frames of brood, whereas the packed hive had only about three. To all ordinary appearances the packed hive was a good, strong colony of bees on the 19th of May, and anyone would have been justified in thinking that it had wintered well. However, when the fact is taken into consideration that during the previous year this colony gained 24,844 bees between the fall and spring, and this year only gained 3,700; we can see that something was radically wrong. As the one-story unpacked hive contained five frames of brood, while the packed hive only had three frames, we can understand why this weakened condition was brought about. On the 19th of April, when the stores were exhausted, the queen in the packed hive did not lay as many eggs as the one in the unpacked hive. To all appearances this colony had wintered well, yet when we consider that the date of weighing was two weeks later than the previous year, and that during these two weeks the queen should have deposited from 30,000 to 40,000 eggs, which would have filled six to eight frames of brood, when as a matter of fact it only had three frames, it showed plainly that the queen was seriously affected by the shortage of stores. Had we not the daily records of the changes in weightsin these colonies we would never have known why this colony did so poorly. Although in this article I have spoken of one colony, the same fact holds true for the rest of the colonies which became low in stores.
