Fig. 25 (Hive frames) shows a side view of the frames C, C, C, partition boards p, P, and the V's.
Stand on the side of the hive, in front of the partition board P [on the right], for example. After detaching the first V, pull that partition board at its middle; thanks to the hinges it will fold in two, and will easily detach itself from the hive. Replace it, one step closer to you, and after replacing it, check to see that it's between the two black spots M, N, which serve to locate its vertical [sic - horizontal (*)
] position. We see in fig. 25 then, the partition board in it's new position.
Then detach V no. 2, then frame no. 1; after checking it, you place that frame in the notch where the partition board was. Put a V between that frame and the partition board. Continue the same process with all of the frames.
Here is another method that is preferably used to add or remove one or more frames from a colony. One inclines towards oneself the partition board without removing it,
fig. 26 (Frames as seen from the side);
the same thing is done for each frame, adding the V's as in the first method; and we continue until we have reached the frame we want to remove. After removing it, advance the other frames and partition board a notch. To add a frame to a hive, we operate as above, with the only difference being that, at the same time as the frames are inclined, they are moved one step until you reach the position where you want add a new one. We must be careful when removing frames, not to rub them against each other, which irritates the bees.
