The form and size of frames, though not quite as various as the persons who use them, are still very different. Some prefer large frames. I first used one ten by eighteen inches, and afterward a shallow frame about seven by eighteen (Fig. 29). The advantage claimed for large frames is that there are less to handle, and time is saved; yet may not smaller frames be handled so much more dexterously, especially if they are to be handled through all the long day, as to compensate, in part at least, for the number? The advantage of the shallow frame is, as claimed, that the bees will go into boxes more readily; yet they are not considered so safe for out-door wintering. This is the style recommended and used by Mr. Langstroth, which fact may account for its popularity in the United States. Another frame in common use, is one about one foot square. I use one eleven inches square. The reasons that I prefer this form are, that the comb seldom breaks from the frame, the frames are convenient for nuclei, and save the expense of constructing extra nucleus hives, and that these frames permit the most compact arrangement for winter and spring, and thus enable us to economize heat. By use of a division board, we can, by using eight of these frames, occupy just a cubic foot of space in spring, and by repeated experiments I have found that a hive so constructed that the bees always cover the combs during the early cold weather, always gives the best results. As the honey season comes on more can be added, till we have reached twelve, as many, I think, as will ever be needed for brood. This was the size of frame preferred by Mr. Gallup, and is the one used by Messrs. Davis and Doolittle, and many others of our most successful apiarists. That this size is imperative is, of course, not true; that it combines as many desirable points as any other, I think, is true. For apiarists who are not very strong, especially for ladies, it is beyond question superior to all others. HOW TO CONSTRUCT THE FRAMES.
