Note 4 — NATURAL HISTORY OF THE ITALIAN YELLOW ALP-BEE. (Apis helvetica.)

You must endeavour to insert the queen-cells in the middle of a comb, where the most of the bees gather; it is done best by cutting a diamond-shaped piece out of the comb, and then, loosely inserting the queen-cell cut to a similar shape. If it were inserted in the lower edge, the bees could not cover it on the approach of cold weather, and the cell would become cold and the bee perish.
