July 9/58/ I believe Bees tend to make a flat walls for each separate planes of cell in its proper position; & that the circumferential ribbon represents theoretically such many walls with angle filled up. The arching of free end of wall is not true in any apparent form throwing up of material, the arch being common to one or two walls —

In the final cell, however, there is no intermediate wall for each plane, but mere saucer, which is added to. This is because 1 Bee begins by itself.

Waterhouse is wrong in saying that cells must be in contact to be formed angularly - what is necessary the Bees shd have standing room to tend to sweep their spheres & make intermediate wall. The hexagon on Zinc rod, good to show that Bees form rough walls on very proper principle

Bees make intermediate walls both by excavation & building up, but then build too thick.
