Note 1 — Chapter III · THE SACRED BEETLE: THE MODELLING

The arrangements made are as follows: I once more take the large glass jar. I cover the bottom with a layer of earth a few inches in thickness. To obtain the transparent workshop necessary for my observations, I fix a tripod on the earthy layer and, on this support, a decimetre1 high, I place a round deal slab of the same diameter as the jar. The glass-walled chamber thus marked out will represent the roomy crypt in which the insect works. In the edge of the deal slab, a hollow is cut, large enough to permit of the passage of the Sacred Beetle and her ball. Lastly, above this screen, I heap a layer of earth as deep as the jar allows.
