The rest of the family, including the mother—and she not the least eager—usually go with us. One cannot have too many eyes when the pit becomes deep and one has to observe from a distance the minute documents exhumed by the spade. What the one misses the other perceives. Huber, [28] when he went blind, studied the bee through the intermediary of a clear-sighted and devoted adjutrix. I am even better-off than the great Swiss naturalist. My sight, which is still fairly good, although exceedingly tired, is aided by the deep-seeing eyes of all my family. I owe to them the fact that I am able to pursue my researches: let me thank them here. We are on the spot early in the morning. We soon find a burrow with a large mole-hill formed of cylindrical stoppers forced out in one lump by blows of the rammer. We clear away the mound and a pit of great depth opens below it. A useful reed, gathered on the way, serves me as a guide, diving lower and lower down. At last, at about five feet, the reed touches bottom. We are there, we have reached Minotaurus’ chamber. The pocket-trowel prudently lays things bare and we see the occupants appear: the male first and, a little lower, the female. When the couple are removed, a dark, circular patch shows: this is the end of the column of victuals. Careful now and let us dig gently! What we have to do is to cut away the central clod at the bottom of the vat, to isolate it from the surrounding earth and then, slipping the trowel underneath and using it as a lever, to extract the block all in a lump. There! That’s done it! We possess the couple and their nest. A morning of arduous digging has procured us those treasures: Paul’s steaming back could tell us at the price of what efforts. This depth of five feet is not and could not be constant; numbers of causes induce it to vary, such as the degree of freshness and consistency of the soil traversed, the insect’s passion for work and the time available, according to the more or less remote date of the laying. I have seen burrows go a little lower; I have seen others reach barely three feet. In any case, Minotaurus, to settle his family, requires a lodging of exaggerated depth, such as is dug by no other burrowing insect of my acquaintance. Presently we shall have to ask ourselves what are the imperious needs that oblige the collector of sheep-droppings to reside so low down in the earth. Before leaving the spot, let us note a fact the evidence of which will be of value later. The female was right at the bottom of the burrow; above her, at some distance, was the male: both were struck motionless with fright in the midst of an occupation the nature whereof we are not yet able to specify. This detail, observed repeatedly in the different burrows excavated, seems to show that each of the two fellow-workers has a fixed place.
