The trellised front has a south aspect and allows the sun’s rays to penetrate right into the dwelling. The opposite side, which faces north, consists of two shutters one above the other. They are movable and are kept in place by hooks or bolts. The top one opens for food to be distributed and for the cleaning of the cage; it is the kitchen-door for everyday use. It is also the entrance-gate for any new captives whom I succeed in bagging. The bottom shutter, which keeps the layer of earth in position, is opened only on great occasions, when we want to surprise the insect in its home life and to ascertain the condition of the progress underground. Then the bolts are drawn; the board, which is on hinges, falls; and a vertical section of the soil is laid bare, giving us an excellent opportunity of studying the Dung-beetles’ work. Our examination is made with the point of a knife and has to be conducted with the utmost care. In this way we get with precision and without difficulty industrial details which could not always be obtained by laborious digging in the open fields. Nevertheless, outdoor investigations are indispensable and often yield far more important results than anything derived from home rearing; for, though some Dung-beetles are indifferent to captivity and work in the cage with their customary vigour, others, who are of a more nervous temperament or perhaps more cautious, distrust my boarded palaces and are extremely reluctant to surrender their secrets. It is only once in a way that they fall victims to my assiduous wooing. Besides, if my menagerie is to be run properly, I must know something of what is happening outside, were it only to find out the right time of year for my various projects. It is absolutely essential therefore that our study of the insect in captivity should be amply supplemented by observations of its life and habits in the wild state. Here an assistant would be very useful to me, some one with leisure, with a seeing eye and a simple heart, whose curiosity would be as unaffected as my own. This helper I have: such an one indeed as I have never had before or since. He is a young shepherd, a friend of the family. He has read a little and has a keen desire for knowledge, so he is not frightened by the terms Scarabæus, Geotrupes, Copris or Onthophagus when I name the insects which he has dug up the day before and kept for me in a box.
