And now, with considerable trepidation, and with something verging upon veritable awe, I approach a subject that I feel myself scarcely competent to handle. Fraught with the deepest interest to every new-chum, and a matter of no light concern to even the oldest colonist, it is one that demands an abler and more facile pen than mine to do full justice to it. Some one has boldly asserted that, throughout the infinite treasure-house of Nature, every separate and single thing has its particular and well-defined purpose. Without attempting to dispute a proposition so emphatically and dogmatically brought forward, it will be sufficient for me to say that men have asked in shuddering horror, and must still continue to ask, what part in the economy of creation is the sphere of duty or usefulness of that malignant thing we call the KAURI-BUG.[5] We do not know whether this insect is known to naturalists or not. That is a slight matter, and not particularly pertinent to the question of its interest for us. We believe, however, that no naturalist has yet been found of sufficiently ardent temperament, and of sufficiently hardy nerves, to attempt to classify or examine this most infamous of bugs. Appearances are deceptive very often; they are so in this instance. Nothing could look more innocent and inoffensive than the kauri-bug, yet few insects rival it in crime. It is an oval shape, anything under and up to the size of a crown piece. It is flat, black, hard, and shiny, and resembles a cross between the English black-beetle and the woodlouse or slater. It stinks. That is all it does, but it is enough. Look at it, and it is harmless enough. But tread on it, touch it, disturb it never so slightly, and instantly the whole surrounding atmosphere is permeated with a stench more infernally and awfully horrible than anything else this side of the Styx! The kauri-bug inhabits dead-wood of various kinds, but chiefly does it love that of the tree from which it derives its name. It invades houses built with open joints like ours in regiments and battalions, bringing all its family and luggage with it. The best class of houses are here built in a fashion styled bug-proof, but even they cannot wholly exclude this fearful thing. It comes in hidden in the firewood, and once in the house it stops there, since no one is courageous enough to turn it out. It appears to be indifferent as to whether the house is new or old, well-built or ruinous. If the structure is of kauri timber the kauri-bug will be there, and it will put up with any other wood if kauri timber is not available. It is one of the peculiar products indigenous to Northern New Zealand, and it is the least attractive of all.
