The insect, in its buildings, has its own architectural rules, rules as unchangeable as anatomical peculiarities. Each group builds according to the same set of principles, conforming to the laws of a very elementary system of aesthetics; but often circumstances beyond the architect's control--the space at her disposal, the unevenness of the site, the nature of the material and other accidental causes--interfere with the worker's plans and disturb the structure. Then virtual regularity is translated into actual chaos; order degenerates into disorder. We might discover an interesting subject of research in the type adopted by each species when the work is accomplished without hindrances. The Banded Epeira weaves the wallet of her eggs in the open, on a slim branch that does not get in her way; and her work is a superbly artistic jar. The Silky Epeira also has all the elbow-room she needs; and her paraboloid is not without elegance. Can the Labyrinth Spider, that other spinstress of accomplished merit, be ignorant of the precepts of beauty when the time comes for her to weave a tent for her offspring? As yet, what I have seen of her work is but an unsightly bundle. Is that all she can do? I look for better things if circumstances favour her. Toiling in the midst of a dense thicket, among a tangle of dead leaves and twigs, she may well produce a very inaccurate piece of work; but compel her to labour when free from all impediment: she will then--I am convinced of it beforehand--apply her talents without constraint and show herself an adept in the building of graceful nests. As laying-time approaches, towards the middle of August, I instal half-a- dozen Labyrinth Spiders in large wire-gauze cages, each standing in an earthen pan filled with sand. A sprig of thyme, planted in the centre, will furnish supports for the structure, together with the trellis-work of the top and sides. There is no other furniture, no dead leaves, which would spoil the shape of the nest if the mother were minded to employ them as a covering. By way of provision, Locusts, every day. They are readily accepted, provided they be tender and not too large. The experiment works perfectly. August is hardly over before I am in possession of six nests, magnificent in shape and of a dazzling whiteness. The latitude of the workshop has enabled the spinstress to follow the inspiration of her instinct without serious obstacles; and the result is a masterpiece of symmetry and elegance, if we allow for a few angularities demanded by the suspension-points.
