In my enclosure, which I have stocked carefully with the most famous breeds, I have six different species under observation, all of a useful size, all first-class spinners. Their names are the Banded Epeira (_Epeira fasciata_, WALCK.), the Silky Epeira (_E. sericea_, WALCK.), the Angular Epeira (_E. angulata_, WALCK.), the Pale-tinted Epeira (_E. pallida_, OLIV.), the Diadem Epeira, or Cross Spider (_E. diadema_, CLERK.), and the Crater Epeira (_E. cratera_, WALCK.). I am able, at the proper hours, all through the fine season, to question them, to watch them at work, now this one, anon that, according to the chances of the day. What I did not see very plainly yesterday I can see the next day, under better conditions, and on any of the following days, until the phenomenon under observation is revealed in all clearness. Let us go every evening, step by step, from one border of tall rosemaries to the next. Should things move too slowly, we will sit down at the foot of the shrubs, opposite the rope-yard, where the light falls favourably, and watch with unwearying attention. Each trip will be good for a fact that fills some gap in the ideas already gathered. To appoint one's self, in this way, an inspector of Spiders' webs, for many years in succession and for long seasons, means joining a not overcrowded profession, I admit. Heaven knows, it does not enable one to put money by! No matter: the meditative mind returns from that school fully satisfied. To describe the separate progress of the work in the case of each of the six Epeirae mentioned would be a useless repetition: all six employ the same methods and weave similar webs, save for certain details that shall be set forth later. I will, therefore, sum up in the aggregate the particulars supplied by one or other of them. My subjects, in the first instance, are young and boast but a slight corporation, very far removed from what it will be in the late autumn. The belly, the wallet containing the rope-works, hardly exceeds a peppercorn in bulk. This slenderness on the part of the spinstresses must not prejudice us against their work: there is no parity between their skill and their years. The adult Spiders, with their disgraceful paunches, can do no better. Moreover, the beginners have one very precious advantage for the observer: they work by day, work even in the sun, whereas the old ones weave only at night, at unseasonable hours. The first show us the secrets of their looms without much difficulty; the others conceal them from us. Work starts in July, a couple of hours before sunset.
