As the webs which Lucy and Eliza spun were several times broken or mutilated during the year, either by accident or the gardener, we had plenty of chances for seeing how they proceeded in making them. The lines were in both cases stretched between a white rose-bush that climbed up one side of the window, and a purple clematis that occupied and draped the opposite mullion. But Lucy and Eliza didn't live in the webs--those were only their snares or traps for prey; each of them had in addition a private home or apartment of her own under shelter of a rose-leaf at some distance from the treacherous geometrical structure. The house itself consisted merely of a silken cell, built out from the rose-leaf, and connected with the snare by a single stout cord of very solid construction. On this cord the spider kept one foot--I had almost said one hand--constantly fixed. She poised it lightly by her claws, and whenever an insect got entangled in the web, a subtle electric message, so to speak, seemed to run along the line to the ever-watchful carnivore. In one short second Lucy or Eliza, as the case might be, had darted out upon her quarry, and was tackling it might main, according to the particular way its size and strength rendered then and there advisable. The method of procedure, which I shall describe more fully by-and-by, differed considerably from case to case, as these very large and strong spiders have sometimes to deal with mere tiny midges, and sometimes with extremely big and dangerous creatures, like bumble-bees, wasps, and even hornets.
In building their webs, as in many other small points, Lucy and Eliza showed from the first no inconsiderable personal differences. Lucy began hers by spinning a long line from her spinnerets, and letting the wind carry it wherever it would; while Eliza, more architectural in character, preferred to take her lines personally from point to point, and see herself to their proper fastening. In either case, however, the first thing done was to stretch some eight or ten stout threads from place to place on the outside of the future web, to act as _points d'appuy_ for the remainder of the structure. To these outer threads, which the spiders strengthened so as to bear a considerable strain by doubling and trebling them, other thinner single threads were then carried radially at irregular distances, like the spokes of a wheel, from a point in the centre, where they were all made fast and connected together. As soon as this radiating framework or scaffolding was finished, like the woof on a loom, the industrious craftswoman started at the middle, and began the task of putting in the cross-pieces or weft which were to complete and bind together the circular pattern. These she wove round and round in a continuous spiral, setting out at the centre, and keeping on in ever-widening circlets, till she arrived at last at the exterior or foundation threads. How she fastened these cross-pieces to the ray-lines I could never quite make out, though I often followed the work closely from inside through the pane of glass with a platyscopic lens; for, strange to say, the spiders were not in the least disturbed by being watched at their work, and never took the slightest notice of anything that went on at the other side of the window. My impression is, however, that she gummed them together, letting them harden into one as they dried; for the thread itself is always semi-liquid when first exuded.
