They came to an area containing human artifacts. Much of it was from the City itself, Dura gathered, but from ages past; Ito laughed as she pointed to clothes and hats mounted on the walls. Dura smiled politely, not really seeing the joke. There was a model of the City, finely carved of wood and about a mansheight tall. There was even a lamp inside so that the model was filled with light. Dura spent some time peering at this in delight, with Ito pointing out the features of the City. Here was a toy lumber train entering one of the great ports Downside, and here was the Spine leading down into the underMantle; tiny cars carrying model Fishermen descended along the Spine, seeking lodes of precious Corestuff. And the Palace at the very crown of the City — at the farthest Upside of all — was a rich tapestry glowing with life and color.

Further along, there were small cases containing artifacts from outside the City. Ito touched her arm. "Perhaps you'll recognize some of this." There were spears and knives, all carved from wood; she saw nets, ponchos, lengths of rope.

Upfluxer artifacts.

None of them looked as if they had come from the Human Beings themselves. But, said Ito, that wasn't so surprising; there were upfluxer bands all around the fringe of Parz's hinterland, right around the Star's Polar cap. Dura studied the objects, aware of her own knife, her rope still wrapped around her waist. The things she carried wouldn't be out of place inside one of these displays, she realized. With a tinge of bitterness, she wondered if these people would like to pin her and her brother up on the walls, like that poor, dead ray.

Finally, Ito brought her to the Museum's most famous exhibit (she said). They entered a spherical room perhaps a dozen mansheights across. The light here was dim, coming only from a few masked wood-lamps, and it took some time for Dura's eyes to adapt to the darkness.

At first she thought there was nothing here, that the chamber was empty. Then, slowly, as if emerging from mist, an object took shape before her. It was a cloud about a mansheight across, a mesh of some shining substance. Ito encouraged her to move a little closer, to push her face closer to the surface of the mesh. The exhibit was like a tangled-up net, composed of cells perhaps a handsbreadth across. And Dura saw that within the cells of the main mesh there was more detail: sub-meshes, composed of fine cells no wider than a hair-tube. Perhaps, Dura wondered, if she could see well enough she would find still more cells, almost invisibly tiny, within the hair-scale mesh.
