Jansen asks where mica comes from, saying he is interested in it because he and his sister fell to wondering about it while watching the tinsmith put up their coal-stove for the winter. Mica comes chiefly from North Carolina, and is found there in all sorts of blocks of various thicknesses and shapes, which can be split and resplit almost without limit, until it becomes the transparent pane of commerce. The material is imbedded or scattered through the feldspar with which the surrounding mountains are covered. The veins are found between walls of slate. It is blasted from the surrounding rock by means of dynamite, and is freed from all impure matter by miners with chisel and pick. From the mines it is taken directly to the shops, where it is split into thin sheets and trimmed into regular forms, which are then ready for the market, the price varying according to the size of the sheets. The average size will fit an ordinary parlor heater. In rare instances, sheets as large as twenty-four by eighteen inches are found; but there is seldom or never a demand for mica of this size, so the sheets have to be cut down. A. W. A.: Fish are sensitive about the nose. They are also able to feel a shock in adjacent water. If a fish be buried in sand till only his tail be left exposed, a slight tap on any part of the tail will excite the fish and cause it to free itself, or attempt to do so. Salmon have been known to wear their snouts to the bone and their tails entirely away at digging in the sand and stones for a nest in which to spawn. This and other facts go to prove that fish, in spite of their sensitiveness about the nose and tail, do not feel pain, as from a hook in their gills or even in their stomachs. Fish that have been torn by a hook will often grab for a second bait, showing an inclination to feed, which they would scarcely do if suffering acute pain.
