The bowed materials for one hat are divided into two portions, each of which is separately pressed with a light wicker frame; the light mass of fluffy fur, after being pressed with the frame, is covered with a wet cloth, over which is placed a piece of oil-cloth or leather called a "hardening skin," until, by the pressure of the hands backwards and forwards all over the skin, the fibers are brought closer together, the points of contact multiplied, the serrations made to link together, and a slightly coherent fabric formed. These two halves, or "batts," are then formed into a hollow cap by a singular contrivance. One of the "batts," nearly triangular in shape, and measuring about half a yard in each direction, being laid flat, a triangular piece of paper, smaller in size than the batt, is laid upon it, and the edges of the batt, being folded over the paper, meet at the upper surface, and thus form a complete envelope to the paper. The two meeting edges are soon made to combine by gentle pressure and friction, and another "batt" is laid on the other in a similar way, but having the meeting edges on the opposite side of the paper. The double layer, with the enclosed paper, are then folded up in a damp cloth and worked by hand; the workman pressing and bending, rolling and unrolling, until the fibers of the inner layer are incorporated with those of the outer. It is evident that were there not a piece of paper interposed, the whole of the fibers would be worked together into a mass by the opposite sides felting together, but the paper maintains a vacancy within, and when withdrawn at the edge which is to form the opening of the cap, it leaves the felted material in such a form as to constitute, when stretched open, a hollow cone.
