ther just a very little, so as to fill up the pores as it were, and make a smoother surface. If this were not done, it would fly all to pieces the first time it was put into hot water." "The cut glass is not annealed, then?" "Oh, yes, after it is blown it is; and although the grinding takes off part of the surface, I suppose it fills up the pores at the same time." "Cut glass is more apt to break in hot water than pressed or simply blown glass," remarked Madame. "And is all cut glass blown in the first place?" asked Optima. "No, Miss, a good deal of it is pressed and then ground, either wholly or in part; but this is not so clear or free from waves as the blown. Out here is a man blowing _liqueur_-glasses. Perhaps you would like to see that." The idea of blowing a bubble of glass into so intricate a shape, and timing the process so that the brittle material should harden only when it had reached the desired form, struck Miselle's mind as very incredible; and she followed Cicerone with much curiosity to another furnace, where one man, blow-pipe in hand, was dipping up a small quantity of the liquid glass, and, having blown into it just long enough to make a stout little bubble, laid the pipe across the iron arms of a bench, where sat another operator, who immediately began to roll the pipe up and down the arms of his chair, while with a supple iron instrument, shaped like sugar-tongs with flattened bowls, he laid hold of the bubble, and, while elongating it into a tube, brought the lower extremity first to a point and then to a stem. To the end of this the assistant now touched his pontil, upon whose end he had taken up a little more glass, and this, being twisted in a ring round the foot of the stem, divided from the pontil by a huge pair of scissors, dexterously shaped with the plyers, and finally smoothed with a battledoor, became the foot of the wine-glass. The heated pontil was now applied exactly to the centre of this foot, the top of the glass divided from the blow-pipe by the application of cold iron, and the whole thrust for a few moments into the mouth of the furnace to soften, while the first man laid another pipe with another bubble at the end before the operator upon the bench, who recommenced the same process. The first glass, meantime, rendered once more ductile by heat, was passed to another man upon another bench, who, keeping up all the while the rotatory motion necessary to preserve the f
