Before the day's work was ended, however, little Jem again had a glimpse of the prize which had escaped him on the previous occasion. He instantly darted, hands and head foremost, into the mass of cinders and rubbish, and brought up a black mass of half-burnt parchment, entwined with vegetable refuse, from which he speedily disengaged an oval frame of gold, containing a miniature, still protected by its glass, but half covered with mildew from the damp. He was in ecstasies at the prize. Even the white cat-skins paled before it. In all probability some of the men would have taken it from, him "to try and find the owner," but for the presence and interference of his friends Peg Dotting and old Doubleyear, whose great age, even among the present company, gave them a certain position of respect and consideration. So all the rest now went their way, leaving the three to examine and speculate on the prize. The dust-heaps are a wonderful compound of things. A banker's check for a considerable sum was found in one of them. It was on Herries and Farquhar, in 1847. But bankers' checks, or gold and silver articles, are the least valuable of their ingredients. Among other things, a variety of useful chemicals are extracted. Their chief value, however, is for the making of bricks. The fine cinder-dust and ashes are used in the clay of the bricks, both for the red and gray stacks. Ashes are also used as fuel between the layers of the clump of bricks, which could not be burned in that position without them. The ashes burn away, and keep the bricks open. Enormous quantities are used. In the brick-fields at Uxbridge, near the Drayton Station, one of the brickmakers alone will frequently contract for fifteen or sixteen thousand chaldron of this cinder-dust, in one order. Fine coke or coke-dust, affects the market at times as a rival; but fine coal, or coal-dust, never, because it would spoil the bricks.
