A supplement to Ures Dictionary of Arts, Manufactures, and Mines, : containing a clear exposition of their principles and practice. . 82 83 --, 84 191 192 BREAD. taking the loaves out of the oven. The general directions given by M. RoUand for each ofthese operations are as follows :— In order to obtain a proper heat, and one that may be Qasily managed, it is necessary tocharge the furnace moderately and often, and to keep it in a uniform state. When the fire is kindled, tlie door should be kept perfectly closed, in order to compelthe current of air necessary to the combustion to pass through the grate, and thence throughthe flues under and the dome over the oven. If, on the contrary, the furnace door wereleft ajar, the cold air from without would rapidly pass over the coals, without becoming 85. properly heated, and, passing in that condition into the flues, would fail in raising it to theproper temperature. In order that the flame and heated-products of the combustion maypass through all the flues, it is, of course, necessary to keep them clear by introducing intothem once a month a brush made of wire, or whalebone, or those which are now generallyused for sweeping the tubes of marine tubular boilers, and the best of which are thosepatented and manufactured by Messrs. Moriarty, of Greenwich, or How, of London. Thevertical flues which are built in the masonry are cleared from without or from the pit, ac-cording to the nature of the plan adopted in building the oven. These flues need not becleaned more often than about once in three months.
