766 Tlie Architectural Review and American Builders' Journal. [June, heat equal to coal gas for all ordinary purposes for which the Bimsen bui*ner is used. " The gas does not fall, but rises. " This is the only portable machine we know of making a gas that will not condense. Other machines do not make gas, but simply use the vapor of gasoline, which in an ordinary house using twelve or thirteen burners will sometimes con- dense in a single evening two quarts, and unless the pipes are so arranged that this can return to the drip pan it must remain in the pipes. The prices of these machines vary from $150, upwards. They can be seen at the Agents', Gregory & Stewart, 447 N. Broad street, in this city. A SUCCESSFUL BRICK MACHINE. WE have once drawn attention to the sterling merits of a new and improved brick making machine which has since met with uncommon, but not unmerited, success, and which is most justly entitled the Champion of the West. From the satisfactory accounts we have received of the correctness of our judgment in its favor, we are in- duced to repeat our admiration of its efficacy and economy. It does the mixing and grinding of the clay in the most thorough manner possible. It tempers it, moulds the brick and presses it, all with the one-horse power. Ten bricks at one revolution, or from twenty-five to forty per minute, are moulded by this machine, and in such an excellent manner as to be highly desirable in building. So strongly is this Champion constructed that it costs little or nothing for repairs. We would wish to see its merits fully understood and appreciated, and we refer all interested parties to the man- ufacturer, J. L. Hanna, Franklin, Pennsylvania. A New Paint. — At a recent meeting of the French Academy, M. Sace called attention to the fact that tungstate of baryta forms an excellent white paint, which has as good a tone and depth as white lead, and has the advantage above this of not getting blackened on expo- sure to the atmosphere. Zinc white, which was tried as a substitute for white lead has failed, he said, through wanting body. M. Elie de Beaumont remarked that if this statement was confirmed, it would be of great importance ; for there is no need to employ special mining operations for tungsten, as this metal is commonly found in company with tin. Philanthropic. — The drinking foun- tain noticed in our preceding number, is one of several being erected by an Association instituted for that most laudable purpose in this city. Here truly is one of the palpable points of o-onuine Christianity.
