We believe also that Mr. Schmidt was the first, and up tothe present time, perhaps the only one, who has realized inpractical working the employment of steam raised to tem-peratures neighboring 350 degrees to 380 degiees (662 and 716Fahrenheit). It is certain that by these means a great degreeof economy has been obtained, and it is also certain that to Translated for the American Engineer from PortefeulUe Econo-mlque dea Machines. Superheated each square meter of heating surface. The production ofsteam reaches nearly 40 kilograms of steam per square meterof heating surface. It is evident that the gases of combustionmust enter the chimney at a very high temperature. If theseboilers were not surmounted by superheaters they would mak
