quite a famousengine in Chili, and after pulling freightand passenger trains for many years, wasonly a few years ago assigned to the lessdignified service of switching. The time,however, came when even switching wasmore than the engine could do efficiently,and so she was placed into dignified re-tirement. When the Chilian Governmentwas invited to send exhibits to the Pan-American Exposition, they decided to much as they are to-day, and the enginehas what was known as the Bury barframe, also a Bury hay-stack firebox. Arather striking feature is the old-fashionedpump, operated by cross-head with airchamber and drop valves. Combustion and Meat. BY ANCU.S .SINXLAIR.THIRD PAPER. Metals are melted and vaporized asreadily as water under the action of heat.When a metal or other substance is diffi-cult to melt it is called refractory. Thusfireclay arches are put into furnaces andgraphite crucibles are used in retortswhere steel is melted. These are aboutthe most refractory substances known to

They let the rays from the sun passthrough and return freely into space, butthey do not retain the heat to any greatextent. By elaborate calculations a cele-brated scientist estimated that a decreaseof carbon dioxide in the atmosphere to theextent of from 55 to 67 per cent, would re-duce the average temperature about 40 de-grees Fahr. and would produce a glacialepoch; while increasing the proportion toan amount two or three times the presentadmixture would elevate the average tem-perature about 47 degrees Fahr., whichwould bring a mild climate into the highlatitudes. make the Copiapo a part of their ex-hibit, which otherwise is very full andvery interesting, although most of it isnot of a character that would be interest-ing to railroad men. The principal peculiarity of the engineis that she has six eccentrics, two ofthe
