Lighting of Baseball and Football Fields Enables Many More Fans toSeeGames Fenway Park, homeof theBoston Red Sox, hasillumination over entire field eight times brighter than that from an average home reading lamp. Attendance atnight major-league baseball games averages three times the number at day games. Allmajor-league fields butonearenow lighted.

Even an ordinary-size turbine issopowerful that the late CharlesP.Steinmetz, scientist, estimated that it does asmuch work in24 hours as all the slaves intheSouth could perform in 1860. The boilers of a modern steam power plant are as high as an eight- ornine-story building, and the turbines areso large that Ihave stood inside of one from which themoving parts had been removed for repair. This was in the Fisk Station oftheCom monwealth Edison Company, ofChicago, the first all-turbine steam station inAmerica. Although in operation since 1903, itisstill an important sourceof power because oflarge modern units installed from time totime. The visitor to amodern power plant isstruck notonly bytheextreme cleanliness and orderliness oftheplace butalso bythefact that sofew employees arerequired. Pul verized coal ishandled bymachinery, and ittakes only afew employees towatch themeters, charts, and automatic controls. Because asmall plant requires almost asmany operators asalarge one, thesheer necessity foreconomy drives thecompanies tobuild plants whose generating capacity isasgreat aspossible. The Stimulus ofColor When Ivisited theBuzzard Point station ofthePotomac Electric Power Company inWashington, D.C.,about half theinterior had been done over inthenew color dynamics, with greens, reds, blues, and yellows taking theplace oftheoldgloomy dullness ofunpainted heavy machinery. Most operators prefer towork intherepainted sections.
