. Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . de fromheavy gauge copper spun true to a para-bolic curve, heavy silver plated and finelypolished. The electrical connections areautomatically made by blade contacts whenthe reflector and slide are in place. It isnot necessary to disconnect wires whenremoving the reflector from the case. In the matter of illuminating power, a250-watt lamp properly focussed in thestandard reflector under normal conditionslights the track suflicient for all headlight-ing purposes for distances of from 1,000to 1,500 feet. A 60 or 100-watt lamp, ineither the 14-in. or 18-in. reflector, is am-ple to meet switching locomotive serviceconditions. Regarding the proper installation, the his terse instructions are of real value toall who are desirous of obtaining the bestresults from the use of the electric head-light. Mr. McGinnis states that a leadingscientific magazine recently published, asa news item, the information that a largerailroad had just purchased SOO electricheadlight equipments. It further stated. TYPE K TLRBINE—INTERIOR. turbo-generator should be located on thetop of the boiler forward of the whistledome, but as near as possible to the sourceof steam supply. If it should be necessaryto locate the turbo-generator back of thewhistle or safety valves, a protector plateshould be provided for protecting theturbo-generator against escaping steamfrom the safety valves and whistle. Inattaching the turbo-generator to the boilerfi-in. studs are used in fastening the ap-pliance. Care should be taken to see thatthe dynamo door and turbine cover arenot fouled by whistle rods and pipes. Dia-grams for the usual methods of wiringwill be furnished by the manufacturers;in special cases, blue prints will be fur-nished. A switch is furnished for turnini?off the headlight and should be placed onthe right side of the cab, convenient to theengineer. In regard to the maintenance o
