Abstract: The Consumers Gas Company is using microfilmed copies of records in the field to assist in locating underground plant. Prior to the use of microfilm, the man in the field was issued a set of Alias Plate drawings (22 X 34) which were kept in a post binder. From these records he could determine the location of the main from property on street line, diameter, material, operating pressure, and cross reference number of the source document from which the information was plotted. If he was unable to locate or stake the main from this information, he would either radio or telephone a locations record clerk for more detailed information.
