This notebook was kept for the Greenpoint Gasworks when coal gas or "town gas" was produced and piped to customers of the distribution system. Prior to the discovery of natural gas, coal gasification plants such as the Greenpoint gasworks produced gas from coal (or coke as this engineer's notebook confirms).
