Tom, read my book, I even included the map by the original landscape architect, Charles H. Ramsdell. Ross was there in 1912 to do the original nine and came back in 1915 to do another nine, mainly with additional new holes north of the crossing road. Any questions should be directed to the longtime club superintendent, John Steiner, who has direct knowledge of every feature of the original design.
By the way, it was common to have an outside engineer do the full rendition - certainly before Ross got his own staff enginer in Oct. 1920. Rhode Island CC has the same thing on display on its clubhouse - a full design drawing by an engineering firm that relied upon Ross' plans.
