Tom, What you say makes sense. Colt did not have much volume in North America. WW1 saw to that. Colt did come to North America with the message that copying even the best features and holes of other courses, i.e. template holes, was wrongheaded. It can't have been all wrong because that design philosophy became the underpinning for some of the greatest courses ever built.
When Harry Colt arrived in Chicago in April of 1913, the April issue of "Golf" had just been published. The Editor of "Golf" was Max Behr, who later authored his famous essays laying out his ideas on "permanent architecture" and "hiding the architect's hand." It was the rival magazine to Walter Travis' American Golfer.
Everybody in the golf world in North America - architects, intellectuals, constructors, golf club board members, and golfers - read these two magazines from cover to cover. Behr was an excellent golfer who had lost twice in the finals of the New Jersey Amateur in 1907 and 1908 to Jerry Travers. It seems likely that Max Behr leaned towards Philadelphia and Walter Travis towards Long Island. After the Amateur Championship in 1904, Travis was not enamored of the British and, as mentioned in an earlier post, he was aligned with Ross. Is it possible that Colt was forced on Ross, who had previously visited Old Elm (and Glen View Club) in February 1913, and on Crump by the persuasion of his friends? Perhaps, Colt hoped Ross or even Crump might be a good partner and collaborator in North America, but it was not to be. Too bad he didn't find Stanley Thompson when he was in Canada.
In his April 1913 issue, Behr chose for his long lead article, "Golf Architecture" by the Englishman Harry Colt. The second installment appears as the lead article in the May 1913 issue. The timing of the two articles coincides exactly with the dates of Colt's groundbreaking North American journey which started in April at Old Elm in Chicago and ended in May at Pine Valley in New Jersey.
During Colt's time in North America in 1913, his ideas about golf course architecture would have been on everyone's mind. Max Behr, who went to Lawrencevile in New Jersey, would have known everybody in the Philadelphia and New Jersey golf world. No wonder Colt found his way to Pine Valley.
There is one photo that precedes Colt's April article captioned "Humps and hollows at Mid-Surrey." Colt addresses these humps and hollows immediately; "now we have what is known as the Alpinization of courses, and the few rough mounds which have been made for many years past develop into continuous ranges on every new course. A good idea is worn threadbare in next to no time in golf course construction." It seems to be a distant echo of what you said about frilly bunkers, waste bunkers and island greens.
Colt addresses CB's template philosophy and then distills his own in this lucid and modest statement. "The attempt at reproducing well-known holes with hopelessly different materials is the most futile nonsense of the lot. How often have I seen a piece ground suitable for a good short hole spoilt by a silly attempt at reproducing the 11th hole at St. Andrews (this is the Eden hole). No; I firmly believe that the only means whereby an attractive piece of ground can be turned into a satisfying golf course is to work to the natural features of the site in question. Develop them if necessary, but not too much; and if there are many nice features, leave them alone as far as possible, but utilize them to their fullest extent, and eventually there will be a chance of obtaining a course with individual character of an impressive nature."
It seems like the great architects of today, you and Bill and Ben and Gil and others, and Pete, are descendants of Harry Colt more than C.B. MacDonald. To whatever degree the Oxcam design ideas that Colt developed and put into the dirt around the world and for a brief moment in North America were not lost in the fog and disintegration of time, perhaps they returned triumphant to inhabit the Second Golden Age.
