It's very clear that the seed merchants were extremely influential in the early days of the golf industry back at the beginning of the 20th century.
We know that Colt became a paid consultant to Suttons extremely early in his career, and thanks to Tony Muldoon, we have some quite good information on that relationship.
However, when he first came to the US in 1911, it seems clear that he was introduced to his clients in Toronto and Detroit by Suttons' rivals Carters. We have good evidence that Carters did a lot of business in the US in those early years; their manager Reginald Beale was a regular visitor to the States and wrote a short book on greenkeeping and course construction in about 1916.
So my question to the historians on here is, when did Carters first get established in the US golf business? And what is the most complete list of courses that they worked on that we can find?
