Richard the Confused:
C.B. Macdonald's time in the wilderness did not end over here in 1905, it essentially ended according to him as the result of the Columbia Exposition in Chicago in 1893 when some devoted golfers came over here for it and began to interest Chicago (with him) in golf. He consequently built the first eighteen hole golf course in America in 1895 you historical dolt!!
His curious machinations in the first two non-official US Amateurs (according to him) at Newport and St. Andrews a few months later precipitated the founding of the USGA and the US Amateur as an officially sanctioned tournament.
Macdonald was one of a few tapped to write the USGA by-laws and with another man named Laurence Curtis was asked to administer the Rules for the USGA which he did for many years. He was also on the R&A Rules of Golf Committee but one shouldn't say he was dictated to by the R&A in the context of the Rules. The R&A was actually something of an unwilling entity to run golf's rules and what Macdonald was interested in via the Rules was simply creating a unified code and system in America with the R&A. In that vein he did often consult on various Rules questions with some of his friends over there such as Horace Hutchinson and a few others.
The knock on Macdonald as being dictated to by the R&A on the Rules really came from Walter Travis over the infamous Schnectedy Putter thing that lasted a number of years. But had Travis bothered to analyze the position Macdonald took via the Schnectedy Putter thing with the R&A and USGA he would've seen Macdonald actually supported him and his Schnectedy putter.
Perhaps inhaling the stench-like aroma of too many cowpies over there is effecting your thinking ability!
