I recently came across a three page Mackenzie letter on Bayside Links in Queens, NY, that was for sale but had already been sold by the time I found out about it (rats!). Fortunately the seller was kind enough to pass on the scans to me.
The letter is addressed to the greenkeeper at Bayside a fellow by the name of Griffith. He was William H Griffith who was superintending the construction of the course for Wendell Miller and Mackenzie. Griffith came to Bayside from Mount Union, PA where he had been in charge of the Juniata Valley Colony Club.
The sketch that is included on p3 of the letter was also reproduced in "The Life and Work of Dr Alister Mackenzie" on p155, although the text of the letter that explains the sketch was not included.
What is interesting is that Mackenzie wanted the bunkers deepened but in such a way as to allow for lesser players to putt out of certain parts but away from the pin, while the better player could play out direct but over a higher lip. This is the first time I have read anything from Mackenzie describing this philosophy. How it would work in practice with different pin locations is another matter.
Although the letter is not dated, we have a few clues in the letter in that Mac was about to be in Augusta for a few weeks and that Bayside was near completion. We think this dates the letter to July 1931.
The George Meyer referred to was the client, from the Cord Meyer company.
Anyway, I thought it was interesting item to share.
