Sven,
Thanks for weighing in and for that additional information. I keep trying to picture today's 16th (9th of the "Long Nine") at 250, and then 275 yards and I'm thinking it was a pretty cool short four. I'm also trying to envision #11 as a par three but I'm guessing that there was probably a much foreshortened green originally on #10.
By the way, the term "Long Nine" doesn't come from me, but instead comes from Edward Weeks club history book, and he relies on a number of sources that include the club's "Run Books" (assuming those are minutes, or periodic accounts of activity), the Herbert Leeds scrapbook (which has sadly gone missing), and other member and independent accounts.
Other hole yardages changed considerably between the two courses, with today's 2nd hole being extended about 50 yards and the famous 9th par three going from 100 to 141 yards.
And while it may be easier for us to just consider the two courses we know the most about, as you suggest, the facts indicate that there was a nine hole course prior to the Long Nine, which is reported by Weeks and also by John P. May who wrote that the original nine (he also stated that it was laid out by Appleton, Merrill, and Gardner) was "only 2,050 yards", and ended at today's 13th green. It was also reported that some of that course was on the low land not yet purchased owned by Dr. Hopkins and today's holes 14, 15, and 16 (holes 7, 8, and 9 of the "Long Nine") were not part of the land used for the original course.
That fact is proven by the 1895 Scribner's article I posted yesterday that stated the finishing hole was the Pond Hole (a shortened version of today's 13th with a green well left of today's ladies tees in a wooded area that used to have a pond, since overgrown, that needed to be carried or averted to the right on the tee shot).
While it's fascinating to compare the Long Nine and the first (and subsequent) eighteen hole iterations, I'd still love to find more about the original course, no matter who designed it. I'm wondering if there isn't a map in the Essex County newspaper archives.
