I agree as Merion is a strange course. The book I have on Merion reads the holes as follows:
Hole 1: Damned Sycamore treeon the right of the tee!
Hole 2: I worry about the Out of Bounds line and the deep rough on the left
Hole 3: Miss the green and a recovery shot is impossible
Hole 4: Damned right-to-left slope
Hole 5: Fairway slopes right-to-left also but a good driving hole
Hole 6: Uphill slope to the green with a back left to the front approach
Hole 7: Begins a stretch of holes for possible birdie chances
Hole 8: Fun and good luck driving up to the green
Hole 9: Difficult par 3 on a downhill green, with a nasty water hazard
Hole 10: On the green, a severe right-to-left curve to approach the hole
Hole 11: Miss the fairway and you're in the brook!
Hole 12: Another severe sloped green from back left to front right....any approach that misses left has a mean up-and-down
Hole 13: Probably the smallest green on the course, but I'm able to birdie it pretty regularly
Hole 14: Uphill par 4, and if you miss on the left you are out of bounds
Hole 15: Dangerously close out of bounds hole on the left
Hole 16: Last real shot at birdie before the 17th & 18th
Hole 17: slightly downhill to the green with a pronounced ridge in the front
Hole 18: Downhill pitch and steep right to left...better to be long on the approach than short
