Bill,
The yardages are from a "Billy" Bunker article summing up the success of the first year at Cobbs. The print is a bit tough to read so it's possible that the 2nd hole number is wrong. Do the numbers I listed add up to 6122?
Bill/Tommy,
In the same article, it discusses the popularity of the course among major league baseball players;
"Every major league baseball team that comes to Philadelphia has several, and in some cases, a dozen golfers among its members. Any morning during the stay of these teams in town, these players may be seen at the course."
Kyle,
A bit more on Aronimink from Billy Bunker in 1917;
"The second oldest golf club in the city was the old Aronimink golf club, which for years maintained a nine-hole golf course in West PHiladelphia. Their first golf was played over the old Belmont Cricket club course and either six or seven holes were used and the holes were made of tomato cans."
"Aronimink has had many architects, including George Klauder, Cecil Calvert, A.W. Tillinghast, Harry Vardon, and Edward Ray. The latest changes were made by Donald Ross. Ross has made all of the recent improvements to the PHiladelphia Cricket Club course. He is also the architect of the new Gulph Mills club."
