Bill,
Tilly would not have provided a design or have done any substantive work toward one. In the case of your club, whose job he didn't get, he would most likely have done what he did at 5 Farms which he contracted for in 1924.
I chose 5 farms as the example because it is one of the few clubs that have almost all of the Club's and Tilly's correspondence in their files, despite it having been lost at one time. Note what he wrote:
“Gentleman,
“This will confirm the verbal agreement which I made with your committee on Monday, June 9th, 1924. It is agreed that the Baltimore Country Club retains my services to perform the following duties:
[So here we see that the job has been awarded to him. Note in the next paragraph what he HASN't yet done...]
“After a careful examination and analysis of the new property, I agree to lay out two (2) courses, each of eighteen (18) holes. These are to be staked on the ground and after the various points had been located by your surveyor, I am to prepare a completely detailed working plan of the thirty-six (36) holes, showing other vital features, such as Driveways, Parking places for motor cars, Tennis Courts and Practice Grounds for Driving and Putting..."
[So Tilly had yet to make a real design or even a long examination of the property BEFORE he had given both a proposal and plan.]
This was his normal means of contracting for his work. he would make both a strong presentation and also have overcome any political pressures beforehand suually due to his knowing one or more of the decision-makers. It is they who would usually get him invovled. Still, where he didn't personally know any of the parties he would concentrate on the presentation and design the course later. The closest he would come to design work would usually be pointing out certain holes that might be available to build if he got the job.
Rarely did Tilly ever get into a design competition...
