My dear Holmes, you must have eyes at the back of your head!
"To James Mortimer, M.R.C.S., from his friends of the C.C.H.," suggests an elderly doctor who was awarded the object after years of faithful service.
Watson then goes on with the conclusions of the cane, and says the "C.C.H. is probably the mark of "the something hunt," a local group to whom Mortimer provided some service. "
Well done, Watson, well done!

C.C.H actually means Charing Cross Hospital
The cane was probably presented on the occasion of the man's retirement from the hospital, and only a young man would have retired from a successful city practice to move to a rural one.
Holmes playfully announces, given the appearance of master and dog at their front door.
The man must possess a small spaniel, given the bite marks on the cane!
Hello! I am Dr.Mortimer
Mortimer arrives, introduces himself, and talks to the embarrassed Watson. An ardent phrenologist, Mortimer admires Holmes' skull and announces his desire to consult with "the second highest expert in Europe," a moniker which Holmes disputes.
