The scratch message always says:
;; This buffer is for notes you don\'t want to save, and for Lisp evaluation.
;; If you want to create a file, visit that file w
For Emacs 23, you can do this:
(setq initial-scratch-message nil)
From the documentation: "Initial message displayed in scratch buffer at startup. If this is nil, no message will be displayed."
You can turn off the initial splash screen with
(setq inhibit-startup-message t)
this appears to also remove the initial message in the scratch buffer.
You can customize this variable 'initial-scratch-message
to be whatever message you want.
(setq initial-scratch-message "")
