How to get Google to drop redirected site?

When will a 301 "kick in"

[girish]

My two domains "widget-museum.org" and a related domain "big-widgets.com" are both indexed in Google. Until a month ago they each had unique, non-overlapping content. Last month I copied the entire "widget-museum" site and placed it in a folder within the "big-widgets.com" site called "big-widgets.com/widget-museum/". Simultaneously, I set up a 301 from "widget-museum.org" to this new folder as follows:

RewriteEngine On RewriteRule (.*)$ http://www.big-widgets.com/widget-museum/$1 [R=301,NC]

Now when I search Google for the phrase "widget museum" both domains are ranking in positions 1 and 2, respectively. Previously, the "big-widgets.com" site never ranked for this phrase as there was no "museum" content on it before last month.

I am concerned that Google may incorrectly think I am spamming the index with dup content even though there is no dup content online, it's all in Google's caches. How do I get Google to drop any references to the 301'd site? I want to avoid any spam and dup content problems for the "big-widgets.com" site. Is there any way to alert Google about this issue? Where do I tell Google to drop any references to the original "widget museum" site?
