How to add large number of pages to a content type? I created a content type "cities", with
Fields: Title, body, location(text field)

I would like to create about 200 pages for this content type. 

I can create manually one by one. It will take a lot of time to do that. Is there faster way I can add the pages by using some bulk load methods?
Use the Devel module, and its devel_generate submodule.

Using this submodule, you can perfectly create 200 nodes (with randomly generated content) of any content type.
