Grabbing from a particular index onwards

From the Scraperwiki mailing list:
    You can open .xls-es then navigate around them w/ xlrd

 
I did one here: 
https://scraperwiki.com/scrapers/testing_with_the_intro_tutorial_atlanta_schedule/
 
I had like, one zillion spreadsheets all formatted exactly the same and I 
needed, like, rows[40:] out of all of them. So this scraper opened each 
one, scraped out all the rows from 40 till the end, closed the xls, went 
back to the main page and iterated down to the next xls to open.
