Hiya LS,
I got the text from a paper book, but was going to suggest you have a look at the Gutenberg project, as they have much of Scott's work online. I went for a quick search, and lo and behold, they also have a e-version of the book I got the poem from.

Btw, if anyone tries to tell you that the poem refers to a small mound next to Hermitage castle, apparently they're wrong. It's also called 'The Cout's grave', (interchangeable 'u' and 'w') and whilst it might actually be the grave of the fella known as the Cowt, it's not the mound at Deadwater, which is next to the old chapel.
