It's online at youtube in 15 parts. I can't imagine why I can't find this in one piece somewhere. It must be in the public domain. [moderating a spam comment led me back to this post, and as I did a quick google search I found the film online at youtube and am adding it below.]
Variety says, "D.W. has taken a simple, elemental, old-fashioned, bucolic melodrama and milked it for 12 reels of absorbing entertainment." Eyewitness History has information on the making of the film. Bright Lights has an article that says,
Way Down East is a supreme example of a film's "opening up" of a play, accomplished with uncommonly fluid results in its use of open air, rural settings. None of the outdoor work appears gratuitous or forced, as is so often the result, even today, of reimagining a play outside its proscenium-defined settings. What's more, in Griffith's bucolic epic the landscape, and how the director contextualizes the characters within it, becomes part and parcel of the drama itself. Schickel argues powerfully that the rural settings in Way Down East constitute an emotional landscape that completes "a dramatic and moral arc."
