The violent beginning of the land rush...
What a scene! It's amazing what dangerous things stunt men used to go through. I wonder how long the preparation/planning took... Unless they just did it. Something common in older movies that I hate to see -- and I believe is present here -- is people falling along with their horse! How easily can't such a thing go terribly wrong? A slight miscalculation and you got a goddang horse on your face...
Also, the guy getting run over was a pretty shocking sight even today. I'm surprised ye audience of olde paid to see this kind of thing.
