Fighting their way through the bush, Dobbs passes through a section where the branches have been cut by Howard in front. Then around 10 seconds later the shot of Howard actually cutting through that section is shown.
As Dobbs mutters to himself, Curtin walks between Dobbs and the water race. When he gets to Howard and the water tank at the top of the race, Curtin comes in from the other side of the water race, despite there being no crossing point between Dobbs and the tank.
As Dobbs is looking around trying to find Curtin's body so that he may bury it, he runs into some bushes. As the camera pans to follow him you can easily see where the set ends. A clear space with a light and some sort of water truck is plainly visible
During the gunfight with the bandits, Howard refers to the newcomer as Cody. But at the end of the gunfight, he asks "Wonder who he is?" and uses the newcomer's wallet to identify him as James Cody. However, Cody gives his name to Curtin at the General Store. Curtin briefed the boys when he got back. Howard wondering who he is really means Howard wanting to know more about Cody.
Curtin reads Cody's letter out of sequence. He starts on the front page, then opens to the inside pages. He glances momentarily at page #2 on the left, but immediately starts to read page #3 on the right. He then reads page #2 before turning to the back page.
