IMO a good field master knows the country and educates informs the field about their position (we’re in the Cabin Field, heading north) as well as the hounds and what they’re doing (they’re on a line moving west, so we’re going to cut across this trail to stay up) and the quarry. They somewhat put on a show - especially if we have guests out. They should reinforce etiquette as necessary, but not be a stick in the mud either.
They should be attuned to what the field is experiencing and I agree that if the field is a large, someone should be planted at the back to keep an eye on things.
FM’s should be bold, confident riders but it’s not a total dictatorship either. We have one 1st FM who once missed a cut through, refused to turn around and go back (despite many tenured riders urging him to) and ran us around unnecessarily, throwing us completely off the hounds, and exhausting the horses because his ego wouldn’t step aside for common sense. He’s bold and confident and a consummate horseman though, just doesn’t always collaborate with the field.
We have another 1st FM who doesn’t know the country (and needs a member to help her), is a bit timid about some of the jumps, has no intuition about the hounds and then proceeds to give everyone a riding lesson “eyes up and heels down over the coop everyone” at every single jump. These coops are smaller than 3’ and we can all ride circles around her. She’s in the position because of politics and not ability. We don’t remotely worship her as Hunter’s Rest suggests.
Our 2nd FM is a freaking wildlife wizard. She knows the country intimately, has incredible intuition and instincts, and really can anticipate where the hounds will go. When I ride with her, I view every single time. We often joke that she can conjure up just about anything. Same for our 3rd FM. She’s tenured and a pleasure to ride with. You always come away smarter for riding with those two. We all worship these two for sure.
