Now that's fancy! We had to hunt up a limb, about 1.5-2" in diameter, with a few branches coming off at differnt angles. This would be stuck into the pond bottom, out in a little deeper water. There would be enough slack between the stake and the trap to allow the rat to reach the limb... any other limbs or logs that protruded from the water in the area of the set needed to be removed.

When the jaws clamp down, they would always head for deeper water, and right for the limb that you placed earlier. Nine out of ten times, they would circle the limb and become entangled in the branches which would of course..hold them down.

Hopefully, you had the limb shoved into the bottom well enough to hold em' until he ran out of air.

Crude, but poor people had poor ways and made do with what they had. smile

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
