We think that there may be just a little tooth envy going on here, but the two terriers wouldn't be anywhere near it if the tractor and saw-bed were running.
The farmer is about to start sawing up this pile of seasoned logs into manageable lengths for splitting and he won't stop until he has a winter's supply safely stored under cover in one of his disused buildings. You don't want to be sawing and splitting wood in the pouring rain or snow; fill the log basket, light it and be warm.
In the last couple of evenings we've detected the aroma of burning fruit wood so it won't be long before the executive order is given to light the wood-burner.
Once the fire is up and running the two terriers will know what the saw was for, not just to impress them with its teeth but to help keep their belly's warm, that's what.
