Yesterday I spotted a few more frogs. I counted 19 of them. Another count today came to 23! I'm pretty sure there were a few more lurking beneath the surface too.
Where all the frogs have come from I don't know. But they're having a whale of a time. I hope the predicted frosts don't do for the spawn over the next week or so.

The fishing line over the pond was put there to keep ducks off. A pair of mallards landed on the pond late last year and ate most of the snails. I've seen one or two snails since, so I'm hoping they'll breed as rapidly as my initial stock did and recolonise the pond this summer.
