Then swiftly there dashed upon them a group of great fishes with long saws sticking out in front of their noses, armed with sharp, hooked teeth, all set in a row.

They were larger than the swordfishes and seemed more fierce and bold.

But the mermaids and Trot and Cap'n Bill quietly awaited their attack, and instead of tearing them with their saws as they expected to do, the fishes were unable to touch them at all.

They tried every possible way to get at their proposed victims, but the Magic Circle was all powerful and turned aside the ugly saws; so our friends were not disturbed at all.

Seeing this, the sawfishes soon abandoned the attempt and with growls and roars of disappointment swam away and were quickly out of sight.
Trot had been a wee bit frightened during the attack, but now she laughed gleefully and told the queen that it seemed very nice to be protected by fairy powers.
