A Hedgehog curls himself up into a ball and his prickles stick out every which way at once. By this you may know the Hedgehog.'

'I don't like this old lady one little bit,' said Stickly–Prickly, under the shadow of a large leaf. 'I wonder what else she knows?'

'A Tortoise can't curl himself up,' Mother Jaguar went on, ever so many times, graciously waving her tail. 'He only draws his head and legs into his shell. By this you may know the tortoise.'

'I don't like this old lady at all—at all,' said Slow–and–Solid Tortoise. 'Even Painted Jaguar can't forget those directions. It's a great pity that you can't swim, Stickly–Prickly.'

'Don't talk to me,' said Stickly–Prickly. 'Just think how much better it would be if you could curl up. This is a mess! Listen to Painted Jaguar.'

Painted Jaguar was sitting on the banks of the turbid Amazon sucking prickles out of his Paws and saying to himself—

'Can't curl, but can swim—
Slow–Solid, that's him!
Curls up, but can't swim—
Stickly–Prickly, that's him!'

'He'll never forget that this month of Sundays,' said Stickly–Prickly. 'Hold up my chin, Slow–and–Solid. I'm going to try to learn to swim. It may be useful.'

'Excellent!' said Slow–and–Solid; and he held up Stickly–Prickly's chin, while Stickly–Prickly kicked in the waters of the turbid Amazon.

'You'll make a fine swimmer yet,' said Slow–and–Solid. 'Now, if you can unlace my back–plates a little, I'll see what I can do towards curling up. It may be useful.'

Stickly–Prickly helped to unlace Tortoise's back–plates, so that by twisting and straining Slow–and–Solid actually managed to curl up a tiddy wee bit.

'Excellent!' said Stickly–Prickly; 'but I shouldn't do any more just now. It's making you black in the face. Kindly lead me into the water once again and I'll practice that side–stroke which you say is so easy.' And so Stickly–Prickly practiced, and Slow–Solid swam alongside.

'Excellent!' said Slow–and–Solid. 'A little more practice will make you a regular whale. Now, if I may trouble you to unlace my back and front plates two holes more, I'll try that fascinating bend that you say is so easy. Won't Painted Jaguar be surprised!'

'Excellent!' said Stickly–Prickly, all wet from the turbid Amazon. 'I declare, I shouldn't know you from one of my own family. Two holes, I think, you said? A little more expression, please, and don't grunt quite so much, or Painted Jaguar may hear us. When you've finished, I want to try that long dive which you say is so easy. Won't Painted Jaguar be surprised!'

And so Stickly–Prickly dived, and Slow–and–Solid dived alongside.

'Excellent!' said Slow–and–Solid. 'A leetle more attention to holding your breath and you will be able to keep house at the bottom of the turbid Amazon. Now I'll try that exercise of putting my hind legs round my ears which you say is so peculiarly comfortable. Won't Painted Jaguar be surprised!'

'Excellent!' said Stickly–Prickly. 'But it's straining your back–plates a little. They are all overlapping now, instead of lying side by side.'

'Oh, that's the result of exercise,' said Slow–and–Solid. 'I've noticed that your prickles seem to be melting into one another, and that you're growing to look rather more like a pinecone, and less like a chestnut–burr, than you used to.'

'Am I?' said Stickly–Prickly. 'That comes from my soaking in the water.
