Then I began to think of how hard it was to walk, the water keeping me back; and directly after, as I stepped suddenly in a soft place all mud, which seemed to ooze up between my toes, the water came to my shoulders, and I felt as if I were being lifted from my feet.

"I should like to swim," I said.
"Oh it's easy enough once you get used to it.
