　　One morning when we had been riding for five hours, we came to a bridge where the railway cross a pond(池塘). For 30 feet there was nothing but the widely-spaced wooden sleepers(枕木) under our wheels, and nothing to stop us falling into the steaming pond below if we overbalanced. Right under the bridge lay the body of a dead cow. I watched Mat as he approached(接近) the bridge and rode straight over, without even slowing down. I stopped.

　　“What’s up?”he cried out from the other side.

　　“I’m not riding over that thing. If I slip, I’ll be in there with that cow.”

　　“There’s nothing to it, I just did it, didn’t I?”

　　“You are stronger and taller. My feet don’t touch the ground. You do it for me!”

　　Mat said strength didn’t come into it and rode off. I knew he would give me at least an hour before coming to help. The sun burned my face, sweat ran off my forehead into my eyes and stuck my shirt to my body. Try myself rather than wait for Mat to help. I rode back to get a good run-up and over I went. Mat was right: All difficulties were in the mind.
