"You see, I said to myself, "The only difficulty is with the feet: the HEAD is high enough already." Now, first I put my head on the top of the gate--then I stand on my head--then the feet are high enough, you see--then I'm over, you see." "Yes, I suppose you'd be over when that was done," Alice said thoughtfully: "but don't you think it would be rather hard ?" "I haven't tried it yet," the Knight said, gravely: "so I can't tell for certain--but I'm afraid it WOULD be a little hard." He looked so vexed at the idea, that Alice changed the subject hastily.

When I used to wear it, if I fell off the horse, it always touched the ground directly.

So I had a VERY little way to fall, you see--But there WAS the danger of falling INTO it, to be sure.
