I went to the circus and loafed around the back side till the watchman went by, and then dived in under the tent. I had my twenty-dollar gold piece and some other money, but I reckoned I better save it, because there ain’t no telling how soon you are going to need it, away from home and amongst strangers that way. You can’t be too careful. I ain’t opposed to spending money on circuses when there ain’t no other way, but there ain’t no use in WASTING it on them.
