Annie mentions how Jack smelled a couple of times in the ss. Always, no matter what he was doing or how much he may have stunk, there was a pleasant under-odor that he exhuded. I think she always wanted the reader to know that Jack was desireable, no matter how much physical exertion he may have been doing, or how seldom he may have been able to bathe well. There was something attractive in his personal scent that drew in Ennis, and everyone else who got close enough. I mean, let's face it, being on the road rodeoing and having so little money, Jack couldn't have spent too many nights in a nice motel with good shower facilities. He had to be rank at times. Still, Annie makes it a point to bring up his smell and always concludes her description with something good, like earthiness, or clean air, or fresh hay. This greatly enriches our total picture of Jack. She doesn't mention Ennis's odor, as I recall. That's a mystery.
