Kelton, who grew up on a ranch in Crane County and worked as a farm and ranch writer and editor, says, "To whatever extent technology has allowed, [ranchers and farmers] have tried to influence their environment to their benefit. Some of the results have been favorable. Others have fallen victim to the unwritten law of unintended consequences, trading one set of problems for another." The growing habits and many uses of the ubiquitous mesquite, which flourishes across one-third of Texas. The numerous mineral springs that exist in nearly every Texas county, and their use by Indians, settlers, and commercial spas. Families of Lebanese-Syrian descent and their impact on culture across the state.
