This Hornbook, a revision of the Hemingway Hornbook, is the most comprehensive one-volume work on oil and gas law and taxation available today. For over three decades, Professor Richard Hemingway's prior editions of this seminal work provided guidance to courts, lawyers, commentators, and students. Six distinguished scholars, Professors Anderson, Dzienkowski, Lowe, Peroni, Pierce, and Smith, have joined together to co-author a new version of this classic treatise. As a one-volume treatise, this work covers the substantive law of oil and gas and federal income taxation of oil and gas transactions. The first two chapters examine the mineral interest/estate and related transactions. The third chapter covers trespass and related issues. The fourth chapter covers adverse possession and dormant minerals. Chapters five through eight examine in detail the oil and gas lease. Chapter nine addresses transfers by the lessor and the lessee. Chapters ten through twelve are devoted to oil and gas taxation.
