This paper explores the relationship between private and common property. It starts with the state of nature, works its way through Roman law, and finishes with a discussion of the application of these principles in a modern context. It explains how the intensification of property use often leads to the need for a public trust doctrine for common pool assets, and explains why long and skinny assets have single dedicated uses, chiefly for communication and transportation which enable them to link together productive property sites used for residence, manufacture, and farming. These long and skinny assets have a large perimeter relative to area, which makes them difficult to defend on the one side, and often exposes them to multiple legal regimes with inconsistent commands. It deals with such specific issues as the distinction between alluvion and avulsion, and offers a detailed analysis of the difficulty of permitting oil and gas pipelines in the United States.1

产权：又长又瘦

本文探讨了私有财产与公共财产之间的关系。它从自然状态开始，贯穿罗马法，最后讨论了这些原则在现代语境中的应用。它解释了财产使用的集约化如何经常导致对公共池资产的公共信托原则的需求，并解释了为什么长而瘦的资产具有单一的专用用途，主要用于通信和运输，这使它们能够将使用的生产性财产站点连接在一起用于居住、制造和农业。这些又长又瘦的资产相对于面积而言具有较大的周长，这使得它们一方面难以防御，并且经常使它们暴露于具有不一致命令的多种法律制度。
