Editorial Notes

Ownership of Tide Lands

The following syllabus and abstracts of decision in the Superior Court of California by Judge Walter Bordwell, Los Angeles, Cal., are of wide interest to all officers and assistants engaged on river and harbor work. It contains over twenty thousand words and represents a year's hard work and study by one of the ablest judges in California. Two copies are now on file in the Engineer School Library, and it is proposed to obtain several more, all of which will be available to loan to officers desiring to study the full decision.

There are three fundamental truths brought out in the decision which are believed worthy of particular attention.

First. That certain powers and rights are inherent in the sovereignty of a State, and can not be taken away or abridged without impairing that sovereignty. Instance the right of a State to control and use the harbors and waterways within its borders and to have free access thereto.

Second. That the people of a State have certain natural rights which the State itself may not deny them-as the right to use the tide lands of the State for purposes of navigation.

Third. That a deed in fee simple or a grant, or even a lease which impairs a natural right of the public, such as the free use of harbors and waterways and access thereto, is void.

In the specific case decided by Judge Bordwell, the defendants claimed certain tide lands in San Pedro (Los Angeles) Harbor, Cal., by virtue of State patents granted through a perversion of California State laws authorizing the sale and reclamation of swamp and overflowed lands. These California State laws were based on a United States law passed on the 28th of September, 1850, and commonly known as the Arkansas Swamp-land Grant, by which the United States Government granted to Arkansas, and each of the other states then in the Union, all the swamp and over
