122 CLASSIFICATION OF THE PUBLIC LANDS. 



Order of Withdrawal. 



Naval petroleum reserve No. 1. 



It is hereby ordered that all lands included in the following list and hereto- 

 fore forming a part of petroleum reserve No. 2, California No. 1, withdrawn on 

 July 2, 1910, from settlement, location, sale, or entry, and reserved for classi- 

 fication and in aid of legislation under the authority of the act of Congress 

 entitled "An act to authorize the President of the United States to make 

 withdrawals of public lands in certain cases" (36 Stat, 847), shall hereafter, 

 subject to valid existing rights, constitute naval petroleum reserve No. 1, and 

 shall be held for the exclusive use or benefit of the United States Navy until 

 this order is revoked by the President or by act of Congress. To this end and 

 for this public purpose the order of July 2, 1910, is modified and the withdrawal 

 of that date is continued and extended in so far as it affects these lands.

The preliminary withdrawals are made as a first step in classi- 

 fication and are based on recommendations of Survey geologists or 

 of field agents of the General Land Office. A few such withdrawals 

 have been based on petitions filed by residents of the community in 

 which the occurrence of oil is suspected. The purpose of the with- 

 drawals is primarily to withhold the lands from disposition pend- 

 ing their examination and classification. Because of the lack of 

 definite geologic data most of the preliminary withdrawals of neces- 

 sity embrace areas larger than those ultimately found to be valuable. 



As soon as practicable after preliminary withdrawal the lands are 

 examined geologically, and from the data, obtained in this examina- 

 tion, presented and considered as already described, decisions as to 

 the probable productive and nonproductive portions of the area are 

 made. The areas classified as nonoil land are promptly restored and 

 become subject to entry and disposition as if no withdrawal had been 

 made. 



The following order illustrates the form in which such restorations 

 are made :

Sir: Field investigation by the Geological Survey indicates that the lands 

 listed below do not contain deposits of oil or gas. The following order of 

 restoration, which involves 133,626 acres, is therefore recommended for submis- 

 sion to the President for appropriate action. A small part of these lands is
