 applications will be given. 



Areas known to have been occupied by actual settlers 

 prior to January 1, 1906, will be examined first, and 

 when such areas are found chiefly valuable for agricul- 

 ture, they will be listed in order that the occupants may 

 make entry under the act. The mere fact that a person 

 has settled upon land will not influence the decision 

 with respect to its agricultural character. Settlers 

 must not expect to include valuable timberland in their 

 entries. Settlement made after January 1, 1906, and

 will be trespass. 



Settlement and entry under the act will be within the 

 jurisdiction of the Secretary of the Interior, who will 

 issue appropriate instructions. (Appendix, p. 175.)

Mining claims within forest reserves may be freely 

 sought for, located, developed, and patented in accord- 

 ance with the mineral land laws and forest reserve reg- 

 ulations. (Appendix, p. 160.) The administration of 

 these laws is under the jurisdiction of the Secretary of 

 the Interior. (Appendix, p. 161.) 



The discovery of a mere trace of mineral is not suf- 

 ficient to make a claim valid, unless both the character 

 of the mineral and the manner of its occurrence are 

 such as to warrant expenditure for development and 

 reasonable expectation of a valuable discovery. (Ap- 

 pendix, p. 192.) 



In entries of placer mining claims by associations, if 

 any subdivision is not mineral and this fact is shown,
