members. The state geologist was allowed to appoint one 

 assistant state geologist, who was required to be a chemist, at an 

 annual salary of $2,000 ; also other subordinate assistants at not 

 more than $1.50 per day. Provision for the appointment by 

 the Board of a state assayer was also made. For the " general

 in March, 1871. The number of the members of the Board was 

 reduced to four, and the allowance for the annual expenses raised
