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 expenses" of the bureau the sum of $7,500 was allowed annually Under this law Albert D. Hager, previously of the Vermont survey, was appointed state geologist. The law was amended in March, 1871. The number of the members of the Board was reduced to four, and the allowance for the annual expenses raised to $10,000. Mr. Hager held this position until August, 1871, and published one report of progress, twenty-one pages in length, in which he briefly notices the chief building stones and minerals of the state. After Mr. Hager's resignation, Dr. J. C. Norwood was in temporary charge. In November, 1871, Mr. Raphael Pumpelly was appointed state geologist. He resigned from the position in May, 1873.

Up to the time of Mr. Pumpelly's appointment, very little had been made public of the results of the surveys, and the changes of management must necessarily have retarded and weakened the work. Notwithstanding this, however, Governor B. Gratz Brown, in his message of December, 1871, commends the survey warmly to the Legislature, and, as a result, the law was amended in the following March, and the sum of $20,000 was appropriated annually for the salaries and expenses of the Bureau.

Two classes of work were provided for in the Pumpelly survey, i.e., (1) the study of the stratigraphy of the state; (2) the study of the mineral deposits. The stratigraphic work was divided into five departments covering different sections of the state; that of economic geology was divided into three, including a department of iron ores and metallurgy, a department of ores other than iron, and a department of fuels and materials of construction other than iron and wood. Under the Pumpelly management two reports were issued in 1873. The first was an octavo of 323 pages, already referred to as containing twenty
