and in regard to lime production, cement manufacture, the production 

 of gypsum, salt, bromine, petroleum, and inflammable gas. 



No appropriation was made for the work during the year 1884. 

 The expenses were $8,754.16. By a law previously enacted the sum 

 of $10,000 was placed to the credit of the survey. 



On the issue of this volume it was at once seen that the continu- 

 ance of the work in this field was an object to be desired. Accord- 

 ingly, Governor Hoadley reported that much material still remained 

 in possession of the State geologist, consisting in the discussion of 

 the upper coal measures, cements, limestones, salt, petroleum, and gas 

 wells of the State. It was thought that with six months' further field 

 work sufficient material for another volume would be at hand, since 

 the accidental discovery of gas wells in Wood County and elsewhere 

 indicated that " tlie knowledge of our resources was still far from 

 complete." 



As a result there was enacted a law which required the governor 

 to appoint a geologist Avhose duty it should be to extend and complete 

 the account of economic geology begun in volume 5, treating in par- 

 ticular those portions of the Ohio coal fields not yet reported upon, 

 also salt and bromine, the composition, structure, strength, and 

 durability of the building stones of the State, the production of 

 lime, natural cements, marls, and land plaster, and all other sub- 

 stances produced in the State that come under the head of economic 

 geology; empowered the geologist to employ assistants; fixed the 

 salaries and provided for contingents; required the geologist to enter 

 upon his duties as soon as practicable and fixed one year as the limit 

 for the whole work; appropriated $4,500 for all purposes; and pro- 

 vided that the chapter on inflammable gas should be prepared for 

 publication in advance of the rest of the volume, and that the copy 

 be delivered to the supervisor of public printing by October 1, 1885. 



The followhig is the full text of this act, and its supplement, passed 

 a month later: 



An act to provide for the extension of tlie geological survey of Ohio. 



Section 1. Be it enacted 'by the Qeneral Assembly of the State of Ohio, That 

 the giovernor is hereby required to appoint, by and with the advice and consent 

 of the senate, a competent geologist, whose duty it shall be to extend and 

 complete the account of the economic geology of the State that is begun in 

 volume 5, Geology of Ohio. He shall treat, in particular, of those portions of 

 the Ohio coal fields that have not yet been reported upon; of the production 

 of petroleum and inflammable gas in the State, and also of salt and bromine; 

 the composition, structure, strength, and durability of the various building 

 stones of the State; of the production of lime, natural cements, marls, and land 

 plaster; and of all other substances produced in the State that come under 

 the head of economic geology.
