No. 3, in March. It contains a general description of the stone, 

 which is quarried for purposes of construction, following 

 the geographical distribution and the geological positions of 

 the formations and outcrosses, and an account, in detail, of 

 the several quarry districts and quarries. The location, extent, 

 ownership, and statistics of the quarries are given, and the 

 markets, prices, uses and references to examples in construc- 

 tion of the stone, so far as they could be ascertained. The 

 wide-spread and steady demand for this Bulletin, notwithstand- 

 ing its distribution to all quarry owners and others interested 

 in constructive materials in the State, is a proof of the service it 

 is rendering our architects, builders, quarry men and people 

 generally. And it shows the need of similar publications upon 

 all the natural products of the State, which are of economic 

 importance. The dissemination of information upon their occur- 

 rence, nature and uses, is one of the most important aims of a 

 State Museum. Bulletin No. 3 contains VI and 152 pp. 



The scheme for the publication of bulletins on economic sub- 

 jects as announced in the preface of No. 3, proposes a second 

 Bulletin upon the building stone of the State. It is to be devoted 

 to a comparative study and to the extent and value of the use of 

 stone in construction in our cities. A large part of the data relat- 

 ing to stone construction has been obtained. As soon as the 

 necessary analyses and tests can be made the report thereon will 

 be prepared for publication. 



A reconnoissance of the iron ore districts has been made during 

 the past season and notes of the mines and their working, with 

 their statistics, their output and markets have been collected for 

 a bulletin or preliminary report on the iron ores of the State. It 

 can be made ready for the printer early in 1889. According to the 

 present plan it will be followed by a second bulletin giving full 

 descriptions of the mines and of the occurrence of iron ore in the 

 State. The labor of collecting the material for this latter bulletin 

 will probable cover the whole field season of the coming year. 



The rearrangement of the collection of minerals suggested 

 the publication of some notes on its more important features. 

 Mr. Frank L. Nason, instructor in the Troy Polytechnic Institute, 

 was employed to prepare an account of three of the more important 

 suites of minerals. His notes thereon, illustrated by one plate of 

 figures, have been printed as Bulletin No. 4. It describes the occur-
