This, I believe, is the first example in which a State Government in our country has erected a museum for the exhibition of its natural resources, its mineral and rock, its plants and animals, living and fossil. And this seems to me the most appropriate spot in the country for placing the first geological hall erected by the Government; for the County of Albany was the district where the first geological survey was undertaken, on this side of the Atlantic, and, perhaps, the world. This was in 1820, and ordered by that eminent philanthropist, Stephen Van Rensselaer, who, three years later, appointed Prof. Eaton to survey, in like manner, the whole region traversed by the Erie Canal. This was the commencement of a work, which, during the last thirty years, has had a wonderful expansion, reaching a large part of the States of the Union, as well as Canada, Nova Scotia, and New Brunswick, and, I might add, several European countries, where the magnificent surveys now in progress did not commence till after the survey of Albany and Rensselaer Counties. How glad are we, therefore, to find on this spot the first Museum of Economical Geology on this side of the Atlantic! Nay, embracing as it does all the department of Natural History, I see in it more than a European Museum of Economical Geology, splendid though they are. I fancy, rather, that I see here the germ of a Cis-Atlantic British Museum, or Garden of Plants. North Carolina was the first State that ordered a geological survey; and I have the pleasure of seeing before me the gentleman who executed it, and in 1824-5 published a report of 140 pages. I refer to Professor Olmstead, who, though he has since won brighter laurels in another department of science, will always be honored as the first commissioned State geologist in our land.
