Nor is the year 1656 memorable in the annals of Albany alone. In that same year your imperial metropolis, then numbering about three hundred inhabitants, was first laid out as a city, by the name of New Amsterdam.[A] In eight years more, New Netherland becomes New York; Fort Orange and its dependent hamlet assumes the name of Albany. A century of various fortune succeeds; the scourge of French and Indian war is rarely absent from the land; every shock of European policy vibrates with electric rapidity across the Atlantic; but the year 1756 finds a population of 300,000 in your growing province. Albany, however, may still be regarded almost as a frontier settlement. Of the twelve counties into which the province was divided a hundred years ago, the county of Albany comprehended all that lay north and west of the city; and the city itself contained but about three hundred and fifty houses. [Footnote A: These historical notices are, for the most part, abridged from Mr. Brodhead's excellent history of New York.] TWO HUNDRED YEARS. One more century; another act in the great drama of empire; another French and Indian War beneath the banners of England; a successful Revolution, of which some of the most momentous events occurred within your limits; a union of States; a Constitution of Federal Government; your population carried to the St. Lawrence and the great Lakes, and their waters poured into the Hudson; your territory covered with a net-work of canals and railroads, filled with life and action, and power, with all the works of peaceful art and prosperous enterprise with all the institutions which constitute and advance the civilization of the age; its population exceeding that of the Union at the date of the Revolution; your own numbers twice as large as those of the largest city of that day, you have met together, my Friends, just two hundred years since the erection of the little church of Beverswyck, to dedicate a noble temple of science and to take a becoming public notice of the establishment of an institution, destined, as we trust, to exert a beneficial influence on the progress of useful knowledge at home and abroad, and through that on the general cause of civilization. SCIENTIFIC PROGRESS. You will observe that I am careful to say the progress of science "at home and abroad;" for the study of Astronomy in this country has long since, I am happy to add, passed that point where it is content to repeat the observations and verify the results of European research. It has boldly and successfully entered the field of original investigation, discovery, and speculation; and there is not now a single department of the science in which the names of American observers and mathematicians are not cited by our brethren across the water, side by side with the most eminent of their European contemporaries.
