Rh Society presented for the consideration of the Assembly a plan for the prosecution of discoveries in astronomy, geography, and navigation, to which they said they were urged by some of the greatest men of Europe. It contemplated the erection of a public observatory, by subscription, upon a lot of ground to be granted by the proprietaries, who had expressed their concurrence. It should be furnished with the necessary instruments, which would be of but little expense, because the gentleman who it was proposed should conduct the design was capable of constructing them all in the most masterly manner. He should receive an annual salary both in the capacity of public astronomer and as surveyor of roads and waters. Here the captains and mates of vessels, and young men desirous of obtaining practical knowledge, should be taught the use of instruments and receive other instruction, and the observations made should be published annually for the benefit of learned societies at home and abroad. “We have a gentleman among us,” they went on to say, “whose abilities, speculative as well as practical, would do honor to any country, and who is nevertheless indebted for bread to his daily toil, in an occupation the most unfriendly both to health and study.” To give him an occasion to use his genius for the advantage of his country would be an honor which crowned heads might glory in, but which Pennsylvania ought not to yield to the greatest prince or people on earth. Should the present opportunity be neglected, whole centuries might not afford another.

The fact that such a design should be seriously proposed and favorably entertained at that early period shows a remarkable appreciation of the abilities of Rittenhouse, and a regard for the interests of science which is certainly creditable to the society, the Legislature, and to public
