[8] The smaller works of Phillips and Aikin were not then published; had they been, they could not have superseded Cleaveland; the same may be said of the respectable work of Professor Kidd, of Oxford University. [9] A vast region in the interior of New-York and Pennsylvania is now fertilized by inexhaustible beds of sulphat of lime, (plaster of Paris,) which, till a very few years since, were not even known to exist. Near New-Haven immense beds of green marble were discovered in 1811, during a mineralogical excursion: this beautiful material, closely resembling the _verd antique_, is now, on the spot, wrought into tables, fireplaces, and many other ornamental forms; and although the farmers had made fences of it for 150 years, no one suspected what it was till the study of mineralogy, in Yale College, brought it to light.

[12] No return of this tree was made from Brunswick. The date of the cherry-tree is therefore substituted, which is usually in blossom at the same time.
