90 sometimes it rises more acute and more elevated; sometimes it is hemispherical; and sometimes its sides are perpendicular, its top flat, and as broad as its base. In short, it assumes at times the most whimsical shapes, and all these perhaps successively in the same morning. The Blue Ridge of mountains comes into view, in the Northeast, at about 100 miles distance, and, approaching in a direct line, passes by within 20 miles, and goes off to the Southwest. This phenomenon begins to shew itself on these mountains, at about 50 miles distance, and continues beyond that as far as they are seen. I remark no particular state, either in the weight, moisture, or heat of the atmosphere, necessary to produce this. The only constant circumstances are, its appearance in the morning only, and on objects at least 40 or 50 miles distant. In this latter circumstance, if not in both, it differs from the looming on the water. Refraction will not account for this metamorphosis. That only changes the proportions of length and breadth, base and altitude, preserving the general outlines. Thus it may make a circle appear elliptical, raise or depress a cone, but by none of its laws, as yet developed, will it make a circle appear a square, or a cone a sphere. 



THE NUMBER OF ITS INHABITANTS?

The following table shows the number of persons imported for the establishment of our colony in its infant state, and the census of inhabitants at different periods, extracted from our historians and public records, as particularly as I have had opportunities and leisure to examine them. Successive lines in the same year shew successive periods of time in that year. I
