After a lovely ride through the beautiful woodland we viewed Goat Island, having an area of 61-1/2 acres and a circumference of about one mile. A strip about ten rods wide and eighty rods long, has been washed away on the south side since the first road was made in 1818.
The distance surveyed along Green River from its mouth to the portage is 57 miles, the length of the portage 5-1/2 miles, the distance measured in exploration of the remaining portion of the boundary claimed by the United States 61-1/2 miles, making in all 124 miles.
Seven-eighths of 70 equals 61-1/4 feet. The width of the pond they measured it with tape line was found to be 60 feet, so Yan was nearest, but Guy claimed that 50 feet was within 10 feet of it, which was allowed. Thus there were two winners two who escaped dishwashing; and Hawkeye's bragging became insufferable.
The employment of long-focus lenses for coronal photography is thus facilitated, and the size of the image is proportional to the length of the focus. Professor Barnard, accordingly, depicted the totality of 1900 with a horizontal telescope 61-1/2 feet long, fed by a mirror 18 inches across, the diameter of the moon on his plates being 7 inches.
They indicated a marked deficiency of thermal radiations, implying for coronal light, in Professor Langley's opinion, an origin analogous to that of the electric glow-discharge, which, at low pressures, was found by K. Ångström in 1893 to have no invisible heat-spectrum. The corona was photographed by Professor Barnard, at Wadesborough, North Carolina, with a 61-1/2-foot horizontal "coelostat."
