Albany: Weed Parsons, 1880. First edition. Hardcover. Colvin was the first to thoroughly explore the Adirondack Mountains and track it's environmental degradation. His advocacy led to the creation of New York's Forest Preserve and the Adirondack Park. The book contains the condensed reports for the years 1874-75-76-77 and '78. There are numerous maps & lithographic panoramic prints, which are very attractive. With late results in geodetic and trigonometrical measurements, magnetic variation, hydrography, river surveys, leveling and barometric-hypsometry, meteorology, rain-fall, botany, zoology and geology.
Blue publishers cloth, spine very marked but gilt lettering bright, boards somewhat marked but complete in a very tight binding. Two maps with tears going into the map about a quarter (Map 4 & 5). Several plates are fold outs, approx. 3 in color. The last f/o plate, #32, p362, had been detached, now reattached with archival tissue. Maps 1-7, 3 maps b/w, others with some color. Good overall.
