Report on the geology of the state of Maine . d sufficient room should beallowed for expansion, otherwise it will burst the kilns. The 54 TOPOGRAPHICAL GEOLOGY. granular dolomite will fall into powder, when burned ; butthis is no disadvantage, unless it is to be kept a long time, orshipped for a distant port. Magnesian limestone forms, whenburned, what is called hot lime, on account of the rapidmanner in which it slakes, when moistened with water, evol-ving great heat in a sudden manner. Having collected aseries of specimens, illustrating the nature of all the Thom-aston lime and marble quarries, we made several excursionsto the new and valuable localities of limestone, situate inCamden and Hope, intending to return to Thomaston as soonas our map of the town was completed, and the requiredstatistical information collected. Dr. Cochran kindly offeredto obtain answers to a series of questions, which I had givenhim in writing, which information being of statistical value,is inserted in the Economical department of the Dolomite Quarry near the West Keag River at the Marsh. a a Talcose Dolomite. We now proceeded to Goose River settlement, elevenmiles North from Thomaston, where valuable quarries oflimestone are wrought. On the point, near the village andclose to the sea shore, are the Beauchamps pits, where thelimestone is of excellent quality, and is largely quarried andshipped, in its natural state, to be burned elsewhere. Mostof the limerock burned at Goose River, is obtained at a placecalled the Lilly Pond quarries, where the rock forms a cliff30 feet high, and presents an inexhaustible supply. Thislocality is situated half a mile N. E. from Goose Riversettlement, near the margin of a little lake, from which the TOPOGRAPHICAL GEOLOGY. 55 quarry takes its name. Although the quarry has been openedonly four years, it is evident from the appearance of the cliff,that very large quantities of limestone have been are also a number of s
