Not illustrated. 1921 Excerpt: ...sand pit at Albany Junction on the Atlantic Coast Line Railroad 2J4 miles southwest of the Albany court house. The pit covers several acres, and the exposed face ranges from 15 to 30 feet in height. The sand is pale yellow, composed entirely of quartz, and is remarkably clean and uniform. Faint stratification lines dipping from 30 to 40 to the eastward and consisting of slightly coarser grains in layers i inch thick and with from 2 to 6 inches between the layers, occur in the lower two thirds of the deposit. Practically no silt or clay is in the sand, although the clay substratum is exposed in places in the pit floor. The undulating topography of the sand hill, visible from the top of the pit banks, consists of small hills reaching a maximum of 40 feel above the railroad grade with intervening valleys or depressions where the clay appears to come very close to the surface. Sample T-210 from this pit has a fineness modulus of 2.04 and 88 per cent is retained on the 48-mesh sieve. Only a trace of organic matter occurs. The sand from the pit is used in the manufacture of sand-lime bricks which are said to compare very favorably with clay brick in strength and price. The sand from the pit is shoveled into a tram-car hauled by a small electric locomotive which deposits it on a bucket elevator by which it is delivered to a bin in the upper part of the brick plant. The sand is fed from this bin to a short belt conveyor from which an arbitrarily regulated portion (usually 15 per cent) is removed by a scraper and allowed to pass into a tube-mill where it is thoroughly ground and mixed up with the caustic lime which forms the binder. The tube mill is 5 by 22 feet and made by the Power & Mining Manufacturing Company. The sand and lime are ground until 90 per cent ...
