Էջ 555 - ... has become more or less stained with iron oxide and is known by geologists as the yellow gravel. From the western end of Long Island the yellow gravel extends southwestward across Staten Island and the lowlands of New Jersey; and it is to be regarded as one of the most important as well as one of the latest formations of the Atlantic seaboard. It belongs chiefly, at least, to the Lafayette division of the Neocene period; while the underlying blue clay and gray gravel may be referred, provisionally,...
Էջ 560 - ... it will probably be clearer to the general reader and more useful, we now enumerate only the principal or heavier ones. They are as follows, commencing at the base along the Delaware river and passing eastward so as to reach successively higher and higher horizons : No. 1, First Horizon — A group. This may be defined as a group of two or three horizons in heavy gravel and cobble strata near the base of the plastic clays, which clays are variously colored white, yellow and red, or they are mottled...

The following table gives, where known, the approximate interval in feet from the top of one horizon to the top of the next: WATER...

Croton water, in gallons per day, has been accurately measured, with the result of showing that the estimates of consumption and of growth in consumption of water made by the Department of Water Supply at the time the Ramapo contract was urged were about forty million gallons per day too large." " A very full geological study of the deep subterranean strata of Long Island and of Staten Island has been made with a view to learning of the possibility of a supply from deep wells, and of the best...

Էջ 567 - Ward of Brooklyn gave : Loam and fine sand, 10 feet ; water-bearing gravel, 25 feet ; clay, I foot ; sand and gravel, 35 to 65 feet ; and then clay (probably the blue clay). The collective yield of these wells is 2,000,000 gallons in 24 hours. The yellow gravel is, evidently, the surface formation here. The well at Malcolm's Brewery, in Brooklyn, 62 feet deep, presents similar conditions.
