Century Dictionary and Cyclopedia
- n. Same as tuft.
- An old spelling of tough.
- n. A volcanic fragmental rock, varying from coarse deposits made of materials resembling fine gravel in size to those which are like the finest sand. Corsi defines tufo as being similar in composition to peperino, but bearing the marks of having been transported by and deposited from water. The tophus of Vitruvius and Columella was of volcanic origin; that of Virgil and Pliny was calcareous. The tufo of the Italians, at the present time, is volcanic, and is the same rock which was designated by the Romans as lapis ruber; it closely resembles peperino (the lapis Albanus of the Romans), and does not differ, except in color and degree of compactness from the modern sperone (lapis Gabium), or from the socalled
manziana(lapis Anitianus). These are all fragmental rocks made up of more or less firmly compacted volcanic cinders and ashes, and are all included under the term tuff as used by English geologists.
