It is applied to every large mass of mineral matter that goes to form the Crust of the Earth, whether it be hard and strong, or soft and plastic. Thus, for example, gravel and clay, coal and slate, are called _Rocks_, just as well as limestone and granite. “Our older writers endeavored to avoid offering such violence to our language, by speaking of the component materials of the Earth as consisting of rocks and _soils_. But there is often so insensible a passage from a soft and incoherent state to that of stone, that Geologists of all countries have found it indispensable to have one technical term to include both, and in this sense we find _roche_ applied in French, _rocca_ in Italian, and _felsart_ in German. The beginner, however, must constantly bear in mind, that the term rock by no means implies that a mineral mass is in an indurated or stony condition.”--Lyell’s Elements of Geology, p. 4.] [Footnote 14: Lyell’s Elements of Geology, p. 7.] [Footnote 15: See Lyell’s Principles of Geology, vol. i., pp. 411-413.] [Footnote 16: See Jukes, The Student’s Manual of Geology, p. 125.] [Footnote 17: Professor Tyndall, Odds and Ends of Alpine Life.] [Footnote 18: Ecclesiastes, i. 7.] [Footnote 19: Page, Advanced Text-Book of Geology, p. 55.]
