Fissure eruptions, while not numerous, have been exceptionally extensive, as in the Deccan of India, and the Snake River plains of the Xorth- western United States. Siliceous lavas usually have a pasty or ropy consistency, and flow slug- gishly, while basaltic lavas are usually fluid and l!ow freely. The former build up volcanic cones of steep slopes, as in Central France, whereas basaltic lavas form volcanic cones of gentle slopes like those of Etna or the Hawaiian vol- canoes. Some lavas decompose and disintegrate with amazing rapidity and form a fertile soil for the vine. Others, but slightly different in com- position, present for centuries a firm unyielding surface to the elements. Lavas may be either compact or vesicular, slaggy, scoriaceous, or pumiceous.
