They are the crystallizations of human history, of all that man enjoyed, of all that man has suffered, his victories and defeats, all that he has lost and won. Words are the shadows of all that has been; they are the mirrors of all that is. The ghosts also enlightened our fathers in astronomy and geology.

«Que des particules de la plus extrême ténuité, suspendues dans un liquide, puissent s'agglutiner entr'elles et former des couches verticales, c'est ce que nous avons la preuve en fait dans les albâtres, les agathes, et même dans les crystallizations artificielles. Mais qu'une pierre toute formée, de la grosseur de la tête, se soit arrêtée au milieu d'une parois verticale, et ait attendu l

In ten seconds I was digging out for my schoolmaster one of those family histories which lie embedded in the general grey soil of the past like lumps of quartz veined and streaked with the precious metal of passion and glittering here and there with the crystallizations of scandal. "You could make a story out of that," he said, when I had done talking and he had done laughing.

But among the infinite number of siliceous concretions and crystallizations, as well as those of an almost indefinite variety of other substances, all of which are attributed to solution, there is not the least vestige of any collateral operation, by which the nature of that concretion might be ascertained in the same manner.

The marble's bluish gray is relieved by sparkling crystallizations, and its unwrought blocks are handled with an ornamental effect in the piers, lintels, and arches, and well set off by a simple high-pitched slate roof, with terra-cotta hiprolls, crestings, and finials. The open porches are both ornamental and useful, taking the place of piazzas. The tower is embellished with a terra-cotta frieze.

It is this that must be explained in a mineral theory; and it is this great process of petrifaction to which the doctrine of infiltration, whether for the mechanical purpose of applying cohesive surfaces, or the chemical one of forming crystallizations and concretions, will not by any means apply.

The summit of the mountain is composed of scoria, and crystallizations of sulphur, with here and there heaps of lava; wherever a stick is thrust in, the opening immediately emits a volume of white smoke, and if the hand be applied to the aperture, it is soon withdrawn on account of the great heat. The mean temperature of the summit, during the months of July and August, is 37° Fahr.

The noise within the gulf resembled loud continuous thunderings, and after each successive explosion, there issued columns of white, and sometimes of black smoke. The crater presents the appearance of an inverted cone, the interior part of which is covered with crystallizations of salts and sulphur, of various brilliant hues red appeared to predominate, or rather a deep orange colour.

Crystallization is confessedly a phenomenon of inorganic matter; yet the simplest rustic observer is struck by the resemblance which the examples of it left upon a window by frost bear to vegetable forms. In some crystallizations the mimicry is beautiful and complete; for example, in the well-known one called the Arbor Dianae.

This is furnished by numerous salt springs of limpid water, which are continually welling up, overflowing their borders, and forming beautiful crystallizations. The Indian tribes of the interior are excessively fond of this salt, and repair to the valley to collect it, but it is held in distaste by the tribes of the sea-coast, who will eat nothing that has been cured or seasoned by it.
