Sivu 601 - Let us not then refuse to believe even what we do not see, and let us supply the defects of our corporeal eyes, by using those of the soul ; but especially let us learn to render the just homage of respect and veneration to the Divinity, whose will it seems to be, that we should have no other perception of him than by his effects in our favour. Now, this adoration, this homage, consists in pleasing him, and we can only please him in doing his will.
Sivu 321 - ... lose all force of growth, all power of reproduction. Onr great investigators have given us sufficient work for a time ; but if their spirit die out, we shall find ourselves eventually in the condition of those Chinese mentioned by De...
Sivu 358 - The little orifices from •which the hot water issues are beautifully enameled with the porcelainlike lining, and around the edges a layer of sulphur is precipitated. As the water flows along the valley, it lays down in its course a pavement more beautiful and elaborate in its adornment than art has ever yet conceived. The sulphur and the iron, with the green microscopic vegetation, tint the whole with an illumination of which no decoration-painter has ever dreamed. From the sides of the oblong...
Sivu 626 - A broad chasm is to be spanned before we can link the Mound Builders to the North American Indians...
Sivu 158 - ... the varieties of oak which are seen scattered over them, interspersed at times with pine, black-walnut, and other forest-trees, which spring from a rich vegetable soil, generally adapted to the purpose of agriculture. The surface is ordinarily dry and rolling. The trees are of medium growth, and rise from a grassy turf seldom encumbered with brushwood, but not unfrequently broken by jungles of rich and gaudy flowering plants and of dwarf sumach. Among the "oak-openings...
Sivu 534 - Pear-trees are particularly subject to their attacks, but the elm, hickory, poplar, oak, and probably also other kinds of trees, are frequented and injured by them.
Sivu 627 - The distinctive character of the Mound-Builders' structures, and also the traditions which have been preserved, would indicate that this people were expelled from the Mississippi Valley by a fierce and barbarous race, and that they found refuge in the more genial climate of Central America, where they developed those germs of civilization, originally planted in their northern homes, into a perfection which has elicited the admiration of every modern explorer...
Sivu 292 - Here this vapor collects, and presses the water in the cavern downward until its elastic force becomes sufficiently great to effect a passage through the column of water which confines it. The violent escape of the vapor causes the thunder-like subterranean sound and the trembling of the earth which precedes each eruption. The vapors do not appear at the surface till they have heated the water to their own temperature. When so much vapor has escaped that the expansive force of that which remains...
Sivu 288 - No water could be discovered, but we could distinctly hear it gurgling and boiling at a great distance below. Suddenly it began to rise, boiling and spluttering, and sending out huge masses of steam, causing a general stampede of our company, driving us some distance from our point of observation. When within about forty feet of the surface it became stationary, and we returned to look down upon it. It was foaming and surging at a terrible rate, occasionally emitting small jets of hot water nearly...
Sivu 321 - Secondly, the teacher of natural trutli, whose vocation it is to give public diffusion to the knowledge already won by the discoverer. Thirdly, the applier of natural truth, whose vocation it is to make scientific knowledge available for the needs, comforts and luxuries of life. These three classes ought to coexist, and interact...
