“ What a comfort to man, for whom that system was contrived, as the only living being on this earth who can perceive it; what a comfort, I say, to think that the Author of our existence has given such evident marks of his good-will towards man, in this progressive state of his understanding! What greater security can be desired for the continuance of our intellectual existence,—an existence which rises infinitely above that of the mere animal, conducted by reason for the purposes of life alone. ”

“ If we shall suppose the continent of our earth to be a solid rock, on which the rain might fall, and the wind and waves might dash perpetually, without impairing its mass or changing its constitution, what an imperfect world would we have! ”

“ L'arène ou se réunissent toutes ces eaux et où commence le Gave, est de forme irrégulière; sa surface inégale offre tantôt de grands plateaux de neige, des blocs de rochers écroulés et d'autre débris atténué et réduits à l'état terreux où végètent de belles plantes que le soleil éclaire à peine. Le Gave, en tombant sur les amas de neige, y a creusé un gouffre au fond duquel le soleil avant son déclin peint le cercle coloré de l'iris. Les eaux disparoissent sous la neige et renaissent ensuite comme sous un pont étroit ou sou la voûte d'un aqueduc ”

“ Thus there is a system of mountains and valleys, of hills and plains, of rivulets and rivers, all of which are so perfectly connected, and so admirably proportioned, in their forms and quantities, like the arteries and veins of the animal body, that it would be absurd to suppose any thing but wisdom could have designed this system of the earth, in delivering water to run from the higher ground; or that any thing could have formed this beautiful disposition of things but the operation of the most steady causes ”

“ On se trouve fort élevé au-dessus du Rhône quand on est sur le haut de ce chemin, dont on découvre un de plus singuliers, des plus riches, et de plus variés passages qu'on puisse imaginer. On voit sous ses pieds le Rhône serpenter dans le lit qu'il se creuse actuellement, car il change et tout prouve qu'il en a souvent changé; une quantité prodigieuse de petites isles le séparent et le coupent en une multitude de canaux et de bras; ces isles sont couvertes les unes d'arbres, d'arbustes, de pâturages, de bosquets et de verdure, d'autres de pierres, de sable, et de débris de rochers ”

“ Toute la surface de la terre, les rocs les plus durs, les sables et les graviers les plus arides, les métaux même, éprouvent l'action rongeante de l'air et leurs particules atténuées, décomposées, recomposées de mille manières, sont probablement la source principal de la végétation. L'air lui-même ainsi que l'eau, s'y combinent: beaucoup d'observations et d'expériences nous prouvent que ces deux fluides fournissent leur propre substance aux parties solides des végétaux, et par conséquent à la terre végétable qui les produit et qu'ils déposent. ”

“ Not only are no powers to be employed that are not natural to the globe, no action to be admitted of except those of which we know the principle, and no extraordinary events to be alledged in order to explain a common appearance, the powers of nature are not to be employed in order to destroy the very object of those powers; ”

“ Whatever changes take place from the operation of internal causes, the habitable earth, in general, is always preserved with the vigour of youth, and the perfection of the most mature age. We cannot see man cultivate the field, without perceiving that system of dry land provided by nature in forming valleys and rivers; we cannot study the rocks and solid strata of the earth, those bulwarks of the field and shore, without acknowledging the provident design of nature in giving as much permanency to our continent, as is consistent with sufficient fertility ”

“ Those water formed plains which we perceive subsisting at unequal levels immediately adjoining to each other, while they present us with a view of the degradation of the elevated earth, at the same time illustrate the indefinite duration of a continent; for, we judge not of the progress of things from the actual operations of the surface, which are too slow for the life of man, and too vague for the subject of his history, but from the state of things which we contemplate with a scientific eye, and from the nature of things which we know to be in rule. ”

“ When philosophers propose vague theories of the earth, theories which contain no principle for investigating either the general disorder of strata or the particular form of mountains, such theories can receive no confirmation from the examination of the earth, nor can they afford any rule by which the phenomena in question might be explained. This is not the case when a theory presents both the efficient and final cause of those disorders in bodies which had been originally formed regular, and which shows the use as well as means for the formation of our mountains. ”

“ Si un observateur attentif parcourt les plaines immenses de l'Amérique méridionale, s'il monte les fleuves rapides et profonds qui les traversent, et les inondent, et s'il franchit les montagnes prodigieuses que l'action des eaux détruit, il apercevra bientôt qu'un développement successif et inévitable de ce nouveau continent tend à l'agrandir dans tous les sens, et rendra peut-être un jour sa surface égale à celle de notre hémisphère. ”

“ This reasoning is, indeed, very far removed from that which is commonly employed for the purpose of conducting human operations, or establishing the political system of a nation; it is not, however, the less interesting to man, in that it cannot direct him immediately in his worldly affairs; and it is the only way of reasoning that can be employed in order to enlighten man with a view of those operations which are not to be limited in time, and which are to be concluded as in the system of nature, a system which man contemplates with much pleasure, and studies with much profit. ”

“ It is this operation of nature which we see performed, more or less, every day, which some natural philosophers have such difficulty in admitting at all, and which others overlook in seeking for some wonderful operation to produce the effect in a shorter time. The prodigious waste that evidently appears, in many places, to have been made of the solid land, and the almost imperceptible effects of the present agents which appear, have given, occasion to those different opinions concerning that which has already happened, or that natural history by which we are to learn the system of this world. ”

“ In all countries of the earth, whether of primitive masses or those of secondary formation, whether uniform and homogeneous, or compound and mixed of those two different kinds of bodies, the system is always the same, of hills and valleys, lakes and rivers, ravines and streams: no man can say, by looking into the most perfect map, what is primary or what secondary in the constitution of the globe. ”

“ In studying this part of the economy of nature, we may perceive the most perfect wisdom in the actual constitution of things; for, while it is so ordered that the solid mass of earth should be resolved for the purpose of vegetation, the perishable soil is as much as possible preserved by the protection of those solid parts; and these consolidated masses are resolved in so slow a manner, that nothing but the most philosophic eye, by reasoning upon a chain of facts, is able to discover it. ”

“ «L'Angle même de la montagne est partagé par une fente qui le traverse de part en part. Cette profonde fissure mérite qu'on la voye, et même qu'on la pénètre. Elle est tortueuse, et dans quelques endroits si étroite, qu'à peine un homme peut il y passer. Quand vous y êtes engagés vous trouvez des places ou les sinuosités du rocher vous cache le ciel, plus loin elles le laissent apercevoir par échappées; ailleurs vous voyez des blocs de rochers engagés dans la crevasse, et suspendus au-dessus de votre tête.» ”

“ But, between those two extremes, of mountains covered with perpetual snow, and parched plains in which every living thing must perish, we find the most pleasant subject of contemplation, in studying the means employed in nature for producing the beautiful and benevolent system of hills and valleys, of fertile soils and well watered plains, of the most agreeable circumstances and proper situations for every thing that lives, and for the preservation of an indefinite variety of organised bodies which propagate their species. ”

“ Now, whatever may be our theory with regard to the origin or formation of these solid masses of the globe, this must be concluded for certain,—that what we see remaining is but a specimen of what had been removed,—and that we actually see the operations by which that great work had been performed: we only need to join in our imagination that portion of time which, upon the surest principles, we are forced to acknowledge in this view of present things. ”

“ Nous pouvons accélérer de bien des manières la transformation des matières terrestres en terre végétable. La fermentation, la calcination, une plus grande exposition à l'air, différens mélanges, rendent propres à la végétation, des matières qui ne l'étoient par elles-mêmes: voila ce que peuvent nos soins. Mais l'air travaille sans cesse et en mille manières. Son simple frottement sur tous les corps, en enlève des particules si atténuées que nous ne les reconnoissons plus. ”

“ We have but to consider the surface of this earth as having been upon a higher level; as having been every where the beds of rivers, which had moved the matter of strata and fragments of rocks, now no more existing; and as thus disposed upon different planes, which are, like the haughs of rivers, changing in a continual succession, but changing upon a scale too slow to be perceived. ”

“ Ces monticules avec leurs fabriques s'élèvent au-dessus de tous ces objets variés; quelques-unes se distinguent par leur côtés écroulés qui sont à pic; la blancheur de ces éboulemens contraste singulièrement avec les verts qui sont les couleurs dominantes du vallon. Au-de-la des coteaux, des montagnes s'élèvent et vont s'appuyer et s'adosser à ces masses, à ces colosses énormes de rochers à pic élevés comme des murailles et d'une hauteur prodigieuse qui forment cette barrière qui sépare le Vallais de la Savoie. ”
