“ How grand is the ever-moving ocean! how majestic its voice, how terrible its anger! how beautiful every colour that is reflected from its dancing spray, and how balmy the air which is wafted from its bosom to refresh the heated earth, which, under the glare of a summer's sun, seems parched with thirst. ”

“ The slightest movement of the air communicates motion to the surface of such a great sheet of water as the sea, and this motion is gradually increased till one ripple meets another, and the power of both goes to form the next, so that they acquire a very considerable size; when a gale of wind blows, the rolling of the waves far out at sea becomes terrific, and they rise like mountains, chasing one another over the wide ocean. ”

“ Visit the iron works and see the powerful “steam hammer” moulding into form a mass of red-hot iron, many tons in weight; see the powerful and beautiful contrivances for rolling into plates, drawing into bars and wire, or cutting up this stubborn metal, and call it stubborn no more! See the powerful “locomotive” carrying along the trams hundreds of tons of goods at a rate that can hardly be equalled by the bird that flies through the air on its light pinions ”

“ When the surface of any portion of land has to be drained of its accumulated water, where the soil is of an impervious nature, like clay, it is usual to cut deep furrows from the higher to the lower parts and fill these up with gravel stones or brushwood; the moisture which collects in these is made to flow into the lowest part, and there form a pond, from which it evaporates as fast as the drains supply it; or if the quantity be too great, a main drain or ditch carries it onwards to some stream or river. ”

“ This earth is an enormous mass, contemplated in comparison with ourselves, but an insignificant speck when compared with the sun, and there are certain laws, chemical and mechanical, which govern them all—heat, light, and electricity permeate all the infinity of space—attraction exists everywhere. ”

“ The air is the great source from which all the nourishment of the organic creation, whether vegetable or animal, is derived; its carbonic acid is decomposed by the vegetables, which appropriate the carbon, turning over the oxygen to their companions, the animals; the ammonia of the air furnishes all the nitrogen of seeds and other nutritious parts of vegetables, which are eaten by animals; and water, the chief source of all nutriment, passes first from the air before it enters the soil, bringing both carbonic acid and ammonia to fertilise it. ”

“ The surface of a road should be slightly arched and a drain made on each side, that pools of water may not collect on its surface and soften it so that it will work into holes. Ordinary roads are made by laying down a stratum of broken granite or other hard stone a few inches deep, each piece being of about half a pound weight, when this first layer is worked in by traffic, a second is laid, and so on till the surface has become quite firm and level, but in the streets of towns more care is required. ”

“ The Earth, considered as one of those spheres which circulate round the sun amidst the wide expanse of the firmanent, holds but an insignificant position among them, especially when compared with those great and magnificent orbs, Jupiter and Saturn; but, in another point of view, as the dwelling-place of all the animated beings, vegetables, and minerals, with which we have any practical knowledge, it holds to us a position in creation far above all the others. ”

“ Wood is an article of universal application; its lightness, strength, and the facility with which it can be worked, render it almost invaluable; although in ship-building and many of its applications to house-building iron has to some extent superseded it, yet there are so many other ways in which it is indispensable, that it may be looked upon as one of the greatest boons to mankind. ”

“ The rapidity and ease with which thousands of troops were lately conveyed to the Crimea and India, together with all their stores, horses, &c., form one of the most wonderful feats of ocean navigation ever performed, and point out the beauty of those arrangements which enable man to traverse the whole earth, whether by land or by water, so that it may fairly be said that the civilisation of the world depended and still depends upon the waters. ”

“ Scarcely any kind of machinery can be constructed without wheels of some kind—they serve almost numberless purposes. The fly-wheel (fig. 1) serves to produce a continuous motion, from its size and weight giving it a tendency to go on, and in this way causing it to fill up the intervals of unequal action, as in the ascent and descent of the piston in a steam-engine. The toothed-wheel serves to give motion to other wheels, and this at a certain rate either greater or less than its own, according to its size, and consequently the number of its teeth ”

“ It is a wonderful sight, and one which fills our minds with reflection; here we see many of the laws of nature exemplified on a great scale. The laws of gravity keep the surface of the ocean perfectly spherical as a whole, while those of equilibrium keep it in constant and ever-varying motion, the laws of attraction produce the tides, and those of reflection and refraction cause its surface to assume all sorts of colours and tints. ”

“ It matters not whether the object to be wrought is the head of a pin, or the crank of a steam-ship, it is done with both delicacy of touch and power of arm, a hundredfold beyond what could be effected by hand in the same time. The motive power of steam is derived from the property which water has of being expanded into vapour when heated to a certain degree, and of again resuming the form of water when cooled; this moreover takes place in the most easily manageable manner, and either by degrees or suddenly, according as the heat and pressure balance each other ”

“ Of what use, to any creature but man, is coal—of what use the metals? Of what avail is it to any of the lower animals, that God has caused glass and other transparent substances to have the power of refracting the rays of light? but without which not one-half of our knowledge of His wondrous works would ever have been obtained, for it is upon this property alone that the powers of the telescope and microscope depend. Of what use to any but man are fire, artificial light, and galvanism? ”

“ But this world is one of perpetual change, and the coal thus brought forth from the depths of the earth, is by man being rapidly restored to the air from whence—thousands of years ago—it was derived; and it is not coal alone which is thus being restored, but every organic being in the whole creation, for at their decay they all enter this vast mausoleum of the dead! ”

“ THE VEGETABLE KINGDOM.
QUANTITY, DISTRIBUTION, AND OFFICES OF THE VEGETABLE.
In contemplating nature there are few things which give more delight than the beauty and variety of the vegetation which clothes the surface of the earth, whether it be that we contemplate the grassy covering of the plains of the Old World, or the immense "prairies" of the New, spreading out as it were into seas of grass, and giving food and shelter to thousands of wild animals ”

“ The comets traverse our system of suns, and passing onwards with incredible rapidity, for years upon years, through that great space beyond it, at last visit some other system—perhaps to be as much an object of regard and wonderment there as they were here. The same ray of light which emanated from one of the distant stars of some one of the clusters situated far out in space, and which has travelled for thousands of years at the rate of 200,000 miles for every second of time, serves us here on this globe to distinguish it—it enters the tube of our telescope and affects our optic nerve ”

“ On looking at the horizon we do not look on a perfect level, (if we did, being above it, of course we could not see it at all) but the depression of the line of vision is so slight as to be quite unable to be appreciated; yet, small as it is, it enables us to see a considerable space of the ocean, and the higher we rise—at the same angle—the more we see. The edge of the horizon also appears curved, being higher in front of us than on either side. ”

“ The immense preponderance of the vegetable over the animal world in quantity compensates somewhat for the superior organisation and the intelligence of the latter, which must be studied in the individual, while the vegetable world, which can be contemplated in the mass, almost overwhelms the imagination with its vastness. It is indeed impossible to compute the amount of vegetation in the great forests of America and Russia (in which latter country are the largest in the world) , covering hundreds, nay thousands, of square miles with one continuous growth of timber. ”

“ Just at a time when the great forests of the earth are fast disappearing, and with them the only other source of fuel for fires, this reserve of the old forests, which was then useless, serves man as a most excellent friend—more useful than gold or silver, more precious than diamonds or rubies! ”

“ The swarms of Locusts in Africa will sometimes cover many hundred square miles of surface, and in this space not a vestige of any vegetation would remain after their visit. The description of the prophet Joel is sublime: "The land is as the garden of Eden before them, and behind them a desolate wilderness: yea, and nothing shall escape them.... The earth shall quake before them, the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining."
