Every Thing created has its Use.

151 which Providence designed them, and that belief is suf ficient for us. For certain things to take effect and be realised, perhaps, it is requisite that others should fail and appear defective. If it is true that wisdom is not entirely engrossed about the present, but extends its views to the future; if God is infinitely wise, and if his wisdom is to be manifested to the world as in a mirror; there must occur many things which, sepa rately considered, do not perfectly appear to accomplish their destination, because they required other causes to co-operate with them. The part which these have in the execution of the whole plan may be so imperceptible and so little understood, as entirely to escape our notice. But surely it does not follow, that because we cannot perceive the end they answer in the great system of nature, they do not contribute to its perfection, and are therefore useless; on the contrary, we have just reason to conclude, from what we see of the power and wisdom of God displayed in his works, that it is impossible for him to have created any thing without design, or without utility; though, from our imperfect nature, we are not always able to perceive the object and use of some of his works.

This firm persuasion will contribute to our peace and happiness; for there daily occur in nature, and in the course of human life, events, whose connec. tions, relations, and designs, appear to us incompre. hensible and of no utility, and which might otherwise weaken our faith in God, as well as hurt and distress our feelings. But the more we are convinced by reason, observation, and experience, and confirmed by the testimony of the Holy Scriptures, that God, as he is infinitely wise and powerful, so also he is infi nitely merciful and just; the more contented and cheerful shall we be in adversity as well as in prosperity. We shall then see and acknowledge, that all that God effects, or permits to be accomplished, is for

the wisest purposes, and always for the universal good of mankind. And when we observe in nature so many inexplicable events, seemingly repugnant to the divine plan, far from finding cause to complain, let us rather adore the wisdom of God, and ascribe unto him the glory which is due ; ever trusting to him for safety and support, and confiding in his power without the folly of cavilling at his dispensations. This submission to his will is the way to happiness here, and eternal felicity hereafter.

Harmony between the Moral and Physical World.

THE wisdom of God has established so great an affi. nity between the earth and its inhabitants, that they seem to be formed for each other. There is a certain connection and harmony which links together all the works of the creation. There is an evident analogy between the human body and the surface of the earth; as the bodies of plants and animals are formed, and come to maturity, then perish; so also are the bodies of men subject to similar changes. Such is the plan of the Creator, and it is pregnant with wisdom and goodness, adorned with perfection and beauty; it is only our imperfect knowledge which prevents our see. ing it as it is.

If any one objects, Why then has not God given to every one the same faculties and the same degree of intellect?" we may answer-Who art thou, blind mortal, that callest God to an account for his works? Shall the creature dictate to his Creator, or question his powers? As well might we ask, Why God has not so ordered, that all the countries on the earth, that every field, should be equally pleasant and fertile ?

The Moral and Physical World.

153

Why do we find in some parts a rich and fruitful soil, whilst others are so sterile and desert that all attempts to improve them are in vain ? There can be no doubt that this diversity is highly beneficial, and worthy of our warmest admiration, though not always conformable to our mode of thinking. The most desolate and barren regions, as well as the most wild and un, cultivated nations, have their beauty and use in the eyes of God; all hold that place which has been as. signed them, and which is best adapted to their na. ture, in the immensity of created beings; and their variety serves still to manifest the wisdom of God, which is infinitely diversified.

But as it is manifestly the intention of Providence that the earth should be cultivated, and produce fruits in abundance for the preservation of its inhabitants; and as for this end he has given us corn to sow the earth, and seeds of various kinds to supply food and nourishment; so also he has given to each individual a mind, which, according as it is cultivated, will bring forth fruit; it possesses all the capabilities of virtue and of happiness, and only requires the seed to be sown to produce a harvest rich and abundant. With this view he has given us lessons of true knowledge and religion, which, when received in a mind properly disposed and regulated, will produce exquisite fruit, and abundant as the corn planted in a fruitful field.

There are vast tracts of uncultivated and barren lands, where no verdure smiles, nor fruit refreshes, though they receive the fostering rays of Heaven; so also, notwithstanding the general diffusion of the Gos pel, there are countries which still remain in darkness, and there are people yet besotted by ignorance and infidelity. And among the civilised nations of the Christian world the influence of the Gospel is often very slightly felt; many people know not what it is,

do not comprehend it, nor have any idea of the saving power, and sublime truths, of a pure and holy reli gion. Others receive it with eagerness and joy, and for a space acknowledge its influence; but the impres sion is not lasting, and soon becomes obliterated. Some are too much agitated by the passions and concerns of the world to attend to the gentle monitor: but there are some who receive the Divine word with a heart pure and incorrupt; they hear its dictates with pleasure, and, by following them with perseverance, become of the happy number of the wise and prudent, whose steps are marked by virtue, sincerity, and peace, to whom it is indeed the power of God unte salvation.

Of the Nature and Properties of Air.

AIR is a subtle fluid, which surrounds our globe, and which all living creatures respire. Although it is so near us, every-where surrounds us, and we are continually experiencing its effects, we are not yet sufficiently acquainted with it to precisely determine its nature. We know that it is a substance, for when we pass our hand rapidly through it we find resistance ; and we are certain that it is fluid, its particles are easily displaced, and yield to all kinds of impressions. Were it solid, we could neither inspire it, nor move in it with facility. It possesses weight in common with other bodies, being about 816 times lighter than water.* The force with which the air weighs upon

*Its specific gravity, according to the experiment of Sir George Shuckburgh, when the barometer is at 30 inches, and the thermometer between 50 and 60 degrees, is 0,0012. One hundred cubic inches of air weigh 31 grains troy. Thomson's Chemistry.

Nature and Properties of Air.

every square foot of the earth is equal to a weight of 2160 pounds. And a man, whose surface is about fourteen square feet, sustains a weight of atmospheric air equal to 30,240 pounds. This may appear incredible; but the resistance of the air contained in our lungs prevents our suffering any inconvenience from the pressure of the external air, an equilibrium being thus preserved.

The elasticity of the air is equally certain; it is continually making an effort to fill a greater space, and, though capable of compression, as soon as the This is suffipressure is removed it again expands. ciently proved by means of heat, which rarifies it to such a degree, that it may be made to occupy five or six hundred times more space than it did before the heat was applied, without losing its elastic power. All these phenomena are highly worthy of admiration, and in them we may perceive the causes of many astonishing effects. It is in the air that our globe is suspended; and it is in the air also that the clouds are collected, forming so many beautiful shades and colours, and which, as they are rarified or condensed, suspend the vapours, or permit them to descend on the Without air life canearth, in rain, hail, or snow. not be supported, nor fire and water exist.

Thus then the air also announces the grandeur, power, and goodness of God, whose infinite wisdom alone could adapt this element to so many and various purposes. God creates and governs the rain, the, snow, the winds, the thunder, and the lightning; he measures the quantity, gravity, elasticity, and motion of the air, and mercifully causes it to serve our necessities, and contribute to the general welfare of our globe. Let us then, who every moment breathe this air which supports our lives, adore the depths of the riches of his marvellous wisdom and understanding, who alone has created all these things manifested in the whole economy of nature with infinite splendor!
