"when the waves thereof roar; the Lord of hosts ** is his name." Isaiah Li. 15.

The first impulse of morion in created beings and its preservation is not the only thing remarkable on this head; there is another which deserves our most serious attention. Evcrv thing in nature is in motion. S. me of the bodies which compose the universe, have a constant motion from which they never depart, while that cf others is arbitrary and varied. Hjw comes it that so many different mriions all opposite to one another, do not derange the economy of the universe? The most simple and be t constructed clock-work often goes wrong, and lasts but for a short time. But the universe has endured for ages without the smallest change. And what wide difference is there not between a piece of clock-work, I will not fay the most simple, but the most complicated, and the machine.of the universe! From whom flows a regularity so wonderful? What cause preserves in so perfect an equilibrium so many contrary forces which would seem mutually to counteract and destroy each other? It is God alone, whose power is unbounded, and whose wisdom is unsearchable. He presides over all those various motions; he preserves and directs them, and prevents them from, interfering to their mutual destruction.

How many motives do not these confide^ rations furnish us with for adonng and magnifying the Creator! He is the author and preserver of this perpetual and universal motion, without which we could not exist. What gratitude does not such goodness deserve ? Let us reflect with attention on the advantages, and on the infinite pleasures ■which result from those motions which God hath communicated to animals; let us for this purpose suppose that we were totally deprived of them and

we we shall then be sensible of the full value of the benefit we derive from the hand of the Creator. The free motion of each of our own nnmbers. is still more necessary to us j the loss we woald sustain of them would be irreparable. What obligations then have we not to God who hath bestowed on us the power Of moving them, and who preserves to us that power! In truth, the man must be very ungrateful and veryunworthy of so great a bltssing, who does not employ so excellent a faculty to the glory of God by every exertion in his power.

CHAP. XI.

Op The Food Of Insects.

The subject of the last, Chapter presented an excellent opportunity of displaying the infinite power of the Creator j the present will open a vast field for reflection on his beunty and wife providence in the care he hath taken to furnish abundance of proper food for insects. All living creatures are under a necessity of taking nourishment for the preservation of life. Insects are not excepted from this general rule. It is true that there are many which can live longer without food than other animals; but they cannot exist without it altogether. The reason why some insects can fast for a long time, perhaps for a month or two, is that their humours being thicker their ani

mal spirits are not so soon or so easily dissipated1; They all dread the rigour of winter, and to shelter themselves from it they retire into warm places; there are however but few which lay up provisions to supply them during that season. The bodies of those that do not eat are of a particular contexture* especially as to what regards the circulation of the biood and humours. They are so framed as to lose nothing by transpiration, and consequently do not require food to repair their waste* They retire into Testing places where they continue in a state between life and death, till the heat of the fun acquires power to reanimate them, and to give birth to those substances on which they live. It is neither wind nor rain which makes them seek those retreats in which they reside without eating. Thus a stste of repose seems as natural to them as rest and sleep to the other animals. Towards the end of Summer, and even before the cold weather sets in, they are seen assembling in crowds like Swallows, and preparing for their winter repose.

A great diversity is remarkable in the tastes of infects. What is agreeable to one, disgusts another, and some eat with avidity, what others will not touch. There are also some which are not always content with the fame food. Like gluttons who devour every thing, these insects sometimes take one fort of food sometimes another. Some too from necessity will eat what they do not relish, and which they do noE generally feed on; but then they are so circumstanced that they must either eat or die. All are not so accomodating however as these 5 for a great number use but one fort of food, and will rather die than taste another.

What was observed in the Chapter on the habitations of insects may at* once shew how many things'

- they tiiey use as aliment, for they never fall to lodge in! places where their food is within their reach. Dust, moist or dry earth, sand, the hardest stones, and even iron itself, furnish theni with provision.

But plants are their most common food. Some brouse on the green blade, others gnaw the roots and stems. Some pierce the wood and feed on its fragments; others are not satisfied but with the tender buds. Some caterpillars devour the leaves of trees, and herbs, while others attack the very pith of the blant.

They do hot, betake themselves solely to those plants! ■ that are wholesome or of ah agreabie 'aste, but some insects prefer even such as are insipid and venomous'.' The wormwood, bitter as it is, feeds the caterpillar of the Phalœna Abfynthii, and this instance would be sufficient to refute the opinibn of some authors who1 have asserted that insects feed only on mild vegetables; but there are other examples; The Spurge, notwithstanding its'acrid and noxious qualities, is preyed opon by the Sphinx Euphorbiæ and the Phalæna castrensis;

Among the insects that eat the leaves, some touch Only the Upper surface, others only the under: others devour both, leaving nothing of the leaf but its fibres, the skeleton of which resembles a sieve. Many are so delicate tha't' they will be content with nothing but the tender flowers. Others attack only fruits and ^;rain; and are often found in the pods of peas, in pears,' apples, plumbs, &c. Corn, bread, cheese,, sugar, andi feven bocks are preyed upon-by different specie*)-, and many valuable manuscripts have fallen a sacrifice to f'heir voracity. The moth destroys woolen stuffs, as h but too well known.

N The

The sacred writers often borrow comparisons front this little animal. Job, describing the wretched conduion he,was reduced to fays," that he consumed as ct a rotten thing,, as a garment that is moth eaten."— Job xiii. 28. Among the threatnings which God made to the enemies of the faithful, the following is not one of the least terrible. "Ye people in whose *'• heart is my law, fear ye not the reproach of men, "for the moth snail eat them up like a garment, arid "the worm {hall eat them like wool." Isa. Lf. 7,8. "See, (says Baruch,) the purple which shines on the f( statues of false Gods. But it fhairiofe its lustre "and fade, and they themselves shall at last be de"youred by worms." Ch. vi. 70.- " Ye rich, fays St tt James, weep for the miseries that shall come upon *' you. Your riches are corrupted, and vour gar"ments moth-eaten. Ch. v. 1,2.

Insects prey upon one another. The Scolopendræ which live in dunghills, feed on a specie.-, of smallworm which also lives there. The tree bugs insert t-heir rostrum into the body of a downy caterpillar with yellow spots which is found on willows towards, the end of the season, and suck its blood. '1 here is a species of exotic ant which lives on spiders, and' these in their turn feed on flies, and sometimes onants. We likewise find flies that devour on'e another, and even the moth of the Silk worm. The ichneumons kill spiders, and afterwards carry them to their nests. One species, of Dragon-fly, (the Libellula puella) contributes very much to rid the atmosphere of flies and butterflies. Between it and the common cabbage butterfly a chace commences which resembles that of the hawk and the heron. Thedraon fly seizes the Fapilio in its flight, and holding it firm with his fore legs, devours it entirely. Some beetles feed on the aphides. I have mentioned already the lice that adhere to serpents and birds. I shall only
