It has often been a wonder with the curious, why enlistments take place in times of profound peace; and the probable causes that lead to such steps are, of course, much debated. We remember seeing, not long ago, in the newspapers, a brief table of such causes, purporting to come from an army surgeon who examined each recruit on the subject. It was funny, and so startling withal, that while some laughed or stood aghast, others hardly knew which to admire most, the doctor's eccentricity, or his fertile fancy. We know not if in the world's vast library there is any reliable exhibition of such causes. Sir Walter Scott's imaginary Clutterbuck, after some prefatory doubts, leaves the following as perhaps his principal reason: "This happy vacuity of all employment appeared to me so delicious, that it became the primary hint, which, according to the system of Helvetius, as the minister says, determined my infant talents towards the profession I was destined to illustrate." Such may be the idea of some at the present day, though Clutterbuck's declaration is by no means sacred authority. He confesses he was unmilitary enough to damn reveillé, and also, to a significant rebuke from his old colonel. "I am no friend to extravagance, Ensign Clutterbuck," said he, "but on the day when we are to pass before the sovereign of the kingdom, in the name of God, I would have at least shown him an inch of clean linen." The truth is, the causes are about as various as the trades they subscribe to, or, if one more than another be predominant, it is "the love of the thing." In the old countries, the drum and fife mingled their music with the first pleasant scenes he ever saw; and, in the new world, the same enlivening sounds also awoke the spirit of childhood. Early associations had merely lain dormant for a season, but those connected with the bright musket and sabre were stronger than those of the spade and figure-maker's mould.

Having before us the roll of a company now in service, we will take from it such information as may be pertinent, premising that the record is so nearly like that of every other, that the little difference, as mathematicians say, may be disregarded without affecting the general result. Of the whole number (fifty), thirty-eight are between twenty and thirty years of age, ten between thirty and forty, and two between forty and forty-five. Five were born in England, three in Scotland, twenty-one in Ireland, five in Germany, thirteen in the United States, two in Prussia, and one in Italy. They subscribed, at the time of enlistment, the following trades: five farmers, one spinner, twelve laborers, one weaver, one tinsmith, one painter, two gardeners, three bakers, two shoemakers, two tailors, one carpenter, one printer, one cigar-maker, nine soldiers, four clerks, one turner, and one figure-maker (the Italian); and one pretends to be a lawyer, though, as he may be an imposter, we will have due regard for the sensitive feelings of our legal friends, and set him down as only a pettifogger. Sixteen cannot read or write, and of these, three are of the United States, and the remainder nearly all from Ireland. It is quite a treat in chirography to see the signatures of the residue of the fifty, as they stand in the column. They are not so imposing as John Hancock's on the Declaration, nor as small as a schoolmistress's copy; but assume all shapes and styles, from the "clerkly fist," to the genuine "crow-track," or Chinese characters on a tea-chest.

Be it as it may, after he swears to serve well and faithfully the United States against all her enemies and opposers whatsoever, he is sent to New-York harbor, if he is to do foot-work, or to Carlisle Barracks, if a horse is to do it for him; and in one of these places the transformation from civil to military life begins. In two hours after his arrival you would hardly know him. With hair cut close, and a complete revolution in his dress, he looks nothing like the "sovereign" of this mighty Republic you have just seen. He feels the change, too; and as he struts up and down, peacock-like, admiring himself, he realizes that hitherto, for many years perhaps, he has not had a new suit from tip to toe all for nothing. It has saved him weary days of toil, and the little personal liberty he has given in exchange is but dust in the balance. As soon as "the vapors melt into morn," the drum sounds the reveillé, and up he rises to receive instructions, which are repeated and repeated until he has them at his tongue's and fingers' ends. At all times, if well-behaved, he receives the necessary recreations and indulgences. To follow him closely throughout his tuition, would be to extend this article more than is intended, besides outraging the military knowledge of many by a recital of elementary instruction. Suffice it to say, after a certain period, he is sent to some post on the sea-board, or to active service on the frontier.

The term of enlistment varies in different countries. In England, formerly, it extended to twenty-one years; but the law has lately reduced it to ten. In our service it is for five years only, with the privilege of re-enlisting, if at the end of that time the applicant is still sound in body and mind. He then becomes an "old soldier;" a term which, for some reason or other, is used in civil life with no complimentary import. It has a better meaning in service, however, which is well exemplified in the French proverb, "Il n'est chasse que de vieux chiens" (old dogs are staunch hunters). The pay also varies, and it is a feather in the cap of our Government that we may say she is in this respect more liberal than any other. In France, Prussia, Germany, Austria, and Russia, a private, with all economy, cannot save more than six cents a-day; yet when we consider the vast number each is obliged to keep under arms, we cannot suppose them able to pay more. England, whose "public debt is a public blessing," also looms up largely in the battle array, and pays better than her neighbors. With her artillery-private (or gunner as he is more properly called), we will compare a private of the United States artillery, or infantry, since both are on a par in this respect. The former receives one shilling fourpence farthing, or thirty-three and one-half cents, per day, from which, deducting his rations and clothing, there will be left thirteen and one-half cents, or about four dollars per month. The latter receives seven dollars per month, beside his rations and clothing. In the British infantry regiments, the private has but one shilling per day, and the Queen graciously allows him one penny of "beer-money."

The artillery-company of England is perhaps the best organized and most efficient in the world; while ours is merely nominal, and a sore subject to the accomplished officers attached to it. It is called artillery, but infantry is more appropriate. At nearly all the forts, the siege pieces and implements of the artillerist are packed away in storehouses, without a particle of benefit to those for whom they are intended. In Mexico, on the march to Orizaba, it had the mortification to trudge along on foot, while midshipmen commanded sections of a light battery, marines were cannoneers, and sailors rode the horses, using, in their amphibious state, the oddest medley of sea-terms and military jargon that ever grated on professional ears. It would have been equally proper to put an artillery captain in command of the frigate Cumberland then lying in the harbor of Vera Cruz, with no less a prospect of brilliant manœuvres in the hour of battle. The English company is really what it purports to be, and is one hundred and twenty strong, including eight corporals and four bombardiers; besides, it has eight serjeants, three buglers, one second and one first lieutenant, one second captain (brevet-captain in our service), and one first captain. The aggregate here is fifty-eight, not quite one-half of the British company.

It will be seen, from what has been said, that the Greenwich dragoon, or foot soldier, is, in five cases out of six, either a Dutchman, Irishman, or American; and an observer can easily perceive in each his national characteristic and temperament. Karl is dull and heavy, generally sober, always ready to lend his pipe, or sing a song. Pat is merry, loves a glass at any time, is handy with the spade, and uses his mother-wit in rounding off a capital story. Jonathan is all these, and something more. He astonishes his trans-atlantic comrades by the incomprehensible manner in which the knave will turn up when he deals the "pictures;" and the neat manner in which he mends the rent in his coat sleeve; is one short of funds, he will generously lend him a safe amount until "next pay day," provided, at that time, fifty per cent. be added thereto; and, if some doubt arises in the mean time, he disposes of his stock to some other speculator; so that Wall-street-like panics are not unfrequent—sometimes among the bulls, sometimes among the bears. If he chooses, he will do more work in less time, or less work in more time, than Karl or Patrick, and he often manages to make a cats-paw of them to scratch out his delinquencies. He knows well how to make use of the technicalities of the limited monarchy under which he is governed, and bewilders dull Karl by his manifold risks and little punishment.

It matters not whether our man is cooped up at Eastport, or bivouacked on the Rio-Grande—he is every where essentially the same. With scarce a thought beyond the morrow, he awaits it without impatience. In all places, and at all times, he has great respect for his officer; the gracefully touching his cap being no idle ceremony. At the close of a weary day's march, he will leave his own to put up his tent; build a fire near it, and do every favor he can, freely and willingly. Officers will recognize this fact, and attribute the secret to the strict non-familiarity between them.

He has three festivals during the year, when he sets a splendid table and enjoys himself—the two wintry holidays, and the anniversary of our national independence. There are songs and speeches in abundance, and the oratory is genuine. If he lingers long at the table—or under it—there is so much power in the "star spangled banner," or "Erin is my home," that he must become a martyr to their glorious enthusiasm. On one of these occasions, a little lady friend christened an aldermanic German by a patriotic name which since has taken the place of his own. "He was a man of an unbounded stomach," seemingly, with the French maxim ever uppermost in his mind: Quand la cornemuse est pleine on en chant mieux (when the belly is full, the music goes better). An escopette ball at Molino-del-Rey struck him on the head, and the ponderous mass rolling over and over on the ground, he was left for dead, but his time had not yet come. It was a heavy blow, and though alive, yet his reason, at times, is gone: predicting something novel in the history of man to happen on the 4th of April next. Another joyful day is the visit of the paymaster, which happens six times a year. His last supply is gone—hence his anxiety to replenish. He is very happy to see this financial individual—as much so as any body was with the arrival of the first California steamer with two millions in gold. His only drawback is, that his mortal enemy, the sutler, is then invariably ready to face him with a small bill for sundry articles, such as cheese, whiting, and "some drinks." He had no idea it was so large! Generally he pays to a fraction; sometimes, like broken banks, he compromises for a certain per centum; sometimes he repudiates in toto. He is often economical, spending nothing, and transmitting his savings to destitute relations at home or abroad. A thousand hearts were gladdened, and a thousand mouths fed, in the poor Emerald Isle during her starving days, by five pound drafts from "the bold soldier-boy" over the water. These substantial tokens from the home of his adoption have a secret but visible effect. The military roads he lays out are found and followed by the recipients of his bounty, and gardens flourish where but yesterday were seen the poles of his old camping ground; new states rise out the wilderness, where he planted the early seed, and watched the glittering things as they grew to the strength and beauty of their starry sisters.

He has no enmity or prejudice against any person, sect, or society—loving Broadbrim even more than could reasonably be expected. There is, however, a proverbial enmity between him and Jack the sailor, though it is generally of that Pickwickian nature, that—like Micawber's griefs—easily dissolves over a bowl of punch, and both become as jolly as Friar Tuck and Richard. He is not generally religious; but during divine service is as orderly as a deacon. Sometimes he pleads conscience against Protestant worship, but those interested may be assured that, in five cases out of six, it is only Pat's cunning: true piety can worship God under any form. He is generally a bachelor, and rarely goes beyond the walls for a wife: if Abigail comes inside, he snaps her up as you would a hotcake on a frosty morning. If he dies prematurely, some comrade is ready to console the widow in her affliction; the courtship being a fine exemplification of—

"For you must know a widow's won
With brisk attempt and putting on:
With ent'ring manfully and urging—
Not slow approaches like a virgin."
