Another invention of which the public have heard no little discussion lately is the reaping machine. To the American nation doubtless belongs the credit of forcing it into notice and into use; but as for any claim to the invention, it is equally certain they have none. That honour is due solely to the Rev. Patrick Bell, a Scotch minister in the presbytery of Arbroath. He first tried his reaping machine in August, 1828, at his father's farm on Lord Airlie's estate, where it has been in yearly use ever since; and in October he exhibited it at the Highland Society's meeting at Glasgow. The principle upon which his first machine was made differs in nothing from those making at this hour; and, as some of the people employed on his father's farm migrated to America, it is only reasonable to suppose they carried sufficient information with them to explain the machine. American ingenuity soon copied, and American energy soon gave an impulse to, Mr. Bell's machine, for which, though denying them the invention, we ought not to deny them our thanks.

But while I thus explain the unwarrantable claims which Americans have set forth, I must not allow John Bull to lay the flattering unction to his soul that none of his claimed discoveries are disputed on the other side of the Atlantic, I have seen a Book of Facts printed in America, which charges us with more than one geographical robbery in the Arctic Seas, in which regions, it is well known, American enterprise and sympathy have been most nobly employed. As I am incapable of balancing the respective claims, I leave that subject to the Hydrographer's office of the two countries.

The citizens of the Republic have but little idea of the injurious effects which the putting forward unwarrantable claims has upon their just claims. I have now before me a letter from a seafaring man who has spent a quarter of a century upon the borders of the United States; he is writing on the subject of their claims to the invention of steam, and he winds up in these words:—"They are with this, as they are with every other thing to which either merit or virtue is attached—the sole and only proprietors and originators, and say both the one and the other are unknown out of the universal Yankee nation." I do not endorse the sentiment, but I quote it to show the effect produced on some minds by the unfounded claims they have put forward.

They have ingenuity and invention enough legitimately belonging to them for any nation to be justly proud of, without plucking peacock's feathers from others, and sending them throughout the length and breadth of the Republic as the plumage of the American eagle. How many useful inventions have they not made in machinery for working wood? Is not England daily importing some new improvement therein from the American shores? Look again at their perfect and beautiful invention for the manufacture of seamless bags, by Mr. Cyrus Baldwin, and which he has at work at the Stark Mills. There are 126 looms in operation, all self-acting and each one making 47 bags daily; the bags are a little more than three and a half feet long, and chiefly used, I believe, for flour and grain. When they are finished, sewing-machines are at hand, which can hem at the rate of 650 bags each daily. This same gentleman has also adapted his looms to the making hoses for water, of which he can complete 1000 feet a day by the experimental loom now in use, and it is more than probable these hoses will entirely supersede the use of the leather ones, being little more than one-tenth the price, and not requiring any expense to keep in order.

Another and very important purpose to which their ingenuity has applied machinery is, the manufacture of fire-arms. It has long been a matter of surprise to me, why so obvious and useful an application of machinery was neglected by the Government at home. The advantages of being able to transfer all screws, springs, nipples, hammers, &c., from one musket to another, are so manifest to the most infantine comprehension, that I suppose they considered it beneath their notice; nor can I make out that they have duly inquired into the various breech-loading systems used in the States, some of which they have been testing in their Navy for years. As, however, we are beginning to copy their application of machinery, I dare say the next generation will take up the question of breech-loading arms.

A few observations on the Militia appear to follow naturally after remarks on fire-arms. According to the most reliable information which I have been able to obtain, every able-bodied male between 18 and 40 years of age is liable to militia service. Those who do not serve are subject to a fine, varying in different States, from 3s. upwards; which sum helps to pay those who do duty. The pay of a private while on duty is about 10s. a-day, and that of officers in proportion. Formerly, they only turned out two days in the year; now I believe, they generally turn out ten, and in some of the cities twenty, days annually. The persons excused from militia service, are the clergy, medical men, fire companies, and those who have held a commission for three years. Each regiment settles its own uniform; and it is a strange sight to see companies in French, German, and Highland uniforms, all marching gaily through the streets.

The day of firing at a mark is quite a fête; they parade the town, with the target untouched, on their road to the ground: there they commence firing, at 100 yards; if the bull's-eye be not sufficiently riddled, they get closer and closer, until, perforated and in shreds, it scarce hangs together as they return through the town bearing it aloft in triumph, and followed by all the washed, half-washed, and unwashed aspirants to military glory.

I believe the good sense of the people is endeavouring to break through the system of nationalizing the companies into French, German, Highland, &c., believing that keeping up such distinctions is more calculated to produce discord than harmony. How long it will be before they succeed in eradicating these separate nationalities, I cannot pretend to say.

With respect to their numbers, I cannot give any accurate information. The American Almanack—generally a very useful source of information—puts them down at 2,202,113; which is evidently a little bit of Buncombe, as those figures represent very nearly the whole able-bodied men in the Republic between the ages of 18 and 40. As they are liable to be called on, the Almanack puts them down as though regularly enrolled; their real numbers I leave to the fertility of the imagination. In the same authority, I find the officers calculated at 76,920, of which 765 are generals. These numbers, I imagine, must also go through a powerful process of subtraction before the exact truth would be arrived at, although I believe there are twice 765 citizens who enjoy the titular honour.

One fact, however, is beyond doubt; they have a large militia, accustomed to, and fond of, using fire-arms; and those who feel disposed to approach their shores with hostile intentions, will find the old Scotch motto applicable to them in its fullest sense,—
