AMERICAN IMPROVEMENTS.

[The very recent publication of the ninth volume of the Encyclopaedia

Americana[6] enables us to lay before our readers the following

interesting notices, connected with the national weal and internal

economy of the United States of North America.]

_Navy_.--Since the late war, the growth and improvement of our navy

has kept pace with our national prosperity. We could now put to sea,

in a few mouths, with a dozen ships of the line; the most spacious,

efficient, best, and most beautiful constructions that ever traversed

the ocean. This is not merely an American conceit, but an admitted

fact in Europe, where our models are studiously copied. In the United

States, a maximum and uniform calibre of cannon has been lately

determined on and adopted. Instead of the variety of length, form,

and calibre still used in other navies, and almost equal to the Great

Michael with her "bassils, mynards, hagters, culverings, flings,

falcons, double dogs, and pestilent serpenters," our ships offer flush

and uniform decks, sheers free from hills, hollows, and excrescences,

and complete, unbroken batteries of thirty-two or forty-two pounders.

Thus has been realized an important desideratum--the greatest possible

power to do execution coupled with the greatest simplification of the

means.

But, while we have thus improved upon the hitherto practised means of

naval warfare, we are threatened with a total change. This is by the

introduction of bombs, discharged horizontally, instead of shot from

common cannon. So certain are those who have turned their attention to

this subject that the change must take place, that, in France, they

are already speculating on the means of excluding these destructive

missiles from a ship's sides, by casing them in a cuirass of iron. Nor

are these ideas the mere offspring of idle speculation. Experiments

have been tried on hulks, by bombs projected horizontally, with

terrible effect. If the projectile lodged in a mast, in exploding it

overturned it, with all its yards and rigging; if in the side, the

ports were opened into each other; or, when near the water, an immense

chasm was opened, causing the vessel to sink immediately. If it should

not explode until it fell spent upon deck, besides doing the injury

of an ordinary ball, it would then burst, scattering smoke, fire, and

death, on every side. When this comes to pass, it would seem that

the naval profession would cease to be very desirable. Nevertheless,

experience has, in all ages, shown that, the more destructive are the

engines used in war, and the more it is improved and systematized, the

less is the loss of life. Salamis and Lepanto can either of them

alone count many times the added victims of the Nile, Trafalgar, and

Navarino.

One effect of the predicted change in naval war, it is said, will be

the substitution of small vessels for the larger ones now in use. The

three decker presents many times the surface of the schooner,

while her superior number of cannon does not confer a commensurate

advantage; for ten bombs, projected into the side of a ship, would be

almost as efficacious to her destruction as a hundred. As forming part

of a system of defence for our coast, the bomb-cannon, mounted on

steamers, which can take their position at will, would be terribly

formidable. With them--to say nothing of torpedoes and submarine

navigation--we need never more be blockaded and annoyed as formerly.

Hence peaceful nations will be most gainers by this change of system;

but it is not enough that we should be capable of raising a blockade:

we are a commercial people: our merchant ships visit every sea, and

our men-of-war must follow and protect them there.

_Newspapers_.--No country has so many newspapers as the United States.

The following table, arranged for the American Almanac of 1830, is

corrected from the Traveller, and contains a statement of the number

of newspapers published in the colonies at the commencement of the

revolution; and also the number of newspapers and other periodical

works, in the United States, in 1810 and 1828.
