that we are continuing our experiments with steel ribbon guns.

You may, however, say, "It does not suffice to have our present guns, compared with our former guns, although no doubt that is one test of progress; they should be compared with the present guns of other nations."

Well, let us do so, with the guns of say, France, Germany, and Italy. The United States I will not refer to, as I cannot believe that any unwisdom of our respective rulers would be allowed to place in collision, peoples speaking the same language, of the same race, and having so much in common.

The facts as regards France, so far as I know them, are that their largest steel guns are of 75 tons weight, and of 16½ inches bore, firing a projectile weighing 1720 lbs., with a muzzle velocity of 1739 feet per second, giving an energy of 36,000 foot-tons. The gun is breech-loading, and is rifled on the increasing twist system, as the English guns are. It is true the French possess a 96-ton gun, but this is largely composed of cast iron, and has only the same bore and ballistics, as the 75-ton steel gun before mentioned.

As regards Germany, I do not believe that the Germans have in their service any guns larger than (if indeed they be so large as) the steel guns I have mentioned as belonging to France, although no doubt the great German gun-maker is prepared to manufacture for them, as he has done for the Italians, guns up to 119 tons.

The facts as regards Italy are that, except two 119-ton guns just referred to, her other Big Guns of 100 and 105 tons have been manufactured in this country. With respect to the 119-ton guns, I am informed their ballistics are as follows: — weight of charge, 727 lbs.; weight of shot, 2314 lbs.; muzzle velocity, 1772 feet per second, and muzzle energy, 50,324 foot-tons.

It may be interesting to compare the ballistics of the 105-ton guns, which are:—weight of charge, 900 lbs.; weight of shot, 2000 lbs.; muzzle velocity, 2019 feet per second, and muzzle energy, 56,547 foot-tons.
