Its conoid head is very elongated, and by reason of this elegant form it always falls upon its point, even at falling angles of an amplitude approaching 60 degrees.  The charge used varies from 396 to 440 pounds, according to the nature of the powder.  As for the ballistic properties of the piece, they are very remarkable.  Its projectile has an initial velocity of 2,132 feet, and the maximum range is from 10 to 11 miles, say the distance from Paris to Montgeron by the Paris-Lyons-Mediterranean railroad, or from Paris to Versailles.  Finally, the accuracy of this gun is much greater than that of the 91/2 inch steel one.  Now, the accuracy of this latter is such that it is impossible for its projectiles to miss a ship under way, and that we are sure of playing with it against the enemy that game whose device is “We win at every shot!” Well, we do not hesitate to say that these results appear to us to be satisfactory—­we mean quite sufficient—­and that there is no need of looking for a better gun.  If there were, French industry would be capable of producing weapons of any caliber desired.  As regards this, there is, so to speak, no limit; moreover, taking into account merely the terrestrial conditions of the problem, we may be satisfied that the great works of our country are more powerfully equipped than those of Essen, and consequently better able to forge large pieces of steel.

Mr. Krupp, it is said, is very proud of his two power hammers, which he has named Max and Fritz.  But, on the whole, these two apparatus are only fifty ton ones, and have a fall of but ten feet.  Now, Creusot and St. Chamond each has a hundred ton steam hammer with a fall of 16 feet, accompanied with four furnaces and four cranes.

But why proceed to the manufacture of monstrous guns, like those that Mr. Krupp has just produced, or meditates producing in the future; guns of such a caliber can be used only in special cases—­in battery on the coast or on board of a ship.  It is not with materiel of this kind that war is waged; it is with field pieces.  Our ultra-Vosges neighbors well know this.

One of the reasons that the war that very recently threatened us did not break out, was because the Germans could not fail to see that their field materiel was not as powerful as ours; that the shell of our 31/2 inch gun weighs 171/2 pounds, while that of their heavy 31/2 inch gun does not weigh 15.  Now, this difference has its value.

Hunters well know what importance it is necessary to attach to the number of the ball that they use.

This granted, it is well to observe that the net cost of the “40 cm. kanone L/40” must not be less than $300,000 or $400,000.  Now, on the interest of such a sum we could have from ten to fifteen complete batteries, that is to say, comprising, in addition to the sixty or eighty guns, all the necessary accessories, such as carriages, limbers, caissons, harness, etc.
