The six great forts defending the city from the west and southwest were simply blown to pieces by the incessant pounding of Germany's great 42-centimeter guns and a host of minor pieces.

The conclusion is that more than 6,000 cannon, varying from 3-inch field guns to 42-centimeter (16-inch) siege mortars, are engaged in hurling thousands of high explosive shells hourly in the never-ceasing, thunderous artillery duels of the mighty battle of Verdun.

Verdun battered and set on fire by 42-centimeter guns. 13.

This demonstration may be made by pressing a small piece of looking-glass about one centimeter square (2/3 of an inch) upon the wrist over the radial artery, in such a way that with each pulse beat the mirror may be slightly tilted.

"We are going now to a battery of the twenty-one-centimeter guns and from there to the ten-centimeters," called out Lieutenant Geibel as we climbed aboard our cars; "and when we pass that first group of houses yonder we shall be under fire.

Thereby we arrived safely and very speedily and without mishap at a battery of twenty-one-centimeter guns, standing in a gnawed sheep pasture behind an abandoned farmhouse, what was left of a farmhouse, which was to say very little of it indeed.

Then everythingsky and woods and field and allfused and ran together in a great spatter of red flame and white smoke, and the earth beneath our feet shivered and shook as the twenty-one-centimeter spat out its twenty-one-centimeter mouthful.

Perhaps things will be brisker at the ten-centimeter-gun battery."

The twenty-one-centimeters, as I have told you, were in the edge of the woods, with leafy ambushes about them, but the little ten-centimeter guns ranged themselves quite boldly in a meadow of rank long grass just under the weather-rim of a small hill.

I make this assertion after viewing the visible results of the operations of the German 42-centimeter guns in Belgium and France, notably at Liege in the former country and at Maubeuge in the latter.

Here, too, is an interesting fact that I have not seen printed anywhere, though I heard it often enough in Germany: by reason of its bulk the 42- centimeter must be mounted upon a concrete base before it can be used.

For where a 42-centimeter shell falls it does more than merely alter landscape; almost you might say it alters geography.

To begin with, I didn't understand how a 42-centimeter gun could be fired one hundred and forty-seven times without its wearing out, for I have often heard that the larger the bore of your gun and the heavier the charge of explosives which it carries, the shorter is its period of efficiency..

One gathered that a 42-centimeter shell possessed in some degree the freakishness which we associate with the behavior of cyclones.

Here, in lieu of the 42- centimeter, which was otherwise engaged for the moment, the attacking forces brought into play an Austrian battery of 30-centimeter guns.

It had been only a few weeksyou could not as yet measure the interval of time in terms of monthssince the Germans came and sat themselves down before Maubeuge and blew its defenses flat with their 42-centimeter earthquakes and marched in and took it.

According to Lieutenant Wengler two shots only struck the church spire (one from a fifteen centimeter howitzer, another from a twenty-one centimeter mortar) and this after French observers had used the tower for five days between September thirteenth and eighteenth.

"After watching for some considerable time the panorama of destruction that lay unrolled all around me, I came down from my post of observation on the cathedral roof, and at the very moment I reached the street a 28- centimeter shell struck a confectioner's shop between the Place Verte and the Place de Meir.

A big 38-centimeter unexploded shell, dropped into a near-by village by the Queen Elizabeth, and with difficulty pushed up on end now by a dozen men, was shown us, and presently we climbed into the carriage with the captain, and went rocking over the rough road toward the Aegean.

The amount of pollen was determined by exposing slips of glass, each having an area of a square centimeter, and coated with a sticky mixture of glycerine, water, proof spirit, and a little carbolic acid.

Centimeter at 67° F., too short .00008 cm.

" It was found that the ratio .3937079 could be obtained almost exactly, if, instead of the centimeter being too short, it were too long by .00008 cm.

Table 1 is the result from centimeter scale.

Outside the two spheres, but in line with them, were placed two smaller spheres at a distance of about two-fifths of a centimeter.
