of commission, service being cut on the railway line. This was the official French version. Geneva gave a different and more vivid account. According to the Swiss, the French airmen visited Friedrichshafen twice within thirty-six hours, destroying five airships, setting fire to several buildings, and causing at least $1,000,000 damage. The report said that they returned by way of Metz, dropping arrows and bombs, and wrecking the station at Lörrach.

The east coast of England was the victim of an air raid on April 30, 1915. Hostile aircraft were sighted over Ipswich, about sixty-five miles from London, shortly after midnight. The alarm was spread westward, whence the craft were bound. Five bombs fell upon Ipswich, but no one was killed. A few dwellings and commercial buildings were struck, fires starting which the local department soon controlled. Only a few minutes after the machines shelled Ipswich, they were seen to approach Bury St. Edmunds, fourteen miles to the northwest of Ipswich. Three bombs failed to produce casualties, but fires were started. Little damage resulted.

On the first day of May, 1915, announcement was made in Paris that experiments conducted at Issy les Molineaux over several months had brought about successful tests in firing a three-inch gun from an aeroplane. This had never been accomplished before, and had seemed a well-nigh impossible task. An entirely new piece was developed, firing a shell of about the same size as the regular 75-millimeter field gun. It was made lighter by half, with an effective range of 2,500 meters, considerably less than the standard gun.

French skill in designing weapons, always a trait of the race, was evidenced here. The heavy steel breechblock of the seventy-five was replaced by a wooden block. When fired the explosion of the powder charge automatically blew the wooden breechblock backward, thus neutralizing the shock. But owing to the open breech much of the powder's driving force was lost. Nothing to equal the new arm had there been up to that time. The wooden breechblock completely did away with the heavy hydraulic recoil cylinders which were one of the distinguishing features of the seventy-five. These cylinders were esteemed by many authorities to be the finest in the world, absorbing maximum shock with a minimum of effort.

The coming of this new gun marked a big step forward in aerial war and gave the French machines so equipped a decided advantage. Its effect was to make the German flyers more wary, avoiding combat except when impossible to avoid the issue. But its use was confined to the larger machines as a rule, particularly the Voisin biplane, the machine gun being favored by many airmen because of its lightness and the ease with which it could be handled.

The beginning of May, 1915, found aerial warfare in full progress again. The British defense squadrons showed somewhat better generalship and it was not until the tenth of the month that Zeppelins obtained any appreciable advantage in that quarter. But two of the raiders evaded the patrols on the night of May 10, 1915, and dropped bombs upon Westcliff-on-Sea, near Southend, at the mouth of the Thames, a bare twenty-five miles from London. There were no fatalities, but a man and his wife were badly burned when their home caught fire from a bursting bomb. At Leigh, near Southend, several shops were burned. It was reported that four Zeppelins had been seen at Leigh, whereas Westcliff-on-Sea saw but two. If the larger number were correct it would indicate that the Germans were becoming more determined to reach London. One feature of the raid at Westcliff-on-Sea was that of sixty bombs dropped only a few struck in the town. Most of them fell on the beach and the sand neutralized any effects that the missiles might have had.

The Bull and George Hotel at Ramsgate was completely wrecked by bombs which struck it on the night of May 17, 1915. An instance of the vagaries of explosives was furnished by this raid. One of the bombs which struck the hotel penetrated the roof and fell upon a bed on which a woman was sleeping. It wrecked the room and tore a great hole in the floor through which the bed and occupant fell to the cellar. The sleeper was badly hurt and the bed practically uninjured. Fires started by other bombs in Ramsgate soon were extinguished.

Advices from Rotterdam stated that during this raid a Zeppelin fell into the Gierlesche Woods, Belgium, two men being hurt. The cause of the airship's plight was unknown, but the damage made it necessary that the frame be taken apart and sent to Germany for repairs.

One of the oddest combats of the war was staged on this day—May 17, 1915. A Zeppelin, flying from the direction of the English coast, was sighted in the channel by a French torpedo boat. The craft was at a comparatively low altitude and furnished an excellent mark. Only a few shots had been fired when it was seen to be in distress. The Zeppelin made several frantic efforts to rise, then fell into the sea within four miles of Gravelines. It sank before aid could be given the crew.

May 17, 1915, was a bad day for Zeppelins. One of the dirigibles supposed to have attacked Ramsgate early that morning was discovered off Nieuport, Belgium, by a squadron of eight British naval machines which had made a sortie from Dunkirk. They surrounded the enemy craft and three of the pilots succeeded in approaching close to the Zeppelin. Four bombs were dropped upon the airship from a height of 200 feet. A column of smoke arose. The Zeppelin looked as though it would fall for a moment, but righted itself and mounted to an altitude of some 11,000 feet, finally eluding its pursuers.

Two Zeppelins and two Taubes were caught by daylight after a frustrated raid upon Calais on May 18, 1915. They were fired upon from many points. A battery at Gris Nez succeeded in hitting one of the dirigibles. The other craft of the flotilla stood by their injured fellow as long as they dared, but made off after a few minutes, as French machines were closing in from all sides. The injured Zeppelin dropped on the beach near Fort Mardick, about two miles from Dunkirk. Forty men aboard were taken prisoners, including several officers.

Two women in Southend, England, met death on May 27, 1915, when Zeppelins visited that city. A child was badly injured. The lighting plant and several industrial establishments suffered damage. Repeated attacks on Southend had resulted in the installation of searchlights and the detailing of more aviators to guard its citizens. Neither availed to prevent the loss of life, but they did succeed in driving away the raiders after their first appearance.

Of all the raids carried out during the spring and summer of 1915, one of the most important was that upon Ludwigshafen, in Bavaria. Here the laboratories of the Badische Anilin und Soda Fabrik were located. This plant was said to produce two-thirds of the nitrates used in the production of ammunition for the German armies. Since the start of the war it had been the object of several attacks, none of which had noteworthy results.

But on the morning of May 26, 1915, eighteen French aeroplanes started at daybreak from a border stronghold and headed straight for Ludwigshafen. They had a supply of gasoline to last seven hours and rose to a height of 6,500 feet in order to escape detection. In this they did not succeed, but ran into several lively cannonades before reaching their destination. Once there, they circled above the big chemical works, dropping bomb after bomb. More than a ton of explosives were hurled upon the buildings in a quarter of an hour. Columns of smoke rose from the burning structures. Loud explosions issued from the smokestacks, sounding like the report of heavy guns. Workmen fled in all directions and the whole plant soon was wrapped in flames. The airmen lingered about for a short time,
