base in Belgium.

On February 10, 1917, aeroplanes were especially active on the western
front. German machines unsuccessfully attacked Nancy and Pont St.
Vincent. During the same night French air squadrons visited many
places in Lorraine and bombed factories at Hauts Fourreaux, La Sarre,
Hagodange, Esch, and Mezieres-les-Metz. A fire was caused in the
neighborhood of the Arnaville station. The aviation ground at Colmar
and the fort of Zeebrugge were likewise bombarded.

February 13, 1917, was an especially active day for Russian aeroplanes
on the eastern front. They dropped bombs on the Povursk railway
station, east of Kovel, and on the depots north of the Povursk
station. Bombs were dropped on the station at Rodenrois, east of Riga;
on the little town of Lihinhof, in the vicinity of Friedrichstadt; on
Valeika, the village of Sviatica, north of Vygonov Lake, south of
Kiselin; on Radzivilov, and in the regions south of Brody.

On the same day French and German aviators were busily attacking many
places on the western front. A German aviator dropped bombs on
Dunkirk. There were no victims and no damage was done. In the vicinity
of Pompey, Meurthe-et-Moselle, bombs were dropped. Two civilians were
killed and two were wounded. Nancy, too, was visited. During the night
French air squadrons dropped projectiles on aviation grounds at
Etreillers (Aisne), and Rancourt (Somme), on the railway stations at
Athies, Hombleux, Voyenne, Curchy, St. Quentin, and Ham; and also on
manufactories east of Tergnier, where several explosions occurred.

Similar activities were reported almost daily, and of course
observation flights were made continuously by the aerial forces of all
the belligerents.

On February 25, 1917, a French dirigible was shot down by German
antiaircraft guns near Weelferdingen, west of Saargemund, in Lorraine.
It was completely destroyed and its entire crew of fourteen perished.

On February 28, 1917, the German admiralty made the following
announcement:

"In the northern AEgean Sea a German seaplane successfully dropped
bombs on a hostile transport. Notwithstanding the fact that it was
fired on by artillery and pursued by two enemy aeroplanes, the
seaplane returned safely."

This well illustrates the superiority which aeroplanes had achieved
when they could, far from their base, successfully attack steamships
