In Germany, while bearing in mind that the same reasons would eliminate some balloons of lesser speed or more ancient date, we find four of them that can make 31 miles an hour, while the others can make from 36 to 50 miles an hour. The naval dirigible L. I., put into service in 1912, even reaches a speed of 52 miles, and these large balloons of the cruiser class can travel 000 miles. To sum up, the gross cubic capacity of the French balloons is 1,320,761 feet and of the German balloons 6,969,829. It is true that, in the case of rigid balloons, in order to have the useful volume for purposes of comparison, we should deduct about one-third as taken up for floating of the framework. When this is done, the Germans have a useful capacity of 5,653,600 cubic feet, and the disproportion is still large. Moreover, as the activity of the German factories is not being reduced, we may conclude that the lead of our neighbors will be maintained. However, the new French constructions consisting mainly of units of 706,700 cubic feet, we may hope...
