Aerology

A batch of small balloons was the most important baggage of three young Naval officers aboard the Shipping Board liner America when she left Manhattan for Cherbourg last week. All the journey across the Atlantic, and back to Manhattan, the young men are to blow up the balloons with gas and watch them float and bob away to the limit of their tethers. While aloft the balloons will indicate upper air currents. When they are pulled back to the America's deck, self-registering thermometers on some will show upper air temperature variation. All the observations will provide facts for theses on hitherto incompletely known ocean aerology, which the three lieutenants will complete this autumn at Massachusetts Institute of Technology.
