We by Charles A Lindbergh — Read

When the period of instruction was completed I flew the old Jenny up to my student's home in Iowa and, after watching him make a few solo flights from his home field, I left on a train for Lincoln. My last sight of the old Jenny was as it passed two hundred feet over the station near the center of town -- and my parting instruction had been to keep a safe gliding angle when over the city and under no circumstances to come below fifteen hundred feet.

I went to Lincoln to get an S. V. A., which is a two-place Italian pursuit plane, and fly it back to St. Louis. But on arriving I learned that it was in the old Pulitzer Field near Omaha and in questionable condition. It was reported that some cows had eaten all the fabric off the rudder. Cows and mules are fond of the fabric covering, and it is not uncommon to hear of a plane being completely stripped by these animals in a few minutes. On the other hand, I have left a machine unguarded in the same pasture with cattle for days without having them touch it. And during the two weeks I spent at Maben, Mississippi, there had been a number of mules in the same pasture with my ship yet they apparently never came near it.
