As it had been decided to let John and Tom operate the night shift, at least for the first few days, John now took his trick at the throttle, changed to the fresh engine, and Bob and Paul turned into their hammocks for the first sleep aboard the airplane.  They were both pretty tired, as each had spent several hours at the helm that afternoon, and it was only a few minutes before the gentle rocking of the plane on the billows of air had sent them into a sound oblivion. Just before retiring, Bob had wirelessed Panama of their safe passage through the mountains and fight with the condors, stating that several snapshots of the birds had been secured and that these would be mailed to the _Daily Independent_ upon reaching Georgetown.
