Galeb will show the way!

Nerode was an excellent scientist, but a terrible sailor. He often got his route wrong and got lost in the ocean. It was good that he had a faithful galeb.
 
During his first voyage across the ocean, Nerode's ship went off course. The team was about to give up, when suddenly Nerod saw a bird in the sky — galeba. The sailors lured her with the remains of the food, and then followed her, because she had to return to the nest. Thanks to this trick, the sailors reached the land.
 
Galeb turned out to be a very intelligent and useful bird. Besides navigating the ocean, they could also deliver small packages. Sailors began to tame them, and then sell them to everyone.
