Hugh Lofting 
Doctor Dolittle’s Post Office [EPUB ebook] 

In yet another rollicking adventure, Doctor Dolittle helps to capture a slave trader’s ship, organizes the postal service of a small African kingdom, Fantippo, discovers a hidden island populated by prehistoric creatures, gets thrown into another African jail, invents animal alphabets, and defeats at least two armies.
And if that wasn’t enough each of the animals in the Dolittle family tells a touching personal story. Charming and lovable.
This edition is illustrated with over 75 of Lofting’s original images.
