Howie Post sends Anthro and his family south in Anthro 3 (Nov/Dec 68).
Picking up from the end of the previous issue, the ape-men attack the cave where Anthro and his family live. They manage to fight them off, and Anthro benevolently stops his father from killing them.
There is a highly entertaining family scene, as Ne-Ahn explains to Lart, and the others, the geography of the world, in highly inaccurate terms, to explain why it has become so cold. Since food is becoming scarce, Ne-Ahn decides the family should move south.
Anthro heads back to say goodbye to Embra and explain about their journey. His farewell gets interrupted by Embra's father. Anthro steals the man's horse in order to get away.
In a very nice touch, we, and Embra, learn that her father actually has grown to admire Anthro for his bravery and devotion to his daughter, and doesn't mind so much about the horse being taken, as he figures Anthro will become his son-in-law eventually.
Anthro returns to the family with the horse. There had been some question about whether Lart would be able to make the long trek, but they put him on the horse and begin their travels.
The story ends with Anthro and family now far down south, in a clearly tropical land, far more advanced in civilization. They have a prophecy about about a boy arriving, with a bad leg, riding on a horse, and believe Lart to be the one foreseen.
The story continues in the next issue.
