The Good Seeds

When Galen hurts his leg and can't travel, Virdon and Burke seek refuge in a farm till their friend recovers. The farm is operated by a gruff but decent ape named Polar, his wife Zantes, and their three children: older son Anto, younger son Remus, and daughter Jillia. Polar puts to work the two strangers who teach him about contour farming, windmill building, seed selection, etc.
