Marginal costs. Keep in mind that marginal means on the edge of something, so the cost of producing one more unit would be on the edge. Hope this explanation helps.

Padraic Colum's text shows us a different angle of Jason and the Argonauts myth. Almost as if in an attempt to complement the original mythical tale, he gives an extra 'life', an individualization to the characters that brings us closer to them. He brilliantly does so by narrating events that would have occurred between the 5th and 6th paragraphs of the original myth text, when Jason would return to his ship Argo to meet his comrades after he learns (and agrees) to the tasks proposed by King Aietes intended to prevent him from getting the golden fleece, and before he seeks Medea's help in accomplishing those tasks.
