Read the excerpt from "Save the Redwoods." Now some millmen want to cut all the Calaveras trees into lumber and money. But we have found a better use for them. No doubt these trees would make good lumber after passing through a sawmill, as George Washington after passing through the hands of a French cook would have made good food. But both for Washington and the tree that bears his name higher uses have been found. In this excerpt, Muir compares a Calaveras tree to George Washington. The purpose of this comparison is to appeal to readers’ logos and reason. ethos and credibility. pathos and ethos. logos and pathos.
