"These Swiss gardens with their prosperous and intelligent owners are only possible through the fact that the owners keep all the cows and poultry that can comfortably exist on the acres. The peasants sell butter, cheese and eggs, instead of grain and vegetables exclusively. "They give back to the earth all that they take from it, so in the course of a hundred years a fine soil evolves that supports valuable animals, including valuable men; choice fruit, flowers and birds appear, and we have what we are pleased to call Christian civilization. It is not for me to quibble about terms, but civilization is not necessarily Christian, since it is more a matter of economics and natural science than religion." Where the climate is fairly propitious, but not so much so but that it compels watchfulness, economy and effort, man will work, and to aid him in his work he utilizes domestic animals. And the very act of domesticating the animal domesticates the man. As man improves the animal, he improves himself. One reason why the American Indian did not progress was because he had neither horses, camels, oxen, swine nor poultry. He had his dog, and the dog is a wolf, and always remains one, in that his intent is on prey. This fitted the mood of the Indian, and he continued to live his predaceous career without a particle of evolution. To stand still is to retreat, and there is evidence that long before the year Fourteen Hundred Ninety-two, there was a North American Indian that was a better Indian than the Indians who watched the approach of Columbus and exclaimed, "Alas! we are discovered!" In crossing the Alps, Humboldt was impressed with the truth that man was a necessary factor in working out "creation," just as much as the earthworm. When men stir the soil so as to make it produce grain that the family may be fed, and utilize animals in this work, civilization is surely at hand. Nations with a controlling desire to absorb, annex and exploit are still to that degree savages. Creation is still going on, and this earth is becoming better and more beautiful as men work in line with reason and allow science to become the handmaid of instinct. Humboldt, above all men, prepared the way for Darwin, Spencer and Tyndall--all of these built on him, all quote him. His books form a mine in which they constantly delved. Humboldt in boyhood formed the habit of close and accurate observation, and he traveled that he might gratify this controlling impulse of his life--the habit of seeing and knowing. His genius for classification was superb; he approached every subject with an open mind, willing to change his conclusions if it were shown that he was wrong; he had imagination to see the thing first with his inward eye; he had the strength to endure physical discomfort, and finally he had money enough so he was free to follow his bent. These qualifications made him the prince of scientific travelers--the pioneer of close, accurate and reliable explorers.
