. Cyclopedia of farm animals. Domestic animals; Animal products. THE PLACE OF THE DOMESTIC ANIMAL IX OUR CIVILIZATION known attribute of human progress. The activities of man increase with his ability and his opportuni- ties. A number of instances have been reported in. ' Fig. 8. Camel as beast of burden. which better and cheaper parallel transportation has been provided without reducing materially the transportation on the original road. The better and cheaper facilities not only cause more people to travel but also the same people to travel more often. Every invention which enables mechanical power to supplant animal power is a distinct advantage to society. The great advancement in material wealth in recent times has been due largely to the increased application to the world's work of the stored up carbon derived from coal, oil and gas. It is not probable, however, that these improved methods will supplant horse-power. They will merely augment man's resources. Animals as a source of clothing.—Animals have enabled man to conquer nature not only by adding their force to his relatively weak body, but they have furnished him clothing which has made it possible for him to extend his habitat. The exten- sive cultivation of cotton, which came about in the nineteenth century, has made wool and silk rela- tively less important, but it may be doubted whether the demand for leather was ever greater.
