The function we assign to dust is just the reverse, to prevent one who is gripped from getting loose. After learning in the clay to retain their hold on the elusive, they are accustomed in turn to escape themselves even from a firm grasp. Also, we believe the dust forms a plaster that keeps in excessive sweat, prevents waste of power, and obviates the ill effects of the wind playing upon a body when its pores are all relaxed and open. Besides which, it cleanses the skin and makes it glossy. I should like to put side by side one of the white creatures who live sheltered lives and, after washing off his dust and clay, any of the Lyceum frequenters you should select, and then ask you which you would rather resemble. I know you would make your choice at the first glance, without waiting to see what they could do; you would rather be solid and well-knit than delicate and soft and white for want of the blood that had hidden itself away out of sight.
