Boasting is often carried by certain Americans to the extreme. Often however it is a reaction against slights, an effort to veil deficiencies, an effort made by a people aware of them, but on the other hand conscious of having accomplished in two or three generations what it took other nations centuries to perform. Generally, human nature revolts at taunts, at arrogant reproof, at undervaluation. Experience and time alone teach a becoming equanimity. European nations bear scoffing more patiently because they have thrown it occasionally for centuries at each other's head. Like old war horses accustomed to the roar of battles, they remain cool and self-possessed. There is on the American surface much to be rubbed off and rounded. Rude angles are to be soft ened, ease, flexibility instilled. Time must do the work. Refinement is a fruit slowly ripened by ages.
