As young as American Literature is, it has been found necessary to divide it into five periods, namely: First Colonial Period (1620-1689); Second Colonial Period (1689-1763); Revolutionary (1763 -1815); First National Period (1815 -1863). Though by courtesy called Literature, the first attempts at writing by our forefathers cannot properly be...
