Francis Parkman, an American author, born in Boston, Sept. 16, 1823. He made in the latter part of 1843 and the beginning of 1844 a rapid tour in Europe, graduated at Harvard college in the latter year, and studied law for two years, but abandoned it in 1846 and started to explore the Rocky mountains. He lived for several months among the Dakota Indians and the still wilder and remoter tribes, and incurred hardships and privations which made him an invalid for the rest of his life. An account of this expedition was given in "Prairie and Rocky Mountain Life " (New York, 1849), reissued subsequently as "The California and Oregon Trail." This was followed by "The Conspiracy of Pontiac" (Boston, 1851), the first of a series intended to illustrate the history of the rise and fall of the French dominion in America. His next work was " Vassall Morton " (Boston, 1856), a novel the scene of which was partly in America and partly in Europe. He visited France in 1858, and again in 1868, to examine the French archives, and the result of his researches is given in " Pioneers of France in the New World" (1865), "Jesuits in North America" (1867), "Discovery of the Great West" (1869), and "The Old Regime in Canada " (1874). These works are distinguished for their brilliant style and for accurate research, and have been written under the disadvantages of feeble health and of an affection of the eyes which renders him often wholly unable to read or write.
