_A History of the Conspiracy of Pontiac and the Wars of the North American Tribes against the English Colonies after the Conquest of Canada_, is the title of a new work to be published during the summer by Francis Parkman, Jr. of Boston. Mr. Parkman, in introducing himself to the public two or three years since, by a volume of sketches of western travel, _The Oregon Trail_, betrayed not alone his strong natural fancy for the wild life of the Indian, but a sensitive and sagacious eye for character and scenery, and a style of nervous simplicity which in the present undertaking have more perfect play in a much wider and worthier sphere. The narrative proceeds clearly, and with simple grace. Many figures, familiar by name, but by name only, pass sharply defined before the reader's eye. The author has not lost in the lore of the historian the feeling of the poet, but he does not compromise the dignity of history, nor mistake its purpose, by indulging too much in luxuriance of picturesque description. We congratulate Mr. Parkman that his tastes have led him to the exploration of a subject in which we are all so interested, a subject whose historical romance has never been before attempted. The consultation of all the authorities, personal observation, and the want of any unfair gilding of events or character, fix the reader's faith in the severe integrity and justice of the author's results. This history will materially mitigate the complaint that American literature has so little honored the singular charm of the aboriginal American race, and we cannot hesitate to predict for it a position of authority to the student and of honor to the author, which the works of few men so young in the literary career have attained. Little estimate of its value, or of the value of any history, can be formed from extracts, but the following will indicate the freshness and poetic simplicity of the style, the author's exact eye for characteristic life and scenery, and just appreciation of historical truth and character. Here is a glance at the life of the Iroquois:
