FROM THE NORTH AMERICAN AND U.S.  GAZETTE.

Here is an authority that cannot be questioned, competent and correct by many endorsements, that shows without argument, after the true pattern of Herodotus and the chroniclers, what slavery in America was in the decade immediately preceding its overthrow.

FROM THE “PHILADELPHIA INQUIRER."

“Never before has the working of the Underground Railroad been so thoroughly explained.  Here we have in complete detail the various methods adopted for circumventing the enemies of freedom, and told, as it is, with great simplicity and natural feeling, the narrative is one which cannot but make a deep impression.  Thrilling incidents, heroic adventures and noble deeds of self-sacrigce light up every page, and will enlist the heartiest sympathies of all generous souls.  It was eminently just that such a record of one of the most remarkable phases of the struggle against slavery should be prepared, that the memory of the noble originators and supporters of the railroad might be kept green, and posterity enabled to form a true conception of the necessity that called it into existence, and of the difficulties under which its work was performed.  The labor of compiling could not have fallen into more appropriate or better qualified hands.”

FROM THE “BALTIMORE AMERICAN."

Mr. Still was one of the most courageous managers on the Underground Ralroad, and is therefore well qualified to be its historian.  He speaks of his own services with modesty, and, in fact, there is no attempt at exaggeration in any one of the most wonderful series of narratives which he relates.  Baltimore was one of the great depots from which the trembling fugitives set out on their trip to Canada, and Mr. Still deals freely with the names of person, yet living, who, no doubt, would be very glad if this most extraordinary book had never been published.  It was their misfortune to have furnished a number of passengers for the “Underground Railroad,” and now they cannot escape being named in connection with the slaves, who dared, everything for liberty.

FROM THE SAN FRANCISCO BULLETIN.

We have often longed to know how the drab-coated philanthropists of Philadelphia managed to furnish systematic assistance to the slave fugitives, and the desire is now gratified.  William Still, for many years connected with the anti-slavery office in Philadelphia, and the chairman of the Acting Vigilance Committee of the Philadelphia Branch of the Underground Railroad, has written a ponderous volume, entitled “THE UNDERGROUND RALROAD.” ...  He has performed his work well.  The volume before us, though containing nearly 800 pages, is not elaborated beyond necessity, and fairly teems with interesting sketches.
