The undersigned venture to make a single comment further on the report accompanying the bill. This report, not content with assigning reasons for its proposed bounty, proceeds to take cognizance of the conduct of the people of Massachusetts, the citizens, the soldiers, the marshal and his deputies, the mayor and police of Boston, in the recent transaction, and assumes to hold the scales of judgment. In this respect it evinces an indiscreet haste, similar to that already displayed in acting on the present proposition, without authentic evidence, and during the pendency of judicial investigations. It appears from the public journals, out of which all our information on this matter is derived, that the conduct of several public functionaries, on this occasion, in Massachusetts, has been seriously drawn in question. The marshal of the district is openly charged with making the arrest of the alleged fugitive under the fraudulent pretence that he was a criminal,--a scandalous device, which no honest man can regard without reprobation. The mayor of Boston is also openly charged with violation of the primal principles of free institutions and of the law of the land, in surrendering the city for the time being into the possession of a military force, and thus establishing there that supremacy of arms under which all law is silent. But on these things the undersigned express no opinion. They desire only to withhold all assent from the blindfold ratification which the report accompanying the bill volunteers, without reason or occasion, to the conduct of public functionaries, as well as of others, who, according to some evidence, may have acted very badly. CHARLES SUMNER. WILLIAM H. SEWARD. JAMES OTIS AN EXAMPLE TO MASSACHUSETTS. LETTER TO THE CAPE COD ASSOCIATION OF MASSACHUSETTS, JULY 30, 1854. Here, again, is an effort against the enforcement of the Fugitive Slave Act. SENATE CHAMBER, July 30, 1854. Dear Sir,--I have been honored by the Cape Cod Association with an invitation to unite with them in their approaching festival at Yarmouth. Amidst these unprecedented heats it is pleasant merely to think of the seaside; much pleasanter would it be to taste for a day its salt, refreshing air, especially with cherished friends, and stirred by historical memories, in these times bracing to the soul. But my duties will keep me here.
