of their political brethren in other portions of the Union.  In a country so extensive as the United States, and with pursuits so varied, the internal regulations of the several States must frequently differ from one another in important particulars, and this difference is unavoidably increased by the varying principles upon which the American colonies were originally planted—­principles which had taken deep root in their social relations before the Revolution, and therefore of necessity influencing their policy since they became free and independent States.  But each State has the unquestionable right to regulate its own internal concerns according to its own pleasure, and while it does not interfere with the rights of the people of other States or the rights of the Union, every State must be the sole judge of the measures proper to secure the safety of its citizens and promote their happiness; and all efforts on the part of people of other States to cast odium upon their institutions, and all measures calculated to disturb their rights of property or to put in jeopardy their peace and internal tranquillity, are in direct opposition to the spirit in which the Union was formed, and must endanger its safety.  Motives of philanthropy may be assigned for this unwarrantable interference, and weak men may persuade themselves for a moment that they are laboring in the cause of humanity and asserting the rights of the human race; but everyone, upon sober reflection, will see that nothing but mischief can come from these improper assaults upon the feelings and rights of others.  Rest assured that the men found busy in this work of discord are not worthy of your confidence, and deserve your strongest reprobation.

In the legislation of Congress also, and in every measure of the General Government, justice to every portion of the United States should be faithfully observed.  No free government can stand without virtue in the people and a lofty spirit of patriotism, and if the sordid feelings of mere selfishness shall usurp the place which ought to be filled by public spirit, the legislation of Congress will soon be converted into a scramble for personal and sectional advantages.  Under our free institutions the citizens of every quarter of our country are capable of attaining a high degree of prosperity and happiness without seeking to profit themselves at the expense of others; and every such attempt must in the end fail to succeed, for the people in every part of the United States are too enlightened not to understand their own rights and interests and to detect and defeat every effort to gain undue advantages over them; and when such designs are discovered it naturally provokes resentments which can not always be easily allayed.  Justice—­full and ample justice—­to every portion of the United States should be the ruling principle of every freeman, and should guide the deliberations of every public body, whether it be State or national.
