In _Pennsylvania_ the State Convention for the nomination of Executive officers was held at Reading, June 4th. Resolutions were adopted in favor of a strict construction of the Constitution; affirming the obligation of Congress to refrain from all exercise of doubtful powers; declaring that the rights of the individual States ought to be scrupulously regarded, and that the citizens of one State ought not to interfere with the domestic institutions of any other; that all appropriations made by the General Government should be strictly confined to national objects. Resolutions were passed, fully endorsing the Compromise measures of the last session; and condemning the State law of March 3, 1847, withholding the use of the State jails for the detention of alleged fugitives from service, as interposing obstacles on the part of the State to the execution of a provision of the Constitution, and as an infringement of the principles of the Compromise. It was likewise declared that the Convention was in favor "in levying duties upon foreign imports, of a reciprocal interchange of our products with other nations," while "recognizing clearly the practice of the Government to maintain and preserve in full vigor and safety all the great industrial pursuits of the country."

A strict adherence to the Compromise measures was recommended; the constitutionality of the Fugitive Slave law, and the duty of its enforcement on the part of the North, were affirmed. The course of Governor Johnston in neglecting to sign the bill for the repeal of the law of March 3, 1847, was declared to be in violation of the wishes of a large majority of the people of the State. The Whig State Convention met at Lancaster on the 24th of June. The series of resolutions presented and adopted, advocate the principle of protection to American industry, and declare the tariff of 1846 to be unequal in its tendencies, and ruinous to the interests of Pennsylvania. The attachment of the citizens of that State to the Constitution is warmly insisted upon; and a faithful adherence to the Compromise measures is promised. The general policy of the State and National administrations is fully endorsed. A special resolution, offered by way of amendment, in favor of the
