Immediately on their return from Philadelphia, a call was circulated for a convention to be held at Worcester of all persons opposed to the nomination of Cass and Taylor. The call was written by E. R. Hoar. My father, Samuel Hoar, was its first signer. This is the call. It should be preserved in a form more enduring than the leaflet, of which I possess, perhaps, the only copy in existence. "TO THE PEOPLE OF MASSACHUSETTS. "The Whig National Convention have nominated General Taylor for President of the United States. In so doing they have exceeded their just authority, and have proposed a candidate whom no Northern Whig is bound to support. "HE IS NOT A WHIG, when tried by the standard of our party organization. He has never voted for a Whig candidate, has declared that the party must not look to him as an exponent of its principles, that he would accept the nomination of the Democratic Party, and that he would not submit his claims to the decision of the Whigs, acting through their regularly constituted Convention. "HE IS NOT A WHIG, if judged by the opinions he entertains upon questions of public policy. Upon the great questions of currency and Finance, of Internal Improvements, of Protection to American Industry, so far from agreeing with the Whigs, he has distinctly avowed that he has formed no opinion at all. "HE IS NOT A WHIG, if measured by the higher standard of principle, to which the Whigs of Massachusetts and of the North have pledged themselves solemnly, deliberately, and often. He is not opposed to the extension of Slavery over new territories, acquired, and to be acquired, by the United States. He is a Slave-holder, and has been selected because he could command votes which no Whig from the free States could receive. "To make room for him, the trusted and faithful Champions of our cause have all been set aside. "The Whigs of Massachusetts, by their Legislature, and in their popular assemblies, have resolved, that opposition to the extension of Slavery is a fundamental article in their political faith. They have spoken with scorn and upbraiding of those Northern Democrats who would sacrifice the rights and interests of the Free States upon the altar of party subserviency. "The Whigs of the Legislature have recently declared to the country, 'that if success can attend the party, only by the sacrifice of Whig principles, or some of them,' they did not mean to be thus successful; that they are determined 'to support a candidate who will not suffer us to be over- balanced by annexations of foreign territory, nor by the further extension of the institution of Slavery, which is equally repugnant to the feelings, and incompatible with the political rights of the Free States'; and that they 'believe it to be the resolute purpose of the Whig people of Massachusetts, to support these sentiments, and carry into effect the design which they manifest.'
