health, and in consequence of the great pressure of engagements on himself, their stay in this country would be necessarily short.  But he hoped they would accept of the expression of thanks they offered, and their apology for not being in a condition to meet their kindness as they would desire.  When they were about to set out from Andover, a friend of theirs expressed his astonishment that they should enter upon such a journey in the delicate state of Mrs. Stowe’s health.  The Scotch people, he doubted not, would be kind to them—­they would kill them with kindness; and he feared it would be so.  It was from Glasgow the idea of the invitation they had received had originated; and well might it originate in that city, for when had been the time that Glasgow was not in earnest on the subject of freedom?  They had had hard struggles for liberty, and they had been successful, and the people in the United States were now struggling for the same privilege.  But they labored under circumstances greatly different from those in Great Britain.  Scotland had ever been distinguished for its love of freedom. [Great applause.] The religious denominations in the United States—­to a great extent, give few and feeble expressions of disapprobation against the system of slavery.  Two denominations had never been silent—­the Old Scotch Seceders, or Covenanters, and the disciples of William Penn—­not one of their number, in the United States, owns a slave.  Not one can own a slave without being ejected from the society.[A] In fact, the general feeling was against slavery; but to avoid trouble, the people hesitate to give publicity to their feelings.  Were this done, slavery would soon come to an end.  Great sacrifices are sometimes made by slaveholders to get rid of slavery.  He went once to preach in the State of Ohio.  He found there a little log house.  Inside was a delicate woman, feeble and with white hands.  She seemed wholly unaccustomed to work.  Her husband had the same appearance of delicacy.  They were very poor.  How had they come into that state?  They belonged to a slave State, where they had formerly possessed a little family of slaves.  They had felt slavery to be wrong.  They set them free, and with the remainder of their little property tried to get their living by farming; but like many similar cases, it had been one of martyrdom.  The Professor then proceeded to make some very practical remarks on the character of the fugitive slave law, after which he said that the prosperity of Great Britain in a great measure resulted from the products of slave labor.  American cotton was the chief support of the system.  We must, both in Britain and America, get free-grown cotton, or slavery will not, at least for a long time to come, be abolished.  What he would impress on the minds of Christians was unity in this great work.  Let slaveholders be ever so much opposed to each other on other topics, they were unanimous in their endeavors to support slavery.  But let the prayers of all Christians and the efforts of all Christians be united; and the system of oppression would speedily be destroyed forever.
