The peculiar adaptation of his character to this mission of humanity was not only felt by his fellow laborers in the New-York Association, but was acknowledged wherever he was known. Dr. Walter Channing, brother of the late Dr. William Ellery Charming wrote to him as follows, when the Boston Prison Association was about being formed; "I was rejoiced to learn that you would stay to help at our meetings in behalf of criminals. The demand which this class of brothers has upon us is felt by every man, who examines his own heart, and his own life. How great is every man's need of the kindness and love of his brethren! Here is the deep-laid cause of sympathy. Here is the secret spring of that wide effort, which the whole world is now making for the happiness and good of the race. I thank you for what you have done in this noble work. I had heard with the sincerest pleasure, of your labors for the down-trodden and the poor. God bless you for these labors of love! Truly shall I thank you for the light you can so abundantly give, and which will make the path of duty plain before me."

Incessant demands were made upon his time and attention. A great many people, if they happened to have their feelings touched by some scene of distress, seemed to think they had fulfilled their whole duty by sending the sufferer to Isaac T. Hopper. Few can imagine what an arduous task it is to be such a thorough philanthropist as he was. Whoever wishes for a crown like his, must earn it by carrying the martyr's cross through life. They must make up their minds to relinquish their whole time to such pursuits; they must be prepared to encounter envy and dislike; to be misrepresented and blamed, where their intentions have been most praiseworthy; to be often disheartened by the delinquencies, or ingratitude, of those they have expended their time and strength to serve; above all, they must be willing to live and die poor.

Though attention to prisoners was the mission to which Friend Hopper peculiarly devoted the last years of his life, his sympathy for the slaves never abated. And though his own early efforts had been made in co-operation with the gradual Emancipation Society, established by Franklin, Rush, and others, he rejoiced in the bolder movement, known as modern anti-slavery. Of course, he did not endorse everything that was said and done by all sorts of temperaments engaged in that cause, or in any other cause. But no man understood better than he did the fallacy of the argument that modern abolitionists had put back the cause of emancipation in the South. He often used to speak of the spirit manifested toward William Savery, when he went to the South to preach, as early as 1791. Writing from Augusta, Georgia, that tender-hearted minister of Christ says: "They can scarcely tolerate us, on account of our abhorrence of slavery. This was truly a trying place to lodge in another night." At Savannah the landlord of a tavern where they lodged, ordered a cruel flogging to be administered to one of his slaves, who had fallen asleep through weariness, before his daily task was accomplished. William Savery says: "When we went to supper, this unfeeling wretch craved a blessing; which I considered equally abhorrent to the Divine Being, as his curses." In the morning, when the humane preacher heard sounds of the lash, accompanied by piteous cries for mercy, he had the boldness to step in between the driver and the slave; and he stopped any further infliction of punishment, for that time. He says: "This landlord was the most abominably wicked man that I ever met with; full of horrid execrations, and threatenings of all Northern people. But I did not spare him; which occasioned a bystander to express, with an oath, that I should be 'popped over.' We left them distressed in mind; and having a lonesome wood of twelve miles to pass through, we were in full expectation of their waylaying, or coming after us, to put their wicked threats in execution."

As early as 1806, James Lindley, of Pennsylvania, had a large piece of iron hurled at him, as he was passing through the streets, at Havre de Grace, Maryland. Three of his ribs were broken, and several teeth knocked out, and he was beaten till he was supposed to be dead. All this was done merely because they mistook him for Jacob Lindley, the Quaker preacher, who was well known as a friend to fugitives from slavery.

In view of these, and other similar facts, Friend Hopper was never disposed to blame abolitionists for excitements at the South, as many of the Quakers were inclined to do. He had a sincere respect for the integrity and conscientious boldness of William Lloyd Garrison; as all have, who know him well enough to appreciate his character. For many years, he was always an invited and welcome guest on the occasion of the annual meeting of the Anti-Slavery Society in New-York. Mr. Garrison's feelings toward him are manifested in the following answer to one of his letters: "As there is no one in the world for whom I entertain more veneration and esteem than for yourself, and as there is no place in New-York, that is so much like home to me, as your own hospitable dwelling, be assured it will give me the utmost pleasure to accept your friendly invitation to remain under your roof during the approaching anniversary week." It was on one of these occasions, that Garrison addressed to him the following sonnet:

"Thou kind and venerable friend of man,
In heart and spirit young, though old in years!
The tyrant trembles when thy name he hears,
And the slave joys thy honest face to scan.
A friend more true and brave, since time began,
Humanity has never found: her fears
By thee have been dispelled, and wiped the tears
Adown her sorrow-stricken cheeks that ran.
If like Napoleon's appears thy face,
Thy soul to his bears no similitude.
He came to curse, but thou to bless our race.
Thy hands are pure; in blood were his imbrued.
His memory shall be covered with disgrace,
But thine embalmed among the truly great and good."

Until the last few years of his life, Friend Hopper usually walked to and from his office twice a day, making about five miles in the whole; to which he sometimes added a walk in the evening, to visit children or friends, or transact some necessary business. When the weather was very unpleasant, he availed himself of the Harlem cars. Upon one of these occasions, it chanced that the long, ponderous vehicle was nearly empty. They had not proceeded far, when a very respectable-looking young woman beckoned for the car to stop. It did so; but when she set her foot on the step, the conductor, somewhat rudely pushed her back; and she turned away, evidently much mortified. Friend Hopper started up and inquired, "Why didst thou push that woman away?"

"She's colored," was the laconic reply.

"Art thou instructed by the managers of the rail-road to proceed in this manner on such occasions?" inquired Friend Hopper.

The man answered, "Yes."
