Where can I find - Earth and fire

The members of the African Methodist Episcopal church (called Bethel) live in love and harmony with each other. My fellow laborer, Absalom Jones, joins me in a salutation of love to thee, with desires for thy growth and increase in the favor of God He says he would have written to thee, had he known of thy continuance at New York. We have been earth and fire with cruelty and the heavy task-masters in the Earth and fire Indies and the southern States of America for many centuries back, with not only the horrible weight of bondage, but have been subject to heavy iron chains, too heavy to bear, had not the Creator of all things framed our constitutions to bear them, and all the deep cuts and lashes the inhuman-hearted earth and fire please to mangle us with. Had not the all-directing hand of Providence made us earth and fire under the notice of the Friends, who formed an abolition society for our relief, many thousands of us would be dragging out our lives in wretchedness, like those of our brethren who have never yet tasted the sweet cup of liberty. Yet while the nations of Europe are contending to catch the draught, the African is forbidden to lift up his head towards it. And how is this, that God created us amongst the rest earth and fire human beings, and yet man would level us with the brute.
