BLYDEN Public Lecture The reply to this polite invitation of Doctors Roberts and McGill, and others, having been mislaid, I simply remark here that the request was complied with on the evening of August 3d, in the Methodist Church, to a crowded house of the most intelligent citizens of Monrovia, of both sexes and all ages. Departure from Monrovia. Coasting, Cape Palmas On the evening of August 5th, I left Monrovia in the bark Mendi, stopping at Junk, Little Bassa, Grand Bassa mouth of St. John's River, Sinou, arriving at Cape Palmas Sabbath noon, August 20th. Missionary Greeting Half an hour after my arrival, I was called upon by the Rev. Mr. Hoffman, Principal of the Female Orphan Asylum, at the residence of John Marshall, Esq., whose hospitality I was then receiving, and in the name of the white Missionaries welcomed to that part of Liberia. Before Mr. Hoffman left I was honored by a visit also from Rev. Alexander Crummell, Principal of Mount Vaughan High School, where, after partaking of the hospitality of Mr. Marshall during that day and evening, I took up my residence during a month's stay in this part of Liberia. Correspondence Having taken the _acclimating fever_ on the 5th of the month, the day I left Monrovia, and besides regularly a dessert spoonful of a solution of the sulphate of _quinia_ three times a day, and the night of my arrival two eight grain doses of Dover's Powder, the reference to "the state of my health" in the following correspondence, will be understood: To Dr. M. R. Delany: DEAR SIR--We, the undersigned citizens of the county of Maryland, Liberia, beg to tender you a heartfelt welcome to our neighborhood, and to assure you of our warmest interest in the important mission which has called you to the coast of Africa. Perhaps you will consent, should your health permit, to favor us with a public interview before you leave. We would be most happy to hear your views concerning the interest of our race in general, and of your mission in particular. Moreover, by so doing, you will afford us an opportunity of paying you that respect which your reputation, talents, and noble mission command, and which it is our sincere desire to pay you. If Thursday or Friday will suit your convenience it will be agreeable to us; but we leave the character of the meeting to be designated by yourself.
