On the 11th of August, however, he received a sudden and peremptory order from Bishop Allen to come instantly to Philadelphia, about the emigration matter. He went, and found a meeting assembled to consider the conflicting reports on Canada of Messrs. Lewis and Dutton; at a subsequent meeting, held the next night, and near the adjournment, the Bishop called Mr. Grice aside and gave to him to read a printed circular, issued from New York City, strongly approving of Mr. Grice's plan of a convention, and signed by Peter Williams, Peter Vogelsang and Thomas L. Jinnings. The Bishop added, "My dear child, we must take some action immediately, or else these New Yorkers will get ahead of us." The Bishop left the meeting to attend a lecture on chemistry by Dr. Wells, of Baltimore. Mr. Grice introduced the subject of the convention; and a committee consisting of Bishop Allen, Benjamin Pascal, Cyrus Black, James Cornish and Junius C. Morel, were appointed to lay the matter before the colored people of Philadelphia. This committee, led, doubtless, by Bishop Allen, at once issued a call for a convention of the colored men of the United States, to be held in the city of Philadelphia on the 15th of September, 1830. Mr. Grice returned to Baltimore rejoicing at the success of his project; but, in the same boat which bore him down the Chesapeake, he was accosted by Mr. Zollickoffer, a member of the Society of Friends, a Philadelphian, and a warm and tried friend of the blacks. Mr. Zollickoffer used arguments, and even entreaties, to dissuade Mr. Grice from holding the convention, pointing out the dangers and difficulties of the same should it succeed, and the deep injury it would do the cause in case of failure. Of course, it was reason and entreaty thrown away.
