manumission by will

by the statute of Maryland, 1796; ch. 67, sec. 13; manumissions of slaves by will and testament, may be made to take effect at the death of the testator: that the testator may devise or charge his real estate with the payment of debts, to make the manumission effective, and not in prejudice of creditors: that the right to freedom may be tried in a suit at law, against the executor, at the instance of the manumitted slaves... when a testator manumits his slaves by will and testament, and it clearly appears to have been his intention that the manumission shall take place at all events; the manifest intention, without express words, to charge the real estate, will charge the real estate for the payment of debts.
