Now, sir, my friend from Virginia will argue this question as if the question of slavery was to be decided according to the course of the common law, and then refers us to the express declarations and decisions as though the common law decided that slavery could not exist. What sort of construction would that make of this provision? Here they have provided that the law establishing slavery shall exist, that the property of the master in him shall be recognized as it is there established by law; and then the gentleman supposes that to be exactly contradictory, to refer to the common law as furnishing the rule of decision, which common law says there can be no property, as he interprets it, in man, and that when trover was brought for a slave—

Mr. MASON:—Not as I interpret it, but as interpreted in England.

Mr. CRITTENDEN:—I know that. He says it may be so interpreted; that when trover was brought for a slave in England, the judges decided there was no property in man. Could the same judges, sitting in a court in New Mexico, have given that decision when the law there established such property? In such a case, their decision must be different. They are referring, according to him, to two contradictory rules: one establishing slavery and acknowledging property in the master, and the other the common law denouncing and deciding against the right of property in man. This could not have been their intention, nor can this be the construction. We cannot consider these gentlemen to have changed their opinion from one sentence to another, to have left an incongruity and a contradiction expressed upon the face of the same section.

Nor, sir, do they refer—and that is my answer to my friend from Virginia—to the common law as furnishing the rule of decision at all. The proceedings shall be according to the course of the common law; that is all. If any violation is done to the rights of the master, he may sue; and, for his greater security, he may sue in the Federal courts; and, for greater security still, the law shall be administered according to the course of the common law. The common law is referred to as determining the mode of trial. We say according to the course of the civil law, and we say according to the course of the common law. What do we mean? We mean this marked and characteristic and essential difference: the course of the civil law is for the judge, without the intervention of a jury, to decide facts as well as the law. The common law takes away from the judge the power of deciding the facts, and demands a trial by jury. What this convention mean, therefore, by this provision is, that trial shall be by jury, according to the course of the common law. That is the explanation of the difficulty, and thus all doubt is removed. By these plain provisions—plain in themselves, and made plainer still by being taken with the context—they say you shall have your rule of right, according to the law of the Territory, which is in your favor as to the right to hold persons as property; that law shall be your security; you shall have a remedy for any violation of that right in the Federal courts, and you shall have that remedy, not according to the course of the civil law, in which the judge is to decide, who might be against you, but in which a jury shall be called to decide the fact according to the course of the common law. That is the whole of it.

Mr. MASON:—Mr. President—

Mr. POLK:—If the Senator will allow me, before the Senator from Kentucky sits down, I will ask him if the Mexican law establishes slavery, or if it does any thing more than to protect the right of the master to his slave? If that is the only establishment of it, then it is established by implication merely.

Mr. CRITTENDEN:—I really do not know whether the gentleman would consider it as establishing or merely protecting. I do not know that there is a law in any State of the Union that eo nomine establishes slavery; I do not know.

Mr. POLK:—The object of the inquiry was this: it has been contended heretofore that, by the law of Mexico, there could be no slavery there; and then there is another law of New Mexico professing to protect the right of property. I have never seen that New Mexican law.

Mr. CRITTENDEN:—I believe I have answered the gentleman as far as my information extends. I have examined that law. It is as strong in favor of the master as the laws of Kentucky or Missouri. I believe it is the law of Mississippi transcribed literally, verbatim. That is my understanding. The law is as complete on the subject as the law of any State that I know of.

Mr. MASON:—Mr. President, if the Senator from Kentucky is right, and, in the interpretation of this section, the courts are necessarily to consider the expression, "according to the course of the common law," to which slaveholders are referred for the enforcing of the relation of master and slave, as referring only to common law remedies, then I am at no loss to conceive, after our experience of judicial interpretation against slavery, by what sort of artificial and sophistic reasoning those judges of the Federal courts may feel themselves bound to withhold the remedy. Why, sir, are we to shut our ears and our eyes against experience passing before us every day? What is the present Constitution? The second section of the fourth article is in these words:
