I find that the law. the only statute in regard thereto. conies to us fron 1799. and that is my recollection. Sir. I do not desire to make the stastement positively. because I have had no time to verify my recollectin . but it is my recollection that that statuto was enacted when the pestilence was sweeping over the land. when the great cities of the country were exposed to the ravages of Asiatic cholera. anl it is my recollection that there was then an attempt made to see whether the General Government could not do something to protect these cities against pestilence. and the fathers of the Constitntion in that early Congress assembled decided that all that the General Government could do was to provide that the officers of the General Government should confer with the officers of the State governments in making effectual the provisions and regulations which the States had established in regard to quarantine. Up to this date the General Government has never yet. goe further than to say to its revenue officers and its other officers. Obey the laws which the States have made. aid the State officers to carry ont the State laws.
