Inasmuch as no quarantine measures of our seaports can be effective against the importation of diseases without uniformity in time and method. that Congress bo memorialied to establish a uniform system of quarantine under national supervision. Indeed. all the southern cities express a desire for more effective quarantile laws and regulations and will cordially cooperate with the governmental authorities in devising and perfecting some system that will shield our exposed coast cities and inland towns "from the pestilence that walketh in darkness and the destruction that wasteth at noonday." There gre two diseases against which the provisions of this bill are designed particularly to guard our people. and the ravages of which two diseases in the United States have been appalling. These diseases are Asiatic or Indian cholera and yellow fever. Cholera is caused by the access of a specific organic poison to the alimentary canal. which poison is developed spontaneously only in certain parts of India. Science has located the very birthplace of this disease. and has demonstrated that it never appears spontaneously outside of these welldefied boundaries.
