"Yorkshire towns have had such a visitation of smallpox, that we read with interest the part played by the tramp genus in spreading it. Last year there were 144 cases of the disease in the West Riding. In nearly every centre affected, the tramp was responsible for its introduction. Thus we find at Keighley, where the greatest number of cases occurred, the infection was brought by a man who had been 'on tramp' seeking employment. The 15 cases at Barnsley were attributed to tramps of the lodging-house class. A recent investigation has shown that out of 138 towns having cases of small-pox, in no less than 100 its introduction was attributed to persons of the same class. At Sheffield, out of 28 importations, 21 were brought about by tramps, and at Huddersfield, 8 out of 13 invasions were traced to similar channels. It is significant, that in districts away from the main roads trodden by these nomads, small-pox was unknown. Clearly something will have to be done with this highly objectionable person if we are not to have small-pox always with us." In a paper on "Tramps and the Part they Play in the Dissemination of Smallpox," read in July of the same year at the Sanitary Institute's meeting, Dr. Kaye said:-- "In the recent prevalence of small-pox, some 12,000 cases have occurred in the provinces (since January, 1902), and experience all over the country shows that the most subtle agency of distribution is not to be found in the close commercial intercourse of our communities, but in the wanderings of the relatively insignificant number of people whom we designate tramps." As a result of the discussion which followed, it was resolved to request the Government to "take into consideration the necessity for legislation to deal more effectually with those resorting to common lodging-houses and workhouse tramp-wards, as a constant and dangerous element in the propagation and dissemination of smallpox." The following year Dr. H. E. Armstrong, Medical Officer of Health for Newcastle-upon-Tyne, published an elaborate report on the same epidemic, based upon inquiries addressed to the Medical Officers of Health throughout the country. As a result of the epidemic, which began in the latter part of 1901, and lasted the two following years, 25,341 cases occurred. As to their origin, Dr. Armstrong came to the following conclusions:-- (1) Of the 126 districts from which returns were received, 111 had been invaded by small-pox in the epidemic, and in 57 or 51 per cent. of these, the disease was first introduced by vagrants. In 25 of these latter districts spread of infection from vagrants occurred. (2) Small-pox was introduced secondarily by vagrants into 58 districts, and, perhaps, into two other, at least 305 times. Such secondary introductions of infection took place with the following frequency:-- Number of Times Number Infection was of Introduced. Districts.
