Here is another diagram for you, Jonathan, showing the comparative mortality from Consumption among the workers engaged in six different industrial occupations and the members of six groups of professional workers. [Illustration: DIAGRAM Showing Relative Mortality From Tuberculosis. Deaths per 100,000 living in the same occupation Marble and stone cutters. 540 Cigar makers and tobacco workers. 476 Compositors, printers, pressmen. 435 Barbers and hairdressers. 334 Masons (brick and stone). 294 Iron and steel workers. 236 Physicians and Surgeons. 168 Engineers and Surveyors. 145 School teachers. 144 Lawyers. 140 Clergymen. 123 Bankers, brokers, officials of companies, etc. 92] I want you to study this diagram and the figures by which it is accompanied, Jonathan. You will observe that the death rate from Consumption among marble and stone cutters is six times greater than among bankers and brokers and directors of companies. Among cigar makers and tobacco workers it is more than five times as great. Iron and steel workers do not suffer so much from the plague as some other workers, according to the death-rates. One reason is that only fairly robust men enter the trade to begin with. Another reason is that a great many, finding they cannot stand the strain, after they have become infected, leave the trade for lighter occupations. I think there can be no doubt that the _true_ mortality from Consumption among iron and steel workers is much higher than the figures show. But, taking the figures as they are, confident that they understate the extent of the ravages of the disease in these occupations, we find that the mortality is more than two and a half times greater than among capitalists. Now, these are very serious figures, Jonathan. Why is the mortality so much less among the capitalists? It is because they have better homes, are not so overworked to physical exhaustion, are better fed and clothed, and can have better care and attention, far better chances of being cured, if they are attacked. They can get these things only from the labor of the workers, Jonathan. _In other words, they buy their lives with ours. Workers are killed to keep capitalists alive._
