T PI E MAPS 



Following the charts will be found eleven maps, ten of which show, by gradation 

 of color or varying intensity of tint, approximately, the prevalence of certain diseases 

 throughout that part of the United States wherein the draft was enforced. The charts 

 of Class III cover the same territorial area subdivided into States only, while the maps 

 show each congressional or enrollment district. 



The maps are designated as " Plate I," " Plate II," and so forth, and each has its 

 particular color-scale, whereby the approximate ratio of exemption may readily be 

 determined ; but, without the use of the scale, the prevalence of a disease in one district 

 or section, relatively to any other, is seen at a glance. 



Plate I, (devoted entirely to the deiinition of the enrollment-districts as they 

 existed in 1863-'64,) in which each district bears its designating number, has an im- 

 portant connection, not only with the other plates, but with some of the tables of Vol. 

 II as well, especially Tables 21, 22, and 23. . It will also aid the reader materially 

 in understanding much of that portion of the work devoted to the final reports of the 

 surgeons of the boards of enrollment. 



It was, of course, found impracticable to show upon so small a scale the bound- 

 aries of such districts as lie wholly within the hmits of cities ; but a remedy for this 

 defect will be found in the complete definition, of such districts, printed upon the map. 

 The subject of the relations existing between disease, or certain diseases, and what 

 may be comprehensively termed locality, has already been treated of in the comments 

 and remarks upon the charts of Class III, and need not be reverted to ; and, upon the 

 indications of these tinted maps, very little can be said to make them more hitelligible 

 to the reader. It may, however, be remarked that in their preparation one object was 

 kept steadily in view, namely, that of presenting an illustration which, as nearly as 

 possible, should be complete in itself, and not wholly unintelligible, except in con- 

 nection with the letter-press of the work — hence the various explanatory notes and the 

 concise statement contained in the title : Congressional Districts. Drafted Men. 



For a statement of the exact ratios, (the plan of the maps admitting of approxima- 

 tions only,) the reader is referred to Table 22, (Vol. II.) The number of examinations 

 is the same in each case, namely, 501,002. ^^^
