The Alcohol Problem in the Light of Coniosis. 



Robert Hessler. 



The alcohol problem is a very important one. so important that it has 

 entered politics. Men vote wet or dry. and women are seeking suffrage. 

 It* women vote and vote "dry'*, will we have prohibition V Will the pass- 

 ing of a prohibition law tree the State from the alcohol problem".' 



There are all sorts of factors that enter into the question, and there 

 are all sorts of problems connected with the alcohol problem. Here I de- 

 sire to call attention to one that is usually neglected, the dnst problem 

 or the bad air factor. (How to develop the subject in a 20-mmute paper 

 is in itself a problem. Technical details must be omitted. ) 



The study at first was one of individuals and then one of the family. 

 and finally of the entire relationship. I shall show a number of charts. 

 Some represent several hundred individuals and are so full of details 

 that it would require considerable time to go over them. Most of these 

 (harts will be referred to very briefly in order to give as much time as 

 possible to the deductions or conclusions. 



A word regarding the charts that were shown: On account of ill > 

 difficulty of reproducing them properly in colors they are omitted here; 

 only one is given to illustrate the general idea, how the data were dia- 

 gramed. Perhaps the few references to charts will be understood in ths 

 light of the diagrams. In the original charts, or genealogies, males were 

 indicated by blue lines; females by red lines. Black lines represented mem- 

 bers whose sex was unknown. Short lines indicated individuals who diel 

 young. The children, silis. are given in the order of age. beginning at the 

 left. 



Intermarriages are shown by short lines, drawn upwards. 



No offspring (that is. race suicide. I is indicated by a circle. 



The accompanying diagram represents three generations. - 



'Coniosis. For ;in explanation of the term and of the theory of Coniosis see Proc. Ind. Ac-ad.

•The original blue lines males) are here re resented by Light lines, and the rod (females bj 

 heavy black lines.
