 however, the figures for imports and exports are sufficient. They 

 give a good idea of the economic condition of the country and that 

 is what we want.

Figure 6. Health and Business in Germany 



Figure 6 shows the German variations of health, imports and 

 exports so far as the data are available. The curves for imports 

 and exports have been shoved to the left two years, since this 

 appears to be the amount of delay between conditions of health 

 and those of commerce. Notice* in the first place that the German 

 curve for deaths does not move up and down anything like so 

 violently as that of the United States. This is partly because it 

 is based on the entire country instead of on only about a seventh 

 of the total population, as in the United States. It is also because 

 the variations from year to year are actually less than in this 

 country. They are less because the Germans are undeniably 

 ahead of us in the public care of health. They are also less 

 because the climate of Germany is less strenuous than that of the 

 United States. Examining the curves in detail it appears that 

 in Germany both imports and exports vary in fairly close har- 

 mony with health. The health maximum of 1881 was followed 

 in two years by a maximum of both imports and exports. In the 

 case of the succeeding minimum, however, there was no delay in 

 the case of imports, while the minimum of exports actually
