322 THE INVISIBLE WOELD 



You, physician, for you to say whether you will 

 carry the invisible foe from house to house. 



You, surgeon, for you to say whether an infected 

 knife shall complicate the disease with another dis- 

 ease. 



You, health officer, for you to say whether you 

 will prevent nuisances and draw taut the quaran- 

 tine. 



For each and all to say whether epidemics shall 

 sweep away thousands, or whether epidemics them- 

 selves shall be swept away. 



If each grain of sand acts well its part, the sea- 

 shore is well. 



If each drop acts well its part, the ocean is well. 



If each atom acts well its part, the world is well. 



If each individual acts well his part, disease is 

 swept from the earth, and the world of humanity 

 is well.
