DUST AND ITS DANGERS. 85 



panics see to it that their conveyances are 

 actually frequently cleaned. 



A railway-car which comes in from its hun- 

 dred-mile trip is, when vacated by its occupants, 

 usually an extremely filthy place ; dangerous 

 even, if by chance it has borne an uncleanly 

 passenger afflicted with bacterial disease. And 

 yet, as every observant person who travels 

 much has often seen, these cars may be started 

 out on the return with their full loads of fresh 

 victims, after no other cleaning than a few 

 random broom-sweeps and a few flips of the 

 feather-duster over the window-seats and plush- 

 covered chairs the windows usually tightly 

 closed meanwhile, and the doors, possibly, but 

 by no means always, opened. 



But here again, if the travelling public will 

 not protest against the filthiness of many pub- 

 lic conveyances, and insist upon a more intel- 

 ligent and careful system of cleaning, matters 

 will probably remain as they are. Where com- 

 petition exists between the transporting com- 

 panies, persistent public protest will in the end 

 be heeded. Where competition does not ex- 

 ist, woe to the traveller.
