taneously, and their privacy considered even when under strict 

 supervision. The officers in charge can direct and control all 

 operations from the central part of the vessel, and, being provided 



with separate toilet and 

 disinfecting facilities, 

 can return to their 

 quarters or gain access 

 to any part of the ves- 

 sel without danger of 

 conveying infection 

 and without delay. 

 Fitted with the com- 

 bined apparatus, a boat 

 containing the plant 

 can be run alongside 

 the suspected vessel, 

 which can then be thor- 

 oughly cleansed, disin- 

 fected, and fumigated, 

 the passengers and crew 

 bathed, their clothing 

 subjected to steam ster- 

 ilization, and returned 

 to them uninjured, and 

 all baggage and bed- 

 ding treated to a com- 

 plete disinfection. The crew and attendants have their comfort 

 and health cared for separately. 



Under the direction of A. H. Doty, M. D., health officer of the 

 port of New York, the old side-wheeler Ripple has been re- 

 modeled. She looks new from end to end, and under the name 

 of James W. Wadsworth presents a very trim, businesslike ap- 

 pearance. Inside she is arranged to economize every available 

 inch of space, and is finished in such a manner that no germs of 

 disease can be left to lurk undestroyed. 



The Wadsworth has a twofold duty to perform: the bath- 

 ing and disinfection of passengers, crew, and baggage; and the 

 cleansing, disinfection, and fumigation of their vessel. 



The passengers and crew and their effects are transferred to 

 the disinfecting boat for treatment, and their vessel is thoroughly 

 disinfected before they are permitted to return to it. 



To effect this work with rapidity, there are several separate 

 processes, each with its own set of apparatus, conveniently lo- 

 cated. Each or all can be operated from the central part of the 

 vessel, where the officer in charge of the disinfecting processes is 

 stationed.
