744 THE PRESENT ASPECTS OF THE PANAMA CANAL. 



great hospital on the slope of Ancon Hill, with its 700 beds, has been 

 put in excellent working condition, while the sanitary forces of the 

 Commission have already rendered highly efl'ective services toward 

 bringing the entire Zone into sanitary condition, especially in the 

 extermination of mosquitoes. Boards of health of high character 

 and excellent quarantine organizations have been established both at 

 Panama and Colon. Although four sporadic cases of yellow fever 

 have occurred in Panama within the last six months, the infection 

 has not spread from any case, in consequence of the vigilan-ce of the 

 medical and sanitary forces. The general health of the Isthmus has 

 been good and there seems to be a certain promise of excellent sani- 

 tary conditions hereafter, such as to enable the forces of the Commis- 

 sion to perform their work in safety from epidemics and with the 

 highest degree of efficiency obtainable in the Tropics.
