In 1904 and 1905 there were 35 deathsof employees from yellow fever on the Isthmus, but by the end ofthe latter year the situation was under control. In May, 1906, therewas one case at Colon and there has not been a single case on theIsthmus since that date. The deaths from malaria have been reduced from 233 in 1906 to3 in 1916 with a larger working force, and the table of case ratesbelow quoted from Hoffmans monograph is eloquent of the resultsachieved.
