Dr.Gorgas had already performed an inestimable service by caring for the sanitary conditions so thoroughly as to make the Isthmus as safe as a health resort.

Colonel Goethals proved to be the man of all others to do the job.

It would be impossible to overstate what he has done.

It is the greatest task of any kind that any man in the world has accomplished during the years that Colonel Goethals has been at work.

It is the greatest task of its own kind that has ever been performed in the world at all.
