from uncommon; and the latest sanitary rules emphasize the importance of systematically catching them.  Medical experience has shown that if houses are kept clear of mosquitos, there is very little fever, even in places where the water pools and channels are left unsterilized.  Wire screening, supplemented by a butterfly net, is the great preventive.  But we can not attain the good without an admixture of evil:  behind the wire screening the indoor atmosphere becomes very oppressive.  Yellow fever, the scourge of the isthmus in former days, has been completely eradicated.  Admissions to hospital for malarial fever amount, it must be confessed, to several thousands a year.  But, judging from the terrible experiences of the French Company, were it not for these precautions fever would incapacitate for long periods the whole of the staff.

The hospital, a heritage from the French, is a village of wooden buildings set upon a hill overlooking the Gulf of Panama, in the midst of a charming study in tropical gardening.  It is managed with an energy which explores to the uttermost the medical experiences of other tropical countries, and is not afraid of improving upon time-honored methods.  The daily dose of quinine is seldom less than forty-five grains, and patients are not allowed to leave their beds until their temperature has remained normal for five days at least.  Complaints of deafness are disregarded; if the patient turns of a blue color he may be consoled by a dose of Epsom salts.  It is claimed that by this drastic treatment the relapses are prevented which, in India and elsewhere, probably account for at least nine attacks out of ten.

Democracies are not always fortunate in the selection of their executives.  But Mr. Roosevelt’s Government was gifted with the wit to find, in the United States Army, men who could carry out this big work, and with the good sense to employ them.  So much is told of the commanding influence of Colonel Goethals, the chief in command; of the administrative talents of Colonel Gorgas, the head of the sanitary department; of the engineering skill of Colonel Sibert, the protagonist of the Gatun dam, that an Englishman must wish to claim kinship with these American officers who are making so large a mark upon the surface of the earth.  Devotion to the great work in hand has exorcised meaner feelings, and you will hear little of the “boost” which we are tempted to associate with the other side of the Atlantic.  I asked Colonel Sibert whether his initial calculations had needed much correction as the operation developed.  “Our guesses” he replied, “have been remarkably fortunate.”  The medical staff relate with delight how a British doctor, sent by the Indian Government to study their methods, being left to himself for half an hour, succeeded in catching quite a number of mosquitoes of a very noxious kind within the mosquito-proof precincts of a hospital ward.
