Prominent officers of the Engineer Corps have recently even gone so far as to assert in print that waterways are not dependent upon the conservation of the forests about their headwaters. This position is opposed to all the recent work of the scientific bureaus of the Government and to the general experience of mankind. A physician who disbelieved in vaccination would not be the right man to handle an epidemic of smallpox, nor should we leave a doctor skeptical about the transmission of yellow fever by the Stegomyia mosquito in charge of sanitation at Havana or Panama. So with the improvement of our rivers; it is no longer wise or safe to leave this great work in the hands of men who fail to grasp the essential relations between navigation and general development and to assimilate and use the central facts about our streams. Until the work of river improvement is undertaken in a modern way it can not have results that will meet the needs of this modern nation. These needs should be met without further dilly-dallying or delay.
