These chambers usually meet twice each month and they keep in close touch with each other, working out plans that will be for the good of the whole country as well as for their special localities. Many of the largest undertakings in France have been begun and carried out largely by chambers of commerce. The new port at Marseilles, which will cost about two hundred million francs, is an example. For this work the chamber of commerce raised six million francs, the government provided a like amount, and with this the chamber was able to finance the improvement, depending on tolls and other revenues to pay the balance in due time. The feature which appealed most strongly to me in these chambers of commerce was the manner in which they are dovetailed with the government in the performance of duties of a nature such as, in spite of their tremendous importance, we Americans generally regard as nobody's business in particular, and which are therefore usually left undone. A national organization of chambers of commerce is maintained in Paris. Part of the expense of each chamber, as well as of this body, is paid by the government. The secretaries of the local chambers have also an organization, and all these seem to work in perfect harmony for the general good. The secretaries are usually professionals, and special courses of training may be had in France for this work. We found that nearly every chamber had its own building and that all were handsomely housed, well financed and extremely effective. They have become a most important part of the government, handling with success many problems that are difficult for a government and which, at the same time, require a certain amount of governmental authority if they are to be disposed of in an efficient manner. In my opinion this country could copy the French system of chambers of commerce with much profit. We are in advance of them in many things, especially in the matter of industrial operations, but they are a century in advance of us in the co-operation needed between the citizens and the government for the highest development of community life and progress. XXIV. THE CARREL METHOD OF TREATING WOUNDS So much interest has been expressed in the new method of treating wounds discovered by Dr. Carrel and bearing his name, and the subject being of such great importance to the cause of humanity and the preservation of human life, I have thought it worth while to give here the following authoritative descriptions of this new and epochal discovery in the science of medicine. It is now generally known as the Carrel-Dakin treatment.
