Total for 107,500 miles of canals and canalized rivers—$45,930,-245, 12,500 miles of navigable river, at a cost of (?) for maintenance. This $45,930,245, estimate does not include the cost of main-taining a navigable channel in 12,500 miles of river, including the por- 1/7 tion of the Mississippi between Cairo and the mouth of Red Riverand the Hudson between Troy and New York. In the portion of theMississippi River last mentioned, we find (see pages 269 and 270 ofthis discussion) that the annual cost of maintaining a fourteen-footchannel for 762 miles would be $9,160,, or a capitalized valueof a little over $300,553 per mile; but we do not know what portion. HOUSE BOATS ON THE SHANEEN CANAL, CANTON, CHINA. (From The Reader, January, 1908.)China is one country on earth where navigation of Inland Waterways isnot yet an Anachronism. Even in China, railroads are now rapidly superseding the rivers andcanals. of the whole would require such maintenance expenditures, and must,therefore, leave out of our estimate the annual cost of maintaining anavigable channel in the 12,500 miles of river. The adult male population of the United States is probably about22,000,000. Ignoring the cost of maintaining a navigable stage in the 178 12,500 miles of navigable rivers, and including only the $45,930,245,, estimated first cost of canals and canalized rivers, we hav
