The hydro-electric resources of the super-power territory that have not been developed to their full capacity, if at all, comprise power-sites in the Adirondacks; along the Hudson, the Raquette, and the Black rivers; along the upper reaches of the Delaware and the lower ones of the Susquehanna and last--and greatest--that of the St. Lawrence River itself, taken just below Ogdensburg, New York. This last part of the project ties up very closely with the St. Lawrence Ship Canal project, an international scheme in which the United States and Canada shall share the cost and the benefits, both in power and in enlarged water traffic possibilities. It is estimated that more than 1,400,000 horse-power can be generated in this plan, of which one-half would be available for the use of this country. At present the whole St. Lawrence River canal scheme is under bitter political attack, which renders it unlikely that it will come quickly into effect. That it will not come eventually is hard to believe. When all is said and done, however, this super-power plan, so sweeping as to be all but staggering to the imagination, and yet sponsored by the shrewdest and most far-seeing of American engineers, is based primarily upon the consumption of coal at the mines rather than in distant factory engine-rooms, central power-stations, or locomotive boilers. It is estimated that it can be operated at a saving of at least 30,000,000 tons of coal each year to the industries and railroads of the district which it embraces, or, at a modest average of eight dollars a ton of coal, $240,000,000 a year to commercial America. Shimmery copper wires will carry silently and continuously what will amount to at least one half of the coal tonnage not carried by the railroads for power and lighting purposes. A copper wire knows neither snow, blockade, nor traffic congestion. And railroad experts estimate the super-power plan as a saving of another $150,000,000 annually in coal freights. A total of more than a million dollars a day saved in just one corner of American industry is not to be sneezed at, even in these days when we talk so easily and carelessly in billions.
