Of course I wrote to George Orcutt at once of our great discovery, and he came up at once to examine the situation. On the whole, it pleased him. He could not take the site I proposed for the dam, because this very clay there made the channel treacherous, and there was danger that the stream would work out a new career. But lower down we found a stony gorge with which George was satisfied; he traced out a line for a railway by which, of their own weight, the brick-cars could run to the centrings; he showed us where, with some excavations, the fly-wheels could be placed exactly above the great mill- wheels, that no power might be wasted, and explained to us how, when the gigantic structure was finished, the BRICK MOON would gently roll down its ways upon the rapid wheels, to be launched instant into the sky! Shall I ever forget that happy October day of anticipation? We spent many of those October days in tentative surveys. Alice and Bertha were our chain-men, intelligent and obedient. I drove for George his stakes, or I cut away his brush, or I raised and lowered the shield at which he sighted and at noon Polly appeared with her baskets, and we would dine al fresco, on a pretty point which, not many months after, was wholly covered by the eastern end of the dam. When the field- work was finished we retired to the cabin for days, and calculated and drew, and drew and calculated. Estimates for feeding Irishmen, estimates of hay for mules,--George was sure he could work mules better than oxen,--estimates for cement, estimates for the preliminary saw-mills, estimates for rail for the little brick-road, for wheels, for spikes, and for cutting ties; what did we not estimate for--on a basis almost wholly new, you will observe. For here the brick would cost us less than our old conceptions,--our water-power cost us almost nothing,--but our stores and our wages would cost us much more.
