They had but a limited supply of hard corn, from which they selected the best ears for the next year's planting. These they braided together by the husks, and hung up in yellow festoons from the rafters of the hut, which they continued to use as a storehouse. Much of what remained of their small crop would be needed by the fowls in the winter, and up to this time they had made no use of it for their own food. Meal was out of the question, and to break the flinty kernels between stones was a tedious process to which they had not yet been forced to resort. The presence of the lye, however, suggested to Bromley the hulled corn of his New England grandmother, which he had seen her prepare by soaking and boiling the kernels in a thin solution of lye. By this means the hulls or skins were removed, and after cleansing from potash, and boiling all day, the unbroken kernels became as white and tender as rice. This satisfied the three soldiers for a time, and made an agreeable addition to their diet of bear steak and potatoes. In the mountains of Tennessee Lieutenant Coleman had once seen a rude hydraulic contrivance called a Slow-John, which was a sort of lazy man's mill. To construct this affair it was necessary to have a bucket, which Bromley set about making by the slow process of burning out a section of chestnut log with the red-hot ramrod of a carbine. At a short distance above the house, the branch which flowed from the spring, after making its refreshing way between grassy banks, tumbled over a succession of ledges which ended in a small cascade, and twelve feet below this waterfall there was a broad, flat rock which laved its mossy sides in the branch, and showed a clean, flat surface above the level of the water. Below this rock they built a dam of stones, by means of which they could flood its surface. Four feet up-stream from the rock a log was fixed from bank to bank for a fulcrum, and upon this rested a movable lever, the short arm of which terminated above the submerged rock, while the long arm just touched the water of the cascade. A wooden pin set in the under log passed through a slot in the lever, so as to hold it in position and at the same time give it free play. Another flat stone of about thirty pounds' weight, which was the pestle of the mortar, was lashed with grape-vine thongs to the short arm of the lever directly over the submerged stone. To the long arm was attached Bromley's bucket, bailed with a strong wire, and so hung as to catch the water of the cascade. As the bucket filled and sank, its weight raised the flat stone higher and higher above the submerged rock until the bucket met a bar fixed to tilt its contents into the stream, when the upper millstone came down upon its fellow with a fine splash and thud. After a wall of clay had been built about the surface where the two stones met, to keep the corn in place, the Slow-John was ready for work.
