The next day ushered in a crisis in the affairs of the would-be stationers--the house-raising began. All the men of the settlement gathered to the fore, and the cabins--a substantial double-cabin the larger was, and the other, one room and a loft--went up as if by magic. The stockade, boles of stout young trees sawed off in lengths of twenty feet and sharply pointed at the upper end, the other end deeply sunken into the ground, began to grow apace. The spring was within the enclosure--a point of vast importance in that day, since in times of danger from the Indians it was not necessary to sally forth from the protection of the stockade for the indispensable water-supply for household and cattle. The prospects of many an early station were blighted by overlooking in a period of comparative peace and comfort this urgent advantage, and many a life was taken during some desperate sortie with piggins and pails by the defenders of the stockade, who could have held out valiantly against the savage except for the menace of death by thirst. The officers had urged this point upon the pioneers. "Of course in any emergency," Demeré argued, "the forces at the fort would relieve you at once. But the true military principle ought to govern even in such a minor stronghold. An unfailing water-supply ought to be a definitely recognized necessity in every military post subject to beleaguerment. Otherwise the station can be held only very temporarily; one can lay in provisions and stand a siege, but drouth means death, for surrender is massacre." Nevertheless, eastward at the time, and later in westward settlements, this obvious precaution was often neglected and the obvious disaster as often ensued. The woodland spring within the stockade was a charming and rocky spot with no suggestion of flowing water till one might notice that the moss and mint beneath a gigantic tree were moist; then looking under a broad, flat, slab-like ledge might be descried a deep basin four feet in diameter filled with water, crystal, clear, and brown in the deep shadow--brown and liquid as the eyes of some water-nymph hidden among the rocks and the evergreen laurel.
