After this, to keep our minds from wandering toward the green chest, we started the manufacture of gunpowder on a large scale. The raw material, rotting stone, could be procured from the sand heap and dump, which at that date (before the rise of city improvement associations) adorned the banking at the end of the frog pond. This dump had many attractions, not the least of which were the squash vines which trailed over it. They never got beyond the blossoming stage, but that did not trouble us. The possession of raw squashes would have availed us little. The flowers were interesting, and I scarcely need to point out the value of the stems. We cut a slit near one end, and they became in our hands trumpets with which to blow soul-animating strains. It is, of course, necessary to scrape off the prickles with a jack-knife, or the lips of the performer are apt to suffer. But these were by the way. The rotting stone, red, gray, brown, and black, was the most valuable product of the dump. We carried it to a broad, flat piece of slate which covered a cistern just outside the basement windows. Here, with hard rocks, we ground it fine. It then became, by the chemistry which worked so quickly in those days, gunpowder. The black dust was the ordinary article. Mixed with red or other colors, it was transformed into various high explosives. Then we stored it in packets in the basement, where it might be drawn upon in case of need--any sudden attacks by Indians or pirates, for instance. The day on which we stored the powder was not long after the Fourth of July. Our operations in the basement had to come to an end on that day, for Grandmother Bradley and Aunt Josephine were going away for a week. The house was to be closed, and Jimmy would stay with his Grandmother Toppan in the country. The last time we entered the basement our eyes wandered toward the green chest. But neither of us spoke about it. I wondered if the chest would be stolen, or be burned up, or should I die and never look inside it? Already the little glass ships and fishes had become less real, though more beautiful, than the folks of elf-land. What small hope I had ever entertained of seeing them was dwindling to a pin-point. I was never troubled by any suspicion that the tank, the ocean, and the glass creatures existed only in Jimmy's imagination. Such doubts did not fret me then, nor afterwards. The green chest remained one of the mysteries of the believing years. CHAPTER IX WHITE PEACOCKS During the time that Jimmy stayed at his grandmother's farm--a period that was lengthened to more than two weeks--we were all agitated by the approach of a circus. Excitement had reached such a pitch that when, three days before circus-day, Jimmy invited me to make him a visit, I was in some doubt whether I ought to venture so far afield.
