In a rough way I estimated that each ingot weighed at least five pounds, and as each of the little boxes contained ten of them the value of every single box stored there was not less than fifteen thousand dollars. As well as I could make out, the boxes were in rows of ten and there were ten rows of them--which gave over a million and a half of dollars for the top tier alone; and as there certainly was an under-tier the value of my treasure at the least was three millions. But actually, as I found by digging down through the ingots until I came to the solid flooring, there were in all five tiers of boxes; and what made the whole of them worth close upon eight millions of our American money, or well on toward two millions of English pounds. My brain reeled as I thought about it. The treasure that I had possession of was a fortune fit for a king! I had swung myself up from the little chamber and was standing in the cabin while I made these calculations, and when at last I got to my sum total I felt so light-headed that it seemed as though I were walking on air. Indeed, I fairly was stunned by my tremendous good fortune and could not think clearly: and it was because my mind thus was turned all topsy-turvy, I suppose, that the odd thought popped into it that in the matter of weight my gold ingots were pretty much the same as the tins of beans to get which I was about to return to the barque--a foolish notion which so tickled my fancy that I burst out into a loud laugh. The jarring sound of my laughter, which rang out with a ghastly impropriety in that deathly place, brought me to my senses a little and made me calmer. But my mind ran on for a moment or so upon the odd notion that had provoked it, and in that time certain other thoughts flashed into my head which had only to get there to spill out of me every bit of my crazy joy. For first I realized that since I could carry only the same weight of gold that I could carry of food my actual wealth was but a single back-load, which brought my millions down to a few beggarly thousands; and on top of that I realized--and this came like a douse of ice-water--that for every ingot that I carried away with me I must leave a like weight of food behind: which meant neither more nor less than that my great treasure, for all the good that ever it would be to me--so little could I venture to take of it on these terms--might as well be already at the bottom of the sea.
