For ballast, of course we should have nothing but platinum, unless the owner grudged the expense, when we might put the top tier of gold.
"But by that date I hope we won't care for sailing in such a sluggish element as the water. I firmly believe that some day the air will become as easily traversed as the earth or ocean."
