with an endless belt provided with buckets, like a grain elevator. These dip into a box of dry sand and discharge it upon a large wheel like an overshot water-wheel, which it turns as water would. The sand is discharged again into the box and thus is used over again endlessly. We think the man has not patented his invention; he has missed a fortune which somebody else will pick up.
