Here is a little information which will help you solve the vexing problem that is apt to be a hardy annual, that is, how much coal to order in order to fill the bunkers, but without have to put some in an old barrel in the outhouse. A ton of egg coal contains from thirty-two to thirty-eight cubic feet, averaging about thirty-five. By measuring the cubical contents of your bin you will be able to estimate how much to order to fill them. This may be done by multiplying together the length, breadth and depth of your bin.
