New tanks of wood are generally shipped unlined, as,if the weather is cold, the asphaltum will be cracked inhandling the tank, and if the weather be hot the liningis likely to be found evenly spread over the bottom ofthe tank to the depth of six inches or more, while thereis nothing on the sides.

To find the capacityof any tank, multiply the length, breadth and thicknessin inches and divide by 231, as 231 cubic inches makeone gallon.
