The market for wooden tanks is broadening in spite of the fact that metal tanks are used to a considerable extent. In no other line is there a greater increase in demand for this commodity than by factories where tanks are needed to furnish water for manufacturing and engineering purposes. They are usually elevated to the top of the factory buildings, but most frequently on towers varying in height according to the pressure desired. Water tanks along railroads are in this class and southern white cedar, cypress, white pine, and longleaf pine, in the order of quantity, are the woods used for the staves. Shortleaf pine and hemlock went for tank covers. Tank staves are made of heavy material, the thickness varying according to the size and use of the tanks. Often the staves are as much as three inches thick and they must of necessity be made of the best grade of lumber since tanks are subject to strong pressure besides continued atmospheric changes, and the influence of water and other liquids
