The pocjrer grades of tupelo gum fur- nish material for boxes and egg crates, and timbers and planks are used ex- tensively as flooring for depots and \\'arehouses. where there is heavy wear on the floors. Though the wood is not durable in the soil, it has proved satisfactory, when treated against de- cay, for such uses as cross-arms of telephone poles, cross-ties in mines, and wood paving blocks. In the bottomland Cypress for- ests of southern Illinois, the Tupelo Gum constitutes between 1!) and "in per cent of the stand. Among 22 species of trees, it stands second only to Cypress, with an average of IG trees to the acre. Its potential yield, however, is in excess of all species, amounting to 15,0(10 board feet per Fig. 106. Distribution of the Tupelo 1 â 1 ^ ⢠ij Gum. acre, or nearly twice the Cypress yield. In 1910, about 9 board feet of tupelo gum was produced in the southern counties of Illinois; but in 1925, the amount had fallen to 10L^OOO board feet. This may be taken to indicate that the Tupelo Gum, like the other trees of the Cypress swamps, are fast disappearing.
