While it mav l:>e onlv se\en inches high at seven years of age, its tap root may all of se\en feet long, and when the tree is full grown this tap root is often feet long. After reaching seven years of age, the tree grows rapidly until it is sixty or seventy years old, when the growth becomes slow again. The bark of the tree is thin and orange brown, sepa- rating on the surface into large, papery scales which lie flat against the trunk. The wooil is heaxv. exceedingly hard and strong. It is usualh' tine-grained and duralde. orange color, some- times of a \ery deep shade. It is largely used for build- ing, both framing, and interirir tini'-hing: als(j bridging, rail- w ay ties, fencing; and for masts and sp a r s. A 1- t h o u g h it makes a hot fire, it Ijurns slowly and warehouses and storage houses built of it are said to be of slow burning construction. It is rich in resinous materials and thousands of acres uf trees are tapi)ed annually for the "gum" ( oleo-resin I from which resin and turpentine are derived. 'I'he older methiuls of obtaining the "gum" resulted in killing a great many of the trees in a \'erv few vears; recent improved modern methods are nut so harmful. The wiiod, hiiwever, is not injured by this tapping. Unless protection tire and means of rei)roduc- tion are looked to, it is expected that there will be ])rac- ticallv no longleaf pine trees left in a few years. They are being cut for lumber in large quantities every year, and wilhiiut protection they are likely gradually to be- come extinct.
