During 1912 THE SCHOOL JOURNAL will publish several photographs similar to this picture of a cotton field, showing important phases of industry.

The Pine Tree. I

By FRANK OWEN PAYNE

Useful Trees

The pine tree has been chosen on account of its great value, its wide distribution, and because it is probably the very best type of a tree. Certainly no other tree of the north temperate zone can compare with the pine in its commercial value for general uses. The wasteful way in which the white pine has been cut has rendered it well-nigh extinct, so that its market value is almost as great as that of mahogany. The Government has at last tardily stepped in and efforts to protect existing forests and to reforest the regions where it once grew have been made. It will require many years before the white pine will again become cheap and abundant.

2. Yellow pine is not so easy to work with tools, but its varied and useful products make it a tree of first-class importance. A few of these products need special mention.

(a) Lumber: On account of its great strength it is used extensively for framing and constructive purposes. Its hardness makes it a superior flooring material, especially when selected as "comb-grained" lumber, which presents the edges of the annual rings to the surface.

"Excelsior" is finely shaven material used as packing for furniture, glassware, etc. Cheap mattresses also are made of it.

(c) Distillation products of pitch pine are a leading industry of the Southern States.

Lampblack resembles the soot which collects in stove pipes. It is obtained by imperfect combustion of rosin or tallow. Rosin is burned in cast-iron pots. The dense smoke is conducted into a chamber, the walls of which are hung with canvas. On these canvas walls, the lampblack gathers. It is used chiefly in the manufacture of printer's ink.

Turpentine enters into the mixing of paints. It is also used in medicine, especially in the making of liniments.

Pitch is used to render cordage waterproof and prevent wear and decay.

(d) Pine needles from the long-leaf pine yield a fiber which is used for stuffing pillows, mattresses, and in the manufacture of mats and rugs. An oil known as pine-needle oil is extracted from pine leaves. It is used as a solvent and it is said to have value as a medicine. The leaves, themselves, are often stuffed into pillows and cushions because of their resinous odor, which reminds one of the pine woods. (e) Rosin is of great commercial value. A partial list of its uses are as follows:-It is used in the manufacture of cheap yellow laundry soaps, candles, varnishes, paper sizing and waterproof building papers. It is employed in calking ship bottoms. With tallow and beeswax, rosin forms grafting wax. Tinners use it as a flux in soldering. Medicinal plasters and "Sticky flypaper" also contain it. A rectified rosin is used by violinists for "rosining their bows." The bow is made more resistent in its passage over the violin strings, thus increasing the friction and making better vibration.

Note. For manner of gathering and preparing turpentine and rosin see SCHOOL JOURNAL articles on stems and stem products.
