TIMBER REGIONS — SUPPLY AND PRODUCTION.

Upon a third plat cxcoptionally licavily tirahered, 45 trees were counted, of wliicli ."> trees 

 were 25 inches in diameter at breast hiij,li, tlie clear timber averaging 50 feet in lengtli; 12 trees 

 22 inches in diameter at breast higii, length of timber 5i» feet, and 28 trees 1(> to IS inches in 

 diameter, average lengtli of timber estimated at 30 feet. Such a stand would indicate a yield of 

 ineichantable timber of at least 15,000 feet, board measure, to the acre. All over this lower 

 division boggy tracts are frequently met with, in which the sour, black soil is covered with 

 si)li;ignnm, or bog moss; these support only a few scattered jjiiics. On many of the steeper ridges 

 tlie soil is pure sand and the pine growth is small and inferior, being largely replaced by Barren 

 Oak, Sparkleberry, and the evergreen heather like shrub Ceratiola ericoides. 



In this lower division of the maritime pine belt the manufacture of lumber and the produc- 

 tion of naval stores is carried on most actively. These products liud their outlet chiefly ;it Mobile, 

 while more than one-third of the lumber exported from Pensacola (to the amount of at least 100,- 

 000,000 feet annually for the past few years) is also derived from this division. In the upper half 

 of the maritime pine belt, with the appearance of the outcroi)S of limestones and limj- marls of the 

 Lower Tertiary (Eocene) formation, the country becomes more broken, with steeper hills and wider 

 valleys, and a change in the character of the Hora takes place, particularly manifest in the nature 

 and distribution of the tree growth. In the fertile valleys and on the lower flanks of the hills 

 broad-leaved trees, mostly Post Oak, Black Oak, Mockernnt, Bitternut, Pignut, and Magnolia 

 prevail, interspersed with Shortleaf Pine, Loblolly Pine, and Eed Cedar — the Longleaf Pine 

 occupying sporadic patches of drifted sands and pebbles. On tlie steep and frequently wide 

 ridges capped by these deposits, and on the rugged hills of the buhrstone and flinty cherts this 

 tree forms the principal growth, and is in the openings more or less associated with broad-leaved 

 trees. From this commingling of cone-bearing and deciduous trees and the alternations of pine 

 forest and oak woods, this upper division has been designated as the region of mixed growth, 

 which at a i-ough estimate can be said to cover about 5,000 ,s(juare miles. 



In the deep soil of light loam and strong loamy sands the Longleaf Pine attains a splendid 

 growth and the number of large trees on a given area is greater than found in the lower division. 

 The following measurements of 5 trees felled for test logs fairly represent the average dimensions

Many of the trees of larger size were found affected by wind shake in the direction of the 

 rings of growth (ring-shake), in many instances impairing greatly the quality of the timber. The 

 forests on these hills are open, with a comparatively small number of young trees. Upon 1 acre 

 selected at random 46 trees were counted; of this number were found 4 trees of a diameter of 25 

 indies breast high, and the length of timber about 40 feet; 10 trees of a diameter of 22 inches 

 breast high, and the length of timber about 3(> feet; 26 trees of a diameter of IS inches breast 

 high, and the length of timber about 30 feet; 6 trees of a diameter of 15 inches breast high, and 

 the length of timber about 25 feet. 



On the average each one of these trees would yield about 400 to 450 feet, board measure. On 

 another acre 44 trees were found (littering in their average dimension but slightly from the above, 

 and indicating a yield between 18,000 and 19,000 feet of lumber to the acre. In this upper part of 

 the coast pine belt lumbering and turpentine orcharding have not developed to any great extent, 

 owing to its inaccessibility, llowever, where railroads traverse the section, the manufacture of
