BY RoBERT B. MILLER, Forester, .Natural History Survey. INTRODUCTION The forest area in Illinois to which this report applies is bounded by the Mississippi River on the west and the third principal meridian on the east, and extends in a north and south direction from Thebes, in Alex­ ander county, to Oiester, in Randolph county. It comprises all of Jack­ son county and portions of Union, Alexander, Pulaski, and Randolph countie , a total of 697,286 acres. It forms the western part of the Ozark highlands of southern lllinois ( Colyer, '22), a region which extends across the state for 75 miles, with an average width of about 25 miles, from the mouth of the Big Muddy on the Mississippi to Shawneetown on the Ohio. The highest elevation of this highland belt is "Williams Mountain" (1,065 feet), in the northeastern part of Pope county, Bald Knob, in Union county, coming next, with an elevation of 1,025 feet. The difference of elevation between the crest and the base of the Ozarks is often 500 to 600 feet. A relief map of the state hows that this entire highland region includes the '-Outhem parts of Jackson, Williamson, Saline, and Gallatin counties, almost the whole of Union, Johnson, Pope, Hardin, and Alexander counties, and a part of Massac county.

Species of minor importance are ash, elm, and red gum, with a few others such as walnut, mulberry, sassafras, butternut, and hackberry occurring only occasionally. Combining the results obtained on the 182.32 acres at Alto Pass and Jonesboro, we get the following table of yield by species in board feet, with the per cent of the entire amount that each forms.

With this number as a basis for estimate'" it was assumed that southern Illinois in normal times produced 500,000 and that 300,000 of these at least would come from this region; the amount of sawed lumber was obtained by adding to the actual output of the large tationary mills an assumed amount for the smaller portable mills based on the actual number of days which they might run-which is quite a variable period; and the amount of mine timbers cut in the region and shipped to adjacent counties, upon which there is no definite check, was placed at 4,000,000 board feet. While the individual assignments are necessarily inexact we believe that the total, when made up as follows, is approximately correct.

V-v 200 -- x -, V+v n where V equals the present volume on the average acre; and 1.1, its volume n or ten years ago. The merchantable volume at present was computed as 635.53 cubic feet and by figuring from growth tables the volume of each diameter class ten years ago, the total volume at that time was found to be 477.68 cubic feet. Using the formula, we get 2.87 as the growth per cent. This can be applied like simple interest to the present stand, giving the annual increment on the average acre as 18.05 cubic feet, or about 1/5 of a cord per acre per annum. It would have been more exact to follow Recknagel's method (Recknagel, '16) and to have found a growth per cent for each diameter class, applying this as a percentage to get the increment on the volume of that diameter class and totaling these increments, but according to Chapman ( '21) it is not safe to apply such a figure over large areas because the average age, thrift, or other condi-· tions may differ widely from that of the sample area. If, however, this figure were applied to our 131,217 acres of upland merchantable timber it would give an annual increment of about 13,000,000 board feet, assum­ ing that a cubic foot is equivalent to 5.5 board feet. Whether this growth of about 1/5 of a cord per acre per year for upland timber is correct or not, it indicates that the annual growth is very low owing to poor stocking, to fires, and to lack of thinning at proper intervals. Baker ( '21) cites an example of oak in the sandy region of southern New Jersey where a thinned acre had increased in volume at the rate of about one cord per acre per annum, whereas a check plot near it, not thinned, had only increased 1.1 cords in seven years. An improve­ ment cutting in a stand of 20-year-olcl mixed hardwoods in the same state resulted in a gain of 9.4 cords per acre in 10 years, or, again almost a cord per acre per year. PHYSIOGRAPHIC FEATURES TOPOGRAPHY The area covered by this report may be divided for con enience into the Mississippi bottomlands and the interior highlands. The Mississippi bottomlands occupy about 18o/o of the total area of the 697,286 acres, with an average width of four and one-half miles. The relative width at two different places is shown on the Profiles sheet. This part of the area is cut by old river channels and is still subject to local overflows. Natnral drainage is poor, the river having an average fall of only six or seven inches to the mile.

Grand Tower limestone, a layer about 150 feet in thicknes , is well exposed in an old quarry a hort distance east of Grand Tower, in Jack­ son county. Lingle limestone and Meisenheimer shale are other repre­ sentatives of the Middle Devonian . The Upper Devonian is made up of two layers, the Alto Pa formation and the Mountain Glen shale, which i a black shale showing up near Mountain Glen, northwest of Jonesboro. Above the Devonian i the Mi sissippian, shown at the extreme right of Plate LXXI, and this is divided into the Lower Mississippian and the Upper Mississippian, the latter being known as the "Chester group." The Springville, or "calico," shale (locally called "ganister",) which is mined in some places to be manufactured into refractory fire-brick, is classed with the Lower Mis issippian. The Chester group is made up of lime­ stones, sand tones, and shale , from 700 to 1,200 feet in thickness, and it is partly in this group that the sink-holes in the region of Anna are developed, that entire region being a limestone area. Proceeding upwards, we come to the Penn ylvanian, who e lower layer is the Pottsville sand­ stone which forms the bluffs at Pomona, all of the northeast corner of the Dongola quadrangle being in fact mo tly sandstone where there is considerable poor, gullied land. Above the Upper Mi is ippian are the layers of the Carboniferou which contain coal beds developed at l\ (urphysboro, Herrin, and Harri - burg-more thoroughly described in the published geology of the Herrin quadrangle. The coal bed indicate that at intervals there were fresh­ water marshes which received an accumulation of plant remains, thi coal being formed during what i known a the Carbondale and l\IcLeansboro period of the Penn ylvanian. The Permian epoch, which fo ll ,ved the Carboniferous, was one of upli (t, faulting, and intrusion f lava, during which the eastern extension of the Ozark highlands occurred, and as a consequence of which we have faults, dikes, and volcanic plug formed in many of the southern countie . During Cretaceou and Tertiary time , clays, sands, and gravels were laid down, as shown in the lower right-hand corner of Plate LXXI, from Fayville to Tamms. After thi came the deposit of sands, gravels, and clays, with glaciation of part of the area during the Quaternary or more recent period. Glacial and w ind actio11.-As can be seen from Plate LXXI, the south­ ern limit of the Illinoian ice sheet extends across the northwestern corner o f our area. According to Savage and Shaw ('12), this last advance of the glaciers southwards covered about 1000 square miles south of the parallel 38 degrees. It left no sign f a terminal moraine, but worked over mate­ rial deposited previously, brought clown rocks, such as quartz, from Can­ a la, and filled up and modified former drainage channels. An example of PLATE LXXI I /"ti i===~i:r-.:i~"1"i;'ll"t':::!a LEGEND \ \ ~ l{ellow S✓-lf Lot:1m □f~llt:>W6rd'f 5i/f-Lc;gm .M,·xedLonm Scale I H= 1 /'f//e \ \ \ \ 324 the latter is found in the fact that at one time the outlet of Big Muddy River into the Mississippi was filled up, forming a large lake called "Big Muddy Lake," which was northeast of this region. Glacial striae, having a general north and south direction, are found just ea t of thi region at Bush, while in another place in the Herrin quadrangle they run south 30 degrees west. Glacial deposits have been modified or covered up in places by loes. , which was blown up by the wind from some of the great outwash plain formed by the glaciers. According to Savage, this may be of two kind , the deep loess, which has a depth of 50 feet in places, and thin loe about 10 feet in thickness, the two often shading so imperceptibly into each other that they may be considered parts of the same deposit. The thick loes may ha, e been deposited in the forested region and the thin loe in the undrained lowlands. The true loess weathers with a more or 1 s vertical face, gives a test for lime with acids, and contains the remain of land hell . A good example is found in the cut at Dug Hill, betw n Jone boro and \'fv are, along what is known as the Dug Hill road. South of the ·ache River in the Dongola quadrangle the loe s is not typical but is non-calcareous, and can hardly be distingui hed from the silt loam . SOIL TYPES A. Upland so1Js.-In the upland area the vanat1on in soils is n t marked. Prevailing opinion holds that loess is present in almost all of the upland soils in degrees varying from light deposits in the eastern section .. covered by this report, increasing to the west, to the true deep loess depo its on the bluffs from Dutch Creek, in the Jonesboro quadrangl , outh to Thebes. The true loess contains a considerable percentage of lime, and we have found lime concretions imbedded in the banks of the streams. The loess soils, according to the "county advisers" in thi region whom we have consulted, will grow good blue-grass, sweet clover, or red clover, and the presence of certain leguminous plant on top of . ome of these ridges shows that the soil contains considerable lime; hence is not at all acid, as many of the soils on run-down farms are apt to be. Two soil types, the yellow ilt loam and the y llow-gray silt loam, tog ther comprise O\'er 80 per cent of the upland soil . They differ in th fact that the yellow-gray silt loam is an intermediate phase, approaching the gray ilt loam on tight clay, being a mixture of the gray silt loam. with the yellow silt. The three main soil types are shown in Plate LXXII : the mixed loam in the bottoms; the yellow silt loam on the side of the hills and ravines; and the yellow-gray ilt loam on the top of the 1-idges. Roughly speak­ ing, the la t two types are of about equal ar a, and are o represented. PLATE LXXII [ TopograDhY corresponding to the soils ~hown in Plate LXXII. Con­ tour interval SO feet. Scale one inch to the mile. Arrows indicate st reams. . 326 The soil surveyors cover each section by "fortie " and their map agrees very closely with the topography (see Plate LXXIII). Near Alto Pass, when timber maps and soil maps were compared it was found that the present timber areas corresponded very closely with the yellow silt loam type of soil, the ridge tops and bottoms having been largely cleared. The gray silt loams are also found on the ridge tops, while the yellow silt loams are below, coming to the surface on the slopes. As the topography n ar the bluffs on the western side is a series of narrow val­ leys separated by long, exceedingly narrow-topped ridges, the prevailing soil type is the yellow silt loam. At distances varying from four to five miles from the western bluff, the ridge tops become wider and the yellow­ gray silt loam occurs with increasing frequency. These two soil types are both characterized by porous, friable surface soil and pervious subsoil . They are capable of absorbing large quan­ titie of water and are very resistant to drought. They do not bake hard when dry, but remain loose and porous. While rated high as agricultural soils, both types are deficient in nitrogen, although the yellow ilt loams of this area seem richer in nitrogen than the average upland-timber yellow silt loams. T he body of continuous timber follows closely the yellow silt loam area, not because of any relation between timber types and the physical or chemical nature of the oil, but because these soils are found over the very rough topography. Both the yellow and the yellow-gray silt loams are suitable for agriculture, but the yellow silt loam is found on the steep slopes which tend to erode if cultivated and hence have been left in timber. As a test of this statement, we have found that if the soil map of the Alto Pass region of Union county showing the yellow silt loam were uperimpo ed over the timber map made by our party, the two would closely coincide so far as the upland area is concerned. The soils derived from chert are apt to have a poor moisture-retaining capacity where the rock fragments are fairly large. This kind of soil resembles gravel, but the fragments are angular and flinty . The degree of chertiness is reflected in the type of tree growth, in the extremely cherty soils, the o-eneral forest of white oak, black oak, and hickory giving way on them to a very inferior post-oak type. The shortleaf pine on the we tern lopes of the bluffs near Wolf Lake is on a moderately cherty soil. B . B ottomland soils.-As the eroding process is general in the upland , the flood-plains of the secondary streams draining these · uplands are con tantly receiving a portion of the wash from the slopes, strips of sedimentary deposits being thus formed. With the exception of the val­ l~ys of the Big Muddy and Cache rivers, these strips are very narrow. In general such soils are mixed loams ( see Plate LXXII), and since they 3r _, lend themselves readily to cropping after drainage, almost every acre of them has been cleared. An exception, however, is the gray silt loam on tight clay along the Big Muddy River. This does not drain well and may be classed as an absolute forest soil. Among the other bottomland-soil types are the yellow fine sandy loam, the brown sandy loam, brown silt loam, and drab clay loam. Cypress swamps seem to predominate on this la t variety of soil. CLIMATE At Chester, on the upper boundary of our area, the annual rainfall is 45.18 inche and at . nna the mean temperature is 57.3 degrees F. The milclnes · of the climate at Anna can be judged by the fact that /llag11olia grandiflora flouri ·he as a street tree. At Cairo, just beyond the lower boundary of the region, the mean annual temperature is 58 degrees F. and the annual rainfall 41.6 inches. From this it can be seen that both rain­ fall and temperature are favorable to tree growth ; and only rarely is there a total loss of fruit due to spring frosts. II. Milling and Logging Operations and Wood-using Industries in Southern Illinois The awrnills of this region, portable and stationary, range in their daily cut from 2,000 to 20,000 feet. According to Seerey ('18), the smaller cut mentioned would rank a mill as belonging to Cla s A and the larger cut would indicate a Class B mill. Portable mills are usually equipped with rack and pinion or cable drive and friction or belt feed or a com_bined belt and friction feed, though many in thi region are run with a traction engine. A 25 horse-power engine, if properly handled, will keep a circular saw working to capacity and at the same time will run a mall planer and edger. The owner usually ha a circular sa"·, ranging in diameter from 54 inch upwards, with oli, Bur""3u of Forestry, Rulktin No. 36. 1903. t . S.

With such a table one can read for a tree with a given diameter breast-high outside the bark (o.b.) its size im,ide the bark at 8, 10, 12, 14, 16, etc .. feet above the stump, and look up the board-foot contents of a certain length log by any log rule. Jt also affords the data for computing the contents of trt>es in cubic feet or estimating top diameters of railroad ties. Volume tables in board-foot or cubic-foot units can also be easily made from good taper tables. w °' '-I D.B.H . 8 I 10 I 12 I Inches 8 7.2 7.0 6.7 9 8.1 7.8 7.5 10 8.9 8.6 8.3 11 9.7 9.4 9.1 12 10.5 10.2 10.0 13 11.3 11.0 10.7 14 12.1 11.8 11.6 15 12.9 12.6 12.4 16 13. 7 13.4 13.2 17 14.6 14.2 14.0 18 15.4 15.0 14.8 19 16.2 15.8 15.6 20 17.0 16.6 16.4 21 17.8 17.5 17.2 22 18.6 18.3 18.0 2'3 19.4 19.1 18.8 24 20.3 19.9 19.6 25 21.1 20.7 20.4 26 21.9 21.6 21.3 27 22.7 22 .4 22.1 28 23.5 23.2 22.9 29 24.3 24.0 23.7 30 25 .1 25.8 24.5 T ABLE X III .-T APER T A BLE FOR BLACK O AK, AvA, ILLIN OIS F ee t above the Stump 14 I 16 I 20 I 24 I 28 I 30 I 32 Dia meters inside Bark (inches) 6.4 6.0 5.5 . . . . . . . . . ... 7.2 6.9 6.3 , . . . . . ... . . . . . . . . 8.0 7.7 7 .1 6.5 .. . . . . . . .
