28 ADVICE FOE FOREST PLANTERS IN OKLAHOMA. 



The owners were advised to plant strips of pure cottonwood 4 rods 

 wide on the south and west sides of the quarter section, to serve as 

 windbreaks, these trees to stand 8 feet apart each way. Immedi- 

 ately north of the south belt of cottonwood. and east of the west belt, 

 should be planted two rows of Russian mulberry or Osage orange, 

 1 feet apart each way. leaving a space of about 12 feet between the 

 cottonwood and mulberry tret 4 -. 



idle railroad crossing the tract will expose the plantation to some 

 risk of injury by lire, but if orchards are set out along the south side 

 of tin 1 right of way as well as to the north of it. and are properly 

 maintained, the forest plantation will he efficiently protected. 



ANOTHER PLANTING PLAN SUITED TO THE RED BED£ BELT. 



This plan, made for a farm near Berlin, Roger Mills County, Okla., 

 is applicable to a large part of the uplands of western Oklahoma, par- 

 ticularly to the region underlaid with the Red Beds deposits. 



The rock underlying this farm belongs to the Red Beds formal ion. 

 and i- a very soft, fine-grained sandstone, which weathers rapidly. 

 A large part of Roger Mills County is covered with sand dunes 

 derived from this rock, which readily absorb all the rainfall and 

 allow the water to percolate down to an impermeable substratum, 

 where it forms an underflow. The depth of thi- under How. at the farm 

 with which this plan deals, is from 15 to 25 feet. Springs occur along 

 the arrovos, and water may lie found 2 or 3 feet below the surface in 

 many of the draw-. The farm lie- on a table-land sloping south, 

 which skirts the south side of one of the above-mentioned ranges of 

 -and hill- at a distance of •"» or 1 mile- from the farm. The altitude 

 i- ahout 2,000 feel above sea level and about l"" feet above the North 

 Fork of Red River. 



The -oil on thi- farm i- a fertile, red, sandy loam, composed of very 

 line particles, and at least -J feet deep. It contains considerable quan- 

 tities of alkali, hut being also highly charged with gypsum, is capable 

 of bearing good crops. It i- not abundantly supplied with humus. 

 The subsoil consists of the same materials, hut i- more firmly com- 

 pacted, and often contain- undecomposed fragments of the underly- 

 ing \{r<\ Bed- rock. Both -oil and subsoil are receptive and retentive 

 of moisture. 



The climate of thi- part of Oklahoma i> of (he continental type 

 common to the Great Plain-. Seasons of bountiful rainfall are fre- 

 quently followed by other- of -canty precipitation. The intense heat 

 of the summer, combined with almost constant winds, causes the dis- 

 -ipation and loss of a large part of the precipitation by evaporation, 



No tree- grow naturally on the farm, and there are no indications 

 that any have ever grown upon it in the past, but the shin oak (Rocky
