In the Pike's Peak region it is usually unwise to plant after May 20. Since this region is rather dry, the species used are mostly drought resist- ing. In altitudes of less than 'J,;)UO feet Western yellow pine (Pinus ponderosa) and Douglas fir (Pscitdotsuga taxi- folia) are best adapted. The Western yellow pine endures dry winds and is therefore used on the northwestern, western and southern exposures. Doug- las fir will not endure dry winds and must be used only on the protected northern and eastern exposures. Above 9,300 feet Douglas fir can be used on warmer aspects because of the better moisture conditions, and the colder situ- ations are planted to Engelmann spruce {Picea Bngelmanni), Limber pine {Pimis flcxilis), and Bristlecone pine {Pinits aristata). Lodgepole pine {Pinus contorta) takes the place of the Western yellow pine above 9,300 feet. Only stock of the best cjuality should be planted. It costs as much to plant a poor, sickly seedling as it does a vigor- ous, healthy plant, and since the cost of planting is the heaviest item of cost in reforestation work, it is economy to throw away unfit stock. The cost of planting operations may \ary between certain wide limits, even when strict economy is practiced. The following is a list of the factors which affect the cost of all plan
