The following table shows the number of trees per acre with various 

 spacings : 



The number required for any system is found by dividing the num- 

 ber of square feet in an acre (43,560) by the product of the. two dimen- 

 sions. For example, the last number in the table, 680, is the quotient 

 obtained by dividing 43,560 by 64. 



COST. 



The cost of planting is not great. At ordinary prices $1.50 per 

 acre will cover the expense of plowing and harrowing. After the 

 ground is prepared the planting of small broadleaf trees will cost 

 about $2.50 to $4 a thousand, according to the method used and the 

 soil conditions. 



The planting of ground occupied by virgin sod is not only laborious 

 and expensive, but is generally unwise. The treatment of such land 

 requires the breaking of the sod, followed by a second plowing and 

 the cultivation incident to the growing of cereal crops for two or 

 three seasons, before the ground is in suitable condition for the plant- 

 ing of trees. Soils containing a large amount of sand can frequently 

 be put into condition for planting the year following the breaking of 

 the sod. 



The price of broadleaf seedlings at the nurseries in Kansas and 

 Nebraska runs from $1 to $6 per thousand. Some nurseries pack 

 free and pay freight on orders amounting to $10 or more. The 

 planter will do well to consult several catalogues before placing his 

 order. 



Evergreens are more costly, since they are transplanted in the 

 nursery to give better root development, and may be several years old 

 when finally disposed of. It is possible to obtain red cedar seedlings 

 as low as $4 per thousand, but transplanted nursery-grown cedar and 

 pine of suitable size will cost 10 to 20 cents each and more. 



WHERE TO PLANT. 



In a naturally treeless region there is occasion for planting almost 

 everywhere. Houses, sheds, corrals, and garden patches need pro- 

 tection and ornament ; planted groves will yield timber for posts, fuel,
