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

The number required for any system 1s 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 1s 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,
