134 A MANUAL FOR NORTHERN WOODSMEN 
The timber resources are known; also their location, and 
all related facts. The cut can be located for years ahead 
to the best advantage, so as to make driving and the haul¬ 
ing of supplies, for instance, come cheapest and handiest. 
4. A map system preserves information about the land. 
An old lumberman or cruiser has a lot of information in 
his head that is lost to a business when he dies or steps out, 
unless it is fixed in some permanent form. 
5. A concern knows what it is possessed of, and has that 
information in the form most easily taken in by all intelli¬ 
gent men whom it may be desirable to inform; for instance, 
stockholders, and possible money lenders. 
6. A good map system in a business may pay for itself at 
the first change of management. A new manager coming 
into a business is in the hands of his employees for years 
until he can get first-hand knowledge of his country. With 
the aid of a good map system working command of a big 
property may be had in a year. 
7. A reliable map system followed up for a term of 
years through a series of pictures of the land furnishes a 
record of its growth, and so enables a concern to grapple 
with the question of future supplies.
