CREWS AND DAILY OUTPUT 
In the northern forests a crew usually has two or three teamsters, 
one or more swampers and one skidway man. One or more 
animals are driven by each teamster.

In the open pine forests of the South where there is a minimum 
of trail building, one or more teamsters may work alone, doing 
their own swamping and skidway work. The usual practice, 
however, is to have a swamper prepare the logs.
