Spearfish Location

Hello,

Having tried to load Grass 4.1 on to my Alpha, i have finally been able to
get past the compilation problem by using the axp binaries .

When I start up Grass, from my start up file "Grass.start" shown below

:
GISBASE=/proj/ice/MODELS/Grass.alpha/axp
export GISBASE
exec $GISBASE/etc/GIS.sh

I am prompted with the GRASS 4.1 menu screen as shown

                            GRASS 4.1

LOCATION: This is the name of an available geographic location. -spearfish-
          is the sample data base for which all tutorials are written.

MAPSET: Every GRASS session runs under the name of a MAPSET. Associated
          with each MAPSET is a rectangular COORDINATE REGION and a list
          of any new maps created.

DATABASE: This is the unix directory containing the geographic databases

         The REGION defaults to the entire area of the chosen LOCATION.
         You may change it later with the command: g.region
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

LOCATION: sfbay_________ (enter list for a list of locations)
MAPSET: dunnj_________ (or mapsets within a location)

DATABASE: /regis/data_______________________________________

              AFTER COMPLETING ALL ANSWERS, HIT <ESC> TO CONTINUE
                            (OR <Ctrl-C> TO CANCEL)

As I haven't got any datasets etc , I wanted to know how to proceed, i have the source code etc for Grass4.1 and presume that spearfish (the example database )
is here somewhere , although I am unable to find it.

Any suggestions as to where it is etc, and how to access it using grass, also
what am I expecting to see.

Thank you

Jeremy
