Comparisons between the experiments and<br />

the archaeological material<br />

The experiments now enable us to look upon the archaeological material<br />

through a frame of reference. Figure 4 gives us the following information<br />

regarding Jettböle:<br />

<br />

to the sum of the experiments. Since the hammerstones from Jett<br />

böle range from 200 to 2300 grams, this result is very encouraging.<br />

The amount of fragments from Jettböle is lower than in the expe<br />

rimental series. Above all, this applies to the lateral fracture frag<br />

ments.<br />

The percentage of splinters is somewhat higher than all the experi<br />

mental series show.<br />
