of frequent occurrence in the Dahlonega district. It is only by a 
close examination from different view-points that the true nature of 
the rock can be made out. Along a fresh cleavage plane the rock 
has every appearance of a biotite-schist with a comparatively small 
amount of quartz, while sections normal to the cleavage, or form- 
ing various angles therewith, reveal the presence of elongated 
bowlders and pebbles in greater or less abundance. The individual 
bowlders and pebbles are to be seen to the best advantage in the bed

of the stream, where the surface of the conglomerate has been polished 
by the action of the water. They are also to be seen in considerable 
numbers in the residual clays on the hill slope, where they have 
weathered from the outcroppings of the conglomerate at higher 
elevations. 
The bowlders and the pebbles are both quite variable in size, but 
they are always greatly elongated in the direction of the schistosity.
