over the kaolin pockets, which pockets are ronghly about 10 feet in height 

 and 6 to 8 feet wide. The maximum thickness of the lignite and lignitic 

 clay is approximately 25 feet. Its top is covered by loose day full of 

 angular chert debris, typical hillside wash of Mi^onaiy Kidr^. 



On the northeast side of this pit occnrs a large ma^ of z^f-rrained 

 siliceous material, mentioned above, separating the pr-r^~: workings 

 from tJhe original pits of this mine, which were worked in 1911. 



The photograph on page 530, taken of the northwest side of the mine 

 pit, shows the relations of the different beds described above.
