Doctor Bkanner asked as to the occurrence of coal in relation to the for- 

 mations described. Doctor Merriam asked if the base of the Keechelus were 

 older than the EUenburg basalt. Mr. Weaver suggested that the Keechelus 

 may there represent part of the series, due to overlapping. In reply to ques-

 ranged from at)out 3 to 40 feet thick, and the space occupied by them may 

 represent 10,000 to 20,000 feet. The mechanism by which this amount of space
