Page 29 - by all earlier observers in this field. Mr. WP Cummins very aptly referred to it as "a peculiar conglomerate." It occurs in most frequent association with sand, quite often appearing as a basal layer under sandstone. Quite frequently it forms separate layers interbedded in sandstone. In the described sections it occurs interbedded in sand in
