Over a very large area, however,this little sill rarely exceeds 3 feet in original thickness, and itmust often have been less, while its outcrop can in many cases becrossed in a single stride. It is, of course, still repeated by folding,but now it and the associated beds fold together as one little group,or entity in the folding, together building up a sheet, and thus ateach complete fold of the group both the top and the base of thelittle sill are exposed in the outcrops. Xow, just as this sill, owing to its original hardness, folds onitself, and forms a homogeneous sheet when it thickens, so theHonestones on the margin of the Quartzite form a similar butlarger sheet when they not only thicken to the north-west but werecomposed of harder material originally. Here, however, the changeis no longer local, but is maintained over a very large a
