Prof. Jones considers that they are almostcertainly not higher than the Timber-Vein group, and may in factbe the equivalents of that group. On the other hand, they may bethe representatives of some of the lower seams occurring farthereast, namely, the Lower Level Vein or the Catshole Vein. , however, inclines to the former view.
